I wish you and your families a Happy Easter! Markus from www.cabIR.eu

Hands up guys, who thinks, that this reminds you NOT to be the real deal? Love this Helix sound!

Hi guys, i happily want to share the release of 5 new www.cabIR.eu USA COMBOS IR libraries based on some really nice, untouched originals. All libraries are as singles or as bundle with a 50% OFF introduction pricing available. FE-SREV72_CTS: Based on a Fender ™ Super Reverb from 1972, originally loaded with 4x10" CTS™ 10†Alnico speaker from1972. https://soundcloud.com/cabir-eu/cabireu-fe-srev72-cts-es-335-bluesy-style FE-VLUX65_C10NS: Based on a Fender™ Vibrolux from 1965 with 2x10“ Jensen™ C10NS speakers from 1965. https://soundcloud.com/cabir-eu/cabir-eu-fe-vlux65-c10ns-1 FE-VLUX91_EMI: Based on a Fender™ Custom Vibrolux CSR8 from 1991 with 2x10“ Emincence™ `blue frame` Alnico speakers. https://soundcloud.com/cabir-eu/cabir-eu-fe-vlux91-emi-strat MM-RP112_EV12L: Based on a MusicMan™ 112 RP One Hundred from 1979 with a 1x12“ ElectroVoice™ EV12L speaker from 1979 https://soundcloud.com/cabir-eu/cabir-eu-mm-rp112-ev12l-jazz MB-LOSTAR_SHADOW: Based on a Mesa Boogie™ Lone Star Special from 2006, loaded witha 1x12“ MC-90 Black Shadow speaker. https://soundcloud.com/cabir-eu/cabir-eu-mb-lostar-shadow-3 I wish all of you a happy new year! Markus

Nice :)

In the spirit of marketing flooding at good prices ... cabir.eu will not lag behind: 33%.33% OFF this Black Weekend :D https://www.cabir.eu/en/38-single-ir-libraries And as a repeated tip, to make life no harder than it is (it`s quite the opposite these days with the Helix, seriously ...) to find the sound (I can not say it often enough): Find your sound quickly, easily and purposefully: 1) Choose the amp and leave it on "default" 2) Choose a cab IR that will take you to "the ballpark" 3) Finally, use the Amp EQ to tune your guitar to the amp... ... and NOT to compensate for a given IR! The cab IR is the complement of your signal path! With the cab IR your sound stands and falls. Starting with the subjective right one makes it easier for you to find awesome sound without an everlasting tweaking! Trust in "keep it simple" ! :)

Holy Moly ... Impressive playing from Norway! Stian Lerstad Johansen combines some Amps from the Line6 Helix LT with cab IR`s from the www.cabIR.eu CORE 4 TONE Bundle: "The four presets that I´ve been most satisfied with. Made them myself with IR´s from CabIR. Mostly used Tweed cab and a Marshall cab. Really recommend these IR´s btw. Sounds terrific! Dr. Z: MR AX1960 Focus Cab 121 and Thiele Focus Cab 121 Vox: MR AX1960 C 57 and VX CA30TB Focus A 57 Fender Bassman: MR AX1960 Focus B 121 and FE Tweed Focus Cab 57 Fender Dlx: same as Bassman" https://www.youtube.com/watch?v=svSL1qQTi1w

Great Vox tone with the HELIX Vox Ac30 Fawn and the cabIR.eu VX-CA30TB_BLUE IR library, based on the same amp ... https://soundcloud.com/tmuka/helix-vox-ac30-fawn-cabireu-thiele-mix-57121-1 But also great: Combination of the same IR library with the Helix Bassman Nrm! Listen to this: https://soundcloud.com/tmuka/helix-bassman-nrm-cabireu-vox-mix-57121-2 wow ... great tones with the Helix!

Unexpected Sound with Helix and the new MR-AX1960_G12M25 library (more a "vintage" style cabinet, huh?! from user "Drop the Sun": https://soundcloud.com/mediumplayer/helix-lt-prs-archon Love the crystal cleans and was surpised, how "modern" "DropTheSun" let sound the Greenback loaded cabinet with his Helix ... cool :)

Great discussion and opinions of the new cabIR.eu "focus IR series" you`ll find here... And some clips with the Helix ... https://soundcloud.com/tmuka/helix-bassman-nrm-cabireu-vox-mix-57121-2 https://soundcloud.com/tmuka/helix-vox-ac30-fawn-cabireu-thiele-mix-57121-1 https://soundcloud.com/tmuka/helix-vox-ac30-fawn-cabireu-vox-ca30tb-mix-57121-2

Guys, i bundled 4 new cabinets of the new "focus IR series" and for an introduction i discounted this CORE4TONE starter pack that much (introduction price till 7th july), that nobody should miss it! Check it out! I`m sure, you will love it! I am really sure, you will love the new folder structure as the sound you will get out of these IRs! Clarity, easy to use, extremely balanced IRs ( key is FOCUS folder! ). You don`t have to tweak the amp sims with these to get greatest results! All the best (see above, if you ask yourself, what i mean ... :lol: ) Markus

Well, ... yes and no. Yes, because i felt, the pack was back the time not to my 100% satisfying. No, because i could do the whole shooting, processing, prodcuing new from ground up. Sometimes it just takes longer. Complete new re-shooting, processing and Cab-Pack building. But now it`s there: The cabIR.eu VX-CA30TB_BLUE IR library, based on a VOX â„¢ AC30 / 6 TB from 1995 with 2x12 "VOX â„¢ Alnico Blue 8Ohm speakers. The new "focus IR series" has a goal - clarity at all levels. On the technical side, I could keep the signal path even cleaner, the processing further refine. The Cab Pack itself focuses on the best features of the "pro IR series", the good and proven has been expanded. The result is a cab pack structure, which is easier, faster and more targeted to search, without compromising, as far as possible your own mix ambitions - on the contrary! cabIR.eu "idealized-NULL-Amp voicing": Mathematical exclusion of any power amp influences cabIR.eu "objective sweet spot method": Microphone positions determined for subjective microphone positions or individual preferences. Clarity! The _QUICKSTART folder with only a few IRs guide you through the characters of the individual microphones or speakers, and the mix paradigms of the FOCUS and MIX-CLASSIC folders. The FOCUS folder: The proven mix paradigm of the "MULTI" IRs of the "pro IR series" was further developed in the new FOCUS IRs. Keywords: Super Balanced IRs. Even more clarity! The MIX-CLASSICS folder: Classic mixes of microphone pairs, such as Shureâ„¢ SM57 with Royer Labsâ„¢ R-121 or "front" - with "rear" positions. SINGLE-MICS folder: As usual as MPT (time-aligned, minimal phase) and RAW (realphase incl. Authentic pre-delay time), at least 3 positions per microphone and speaker. Also nice that I could use a Royer R-121 ribbon microphone. After working with this, I slowly understand why it has become the studio standard for the amp acceptance with ribbon microphone mummified. Beautiful part. Not straight linear, but very Amp-likely, has its own character. The highlight, however, was a very special piece: A Neumann U67 tube-large diaphragm condenser microphone, predecessor of the U87. Freshly maintained by Neumann-Pope Andreas Grosser. Correctly, it was even a U269: Extra shielded for the broadcasting stations and the directional characteristics can be adjusted continuously. Working with this baby was a great experience. Character with no end, and insanely good-natured in positioning. It can hardly be wrong. In addition, one should not underestimate the very small things: The tiny Neumann KM 184. The small membrane capacitor makes a great sound! I had not thought so. This was also used for the 2 "rear" microphone positions. For further information, tips, and comments, such as, where and why ... you can get from the USER-GUIDE, or directly on the home page of the cabIR.eu cabIR.eu VX-CA30TB_BLUE IR library. Have fun ... Markus PS.: By the way and not uninteresting to read a comparison on TGP ... even if this was with a IR Mix from that cabinet of the first shooting, nearly a year ago ... never released, because never felt, i was there, where the pack should be. Now it is :)

Any winners here? If so, please check your private fb messages!

Attached the magnitude, FYI :)

Great! Thanks for the info, Alpag! By the way: Using this two IRs is similiar like just mixing the CAB_MULTI_M01 with the ROOM_R1 to prefered mix ratio, cause the AMBIENT_CAB_L contain the CAB_MULTI and ROOM_R1 to some degree. Only the REAR Mic would be lost, which also is mixed in the Ambient variants... just FYI :)

+1. And to make this clear, i will repeat it: IMO, For most accurcacy using a full modeled Tube Amp Sim like the Helix provides, the IR should not contain any actual (linear) power amp "response". It`s the job of the power amp modeling (& maybe some nonlinear modeling of cabinet behaviours) to fullfill these linear and non-linear events. Sometimes, most "accuracy" must not sound subjective best. So, the "T" version is just an option. If you like more "scoop", or you did not have any power amp modeling (using just a preamp section of whatever), It MAY be a subjective better opurtinity. In the first line, I would always recommend the "I" version with a good modeler. At the end of the day, the only thing, what`s important is: Use, what sounds best to you! Cheers :) Markus

+1, but: "A simple IR produced from a sine sweep probably won't capture this too accurately either, since it will change depending on how loud the sweep is." There maybe differences related to capture volume, but as long the speaker is driven within his specificiations, and also the chassis works as intended, no "bigger" particular vibrations, etc. than i doubt, that the differences would be really audible. Maybe for the gras root listeners. For the rest: Well, non-linear issues, convolution can`t represent in common, true. Those artefacts the modeling algorithm must add... Attached again a plot. Same cab, same mic, same mic position. It`s a shoot from a friend, so i can`t say more about, but he mentioned the only difference between the both was a volume increasement of the measurement signal (sine sweep) of about ca. 10db, he state. Also, i can`t exclude measurment errors while capturing. I did only the plots for the friend...

Just tried to simulate something with PEQ. see attached... perhaps these parameter settings could be also useful or a starting point... (don`t forget: low res center frequency can go much lower on open back cabs, specially 1X12"...)

Great thread! This thread discuss exactly the edge of the missing link, modeling can`t achieve perhaps not 100%, because the interaction between real cabinet and real tube power amp could be for sure modeled, but based on the assumption, how the impediance curve of a given guitar cabinet would look like. In the digital world, where the amp and cab block is separated, the Amp may can model the influence of impediance curve, but don`t know the exact impediance curve and low/high resonance of a given cab IR. Every cab will produce a dedicated response to the actual amp. `Cause the IR don`t have this information, nor can it transfer this information to the amp block. Nethertheless, we should not overrate this issue, because in fact, we can achieve great and authentic tones out of our "virtual" amp rigs, right? To be honest, i ain`t own a HELIX unfortunately (Axe-Fx here ...sorry), but this issue is the same to all modeling concepts, because of tecnical barriers, as i tried to explain. IMO! So, let`s have a look to this plot, i made years ago ... (FYI: The Amp and Cabinet was never used for cabIR.eu IR shootings!) (picture attached below) Here we see: BLUE: AMP DI (low damping factor). The current feedback of the given Amp it "see" of an actual, dedicated Speaker Cabinet. This frequency response depends on certain parameters, some of them: reactive load of the speaker cabinet, damping factor of the power amp, negative feedback, also resonance/depth & presence control settings of an tube power Amp, ... This influence in the frequency, we baked in to some degree in our www.cabIR.eu "T_ube Amp" Voicing, dedicated to the specific guitar cabinet. GREEN: AMP DI (high damping factor). As we see, the curve gets almost linear above the low-resonance peak, we see at 117Hz from the blue line. IOW: This Amp is NOT very linear below this area. RED: This is, what i called "I_dealized NULL Amp". The non-linearity of the green line was mathematical removed. The result is the "ideal" linear power amp with a theoretical ∞ high damping factor. These "I_dealized NULL Amp" IRs don`t contain ANY power Amp influences, just the frequency response of the cab/speaker + mic + mic position. The rest should be the job of the Power Amp simulation of the modeler. Although some people like using there modelers with real tube power Amps to passive FRFR (what the T_ube Amp" IR versions would get closer... Or others just like these more scooped IRs... So, when the approach is: As close, as the real thing, it does make sense to distract any influences of a power amp, when shooting IRs, because this should be the job of the virtual power amp simulation, which should also provide the nonlinear events like harmonics, gain, distortion, etc. So, what happens to the frequency response, when shooting with tube amp coloration (T_ube Amp) or exclude this influences (I_dealized NULL amp)? I did a little "slideshow", you can click thru and "see" how the frequency response change to a dedicated cabinet / power amp (so, not related to the example picture above...): https://www.cabir.eu/en/content/12-pro-ir-series-libraries-II (Related to the second "Virtual `scoop` Tube Amp color knob" slideshow. The first one shows the "virtual" P_Ush Amp version, containg only influences of the actual Tube Amp in the low res area. Anyhow: The most important impact seems to have the low-resonance frequency. The curve & the center frequency depends on the cab. Closed classic 4x12" cabs are mostly around the 115Hz area. But 1x12" open back combos could also have this los resonance in the 50+ Hz area! For that reason, all IR-libraries at cabIR.eu naming the low resnance frequency close the gap (as described above) a bit more... But as i said: Don`t overrate this whole issue! I don`t know the paramters, the HELIX support. As the OP described, the Axe-Fx has such parameters you can manually adapt to an used IR. But the problem stays: Normally, you don`t know the exact impediance curve. So, most of the guys don`t touch this "speaker tab". The idea from the OP, emulate this resonance curve using a PEQ maybe useful, maybe not. At the end, EQing is justified, when it helps to achieve the sound, you`re looking for. Period ;) Adapt from the BLUE line in the picture, i would recommend a bell filter boost with higher Q-factor for the low resonance ... and a shelving with lower Q-factor for the high resonance....

Yes, this makes 100% sense! The convolution / impulse response tecnique is a "linear" concept. It represent frequency response and time based events (reverb tail). So, no "non-linear" events can be achieved with this concept, like Gain, dynamics, harmonics, etc. That said with "some" i meant the frequency changes, the impediance (frequency) curve from the cabinet - low damping real (tube) power amp will generate. The impediance curve depends on the cabinet, the negative feedback from the power amp and other parameters... Long story short: Your findings match the tecnical behaviours:)

That`s interesting! Gear like the Helix should do the power Amp simulation. So the intended "correct" usage would be just using the _Idealized NULL Amp IR versions, not including ANY influences of a tube power amp - should be the job of the Helix power amp sim, right? The idea behind the T_ube Amp versions was, to give Users, who prefer still using real tube power Amps to drive their passive FRFR include some of the Tube amp coloration, based on the impediance curve of a dedicated guitar cabinet due low damping factor of Tube Amps. Solid state Amps have high damping factors, so they keep linear. Here the T_ube Amp IR versions may give back some of the tube power amp coloration / feel. The other solution is: Using just a preamp + IR as cab emulation. So, some of the Tube Amp interaction will be included as "linear print" in the "T" IR versions. That`s, what you did, when just using the preamp section of the Helix. Also very intersting! Your sample sounds really good to me, like it! May you reveal, what library exactly you used here? I would like to add this soundcloud sample to the cabIR playlist for sure :) In fact, you used the Ambient versions in a not intended way, but the result convinced, no doubt :) My intention of the Ambient mixes, was to give an impression out of the box, what you can achieve, when mixing a close mic (single or mix) + rear cabinet + room1 (left IR) / room3 (right IR). I use this mixing appraoch personally oftenly, when playing "silent" at home with In-Ears to get the impression of "Amp in the room" sound. Sample: https://soundcloud.com/cabir-eu/mm-112rp_ev12l-speaker-cabinet-impulse-response-library-room-mix-1 (EV12L IRs from an unreleased IR-library, i`m working on + Dumble Amp Sim + ES335). So, listen loud with HEADPHONES - that`s what it`s made and mixed for. All the "room" you here is from the room and rear IRs - no algorithm or convolution reverb included in the signal chain! That`s made by splitting the "just Amp Sim" signal in the DAW to 4 single tracks adding there 1 of the four IRs each in a convolution host, giving availability to the whole 500ms (24000samples) long reverb trails... so, i use the Modeler just as Amp and add the miced cabinet on different tracks in the daw in realtime... So, when using those AMBIENT mixes or room / rear IRs in the Helix, they will be truncated to 2048samples (ca. 42ms). In result, the room reverb tails get lost and just the "honk" of the room capture survive. Forgive me, it`s Axe-Fx, but here a demo of the above written concept. Not the greates tone, i know, but it was just for demoing the AMBIENT mixing concept:

Sounds great! Very "marshallesque" :) Added to the www.cabIR.eu playlist! Thanks alpag! Hope you enjoy the IRs furthermore :)

Yeah, always interested in ;)

True: The MR-8X10, based on a1968 Marshall 1990 Lead 80 is bright, as you will figure out for yourself if you listen to this comparison with the similiar cab and a vintage 4X12: Although, i love this cab for darker sounding Amps like the 1970 Plexi on the Axe-Fx II or certain "tweed fendrish" style Amps. Super vintage. reminds me to Black Sabbath (Paranoid) or Led Zeppelin (whole lotta love) kinda 60ies vintage tones. Combined with the tweeds, i end up in keith richards area *lol ... :) Ever tried doin` some mixes with the single mics from the RAW folder? Or with different cabs within the Sigi`s finest IR-library collection? Did you checked out my "HOW TO USE" slides, where i tried to put some background related tips in ... ? Maybe this will give some new ideas ... for own findings... ;) Cheers Markus

It´s the only quick & easy way i can guarantee easy "backrolling" - IF the worst case scenario - wasting your time to unsatisfaction - will happen (although i do believe, this will hopefully not happen) ... :o
