Ok. I misread the OP. I suspect the level sent to your delays etc is too high. Set Send/Return to Inst in Global Settings -> Ins/Outs to reduce the send level and/or use the controls in the FX block. The FX return input impedance changes with said Global setting: Inst=: high impedance, Line= low impedance. That is only affecting the tone if you plug in an instrument directly into one of the returns. Placement of blocks is not relevant.
-
Two things to consider: A stereo delay into a mono cab changes the tone due to mixdown to mono. Some delays have a headroom parameter to mimic input overdrive. Increase it to get rid of those artifacts.
-
The .hir files are Line6's proprietory IR file format to ensure use with their products only.

If you get a sound you like from one of the Vox amps and want a preamp to do that sound: You could try to match it with the Cali Texas Ch2 as an exercise / experiment. It's my fav preamp and very versatile. Try to get the sponginess / sagging right first by tweaking the master.
-
The character and overdrive of those amps comes mainly from the phase inverter and the power tubes which are not part of the preamp. Their preamps themselves are relatively weak and clean.
-
Sure; Less input impedance means more of the guitar's signal escapes through said impedance to ground. The input impedance is in parallel with the volume knob on the guitar. Lowering it has the same effect. (EDIT: This is a simplification - the volume pot is also in series at the same time). A pickup is a coil of copper wire with a magnetized core. It has resistance, capacitance and inductance that together act a resonant circuit which means at a certain frequency (1.5kHz to 4kHz) it "rings". This is often called the resonant peak. It is tamed when you decrease the input impedance. The sound looses character / attack / aggression / harshness depending on how much this peak sticks out in the frequency spectrum. It's like mustard - very nice on a Bratwurst, very annoying in a milk shake.
-
When you jumper channels the amp's input impedance is lowered, too. Try 230kOhm input impedance so that your guitar's electrics "see" the about the same load as if you'd plug into the amp directly. That will reduce "harshness" a little.
-
The 70's chorus actually is the low impedance exception in the modulation category.
-
The 70s chorus uses 22kOhm, because the real Boss CE-1 does. It is a line input device. You can set the input impedance to 1MOhm or put a neutral gain block as first "dummy" block. Or mess with the global settings.
-
If you use input 2 of either channel of your Bassman and want the same more mellow sound set the input impedance in the input block to 136kOhm.
-
But the schematic states 10KB aka 10kiloByte. I have a 2GB USB stick - will it work, too? But more seriously: stick to 10kOhm linear pots - at higher values only part of the control path of the pedal is recognized.
-
Correct. The pedals use TRS - tip, ring, sleeve. What needs to be done is to remove the ring signal. You can use a TRS cable where you open up one of the plugs and cut the ring conductor. Or modify the pedals and open up the ring signal path somewhere. Often people pull the pedal's TRS jack's middle connector so that it won't make contact when a cable is plugged in.
-
Where do I get those 10kB pots? In an app store?
-
Your amp / cab levels are too high as you found out yourself. Yes, the delays and reverbs have upper limits (fixed headroom) like real hardware reverbs and delays. Deal with it and lower the block's input signal level.

PLEASE VOTE: Different frequency curves for hi/lo-cut in cab block
Schmalle replied to Elephantstomp's topic in Helix
Already suggested before i.e.: EQ Cut filters FULL frequency spectrum AND adjustable db/8va Adjustable high and low pass slopes for cabs and ir's -
effect placement Pros and cons for effects in between amp-block and cab
Schmalle replied to Smashcraaft's topic in Helix
Formants! Pitch shifting something characterful as a cab will put it's eq bumps and dents in unusual places in the spectrum and shift the resonance frequencies of the cab. -
Vox normal channel or Matchless channel 1 with zero bass would be my intuition as a starting point.

effect placement Pros and cons for effects in between amp-block and cab
Schmalle replied to Smashcraaft's topic in Helix
Now add the memory footprint to it. The difference in file size of FW 3.15 and 3.5 divided by the number of IR files you computed. Some heavy black magic compression going on there. -
effect placement Pros and cons for effects in between amp-block and cab
Schmalle replied to Smashcraaft's topic in Helix
True. And the reason why the new cabs and IR's use less "DSP" is because the IR convolution stuff is now computed with the DSP's hardware accelerator which works in parallel with the normal computation. -
A high cut that only really does stuff in the last quarter of it's control range.

This is no speculation. The amp models replicate the speaker out signal of an amp. It matters what load / cab is connected when modeling. How much depends on how much current feedback the amp has. The impedance curve is an electrical frequency response of a speaker and it is indeed imprinted in the model. IRs on the other hand only contain an acoustic frequency response. -
What's the recipe for a McDonalds burger? Tip no. 1: specify the target tone. Edit: Tip no. 2: for OD1 channel sound the Badonk is closest.

Helix LT with Catalyst 100 - Cabs, pre amp or amp ?
Schmalle replied to steve_marsden1's topic in Helix
Amp blocks because the Catalyst has a neutral class D power amp. Preamps are more for coloring (tube) power amps. That's just a general rule of thumb though - there are preamps that are designed for flat or flat-ish power amps. -
For me a big step was to use the York Audio Marshall V30A Mix1 as a reference point. It is the filter that connects my amp's speaker out or amp sims with a flat speaker (studio monitors) and sounds like the cab I love. It feels like being able to virtually go into the recording room and play through a real cab. Most amps sound great through it. That said I use the Helix cabs quite a lot as a tone shaping tool - really fun stuff. And if you're after some recorded / in the mix tones that's a great way to get there.
