The real world 5150 III DOESN"T have a resonance control knob onboard - but the 5150 IIIS does! From the addendum of the manual available on https://www.evhgear.com/support/product-manuals ADDENDUM: All functions and features of the EVH 5150 III 100S are identical to the EVH 5150 III, except for the items and part numbers included in this addendum sheet. A. RESONANCE — Adjusts the low frequency response for each channel respectively. B. ADJUST BIAS and BIAS TEST POINTS — NOT USER SERVICEABLE. These features should only be used by an authorized service technician to adjust the bias of the amplifier tubes. The Line 6 are based on the 5051 III 100 amplifier NOT the 100S. 1 Quote Link to comment Share on other sites More sharing options...
zappazapper Posted November 23 Author Share Posted November 23 Well then in that case, I should have said "A 5150 HEAD without a Resonance control isn't a 5150 head". That's bizarre. The product page for the non-S 100 even says it has a global Resonance but it's not there. What's the point then? Quote Link to comment Share on other sites More sharing options...

Oh I'm not suggesting it's not a good sounding amp, only that for me at least, the Resonance control is what makes 5150s unique enough to bother with them rather than really any other high-gain amp. When I saw that the new firmware had a new 5150 model I just assumed it would have a Resonance control because, like I said, what's the point then? Do I need another high-gain amp sound at this point? Quote Link to comment Share on other sites More sharing options...

Maybe you should ask the EVH manufacturer, because what makes it weirder is the 80w, 50w head, plus the 50w and 40w combo, even the 2x12 combo, all have a resonance control.

It's the unique feature of that line. Peavey even put it in some of their non-6505 amps, like some of the Valve Kings. The guitarist from a death metal band I record has a VK212 and our standard setup has become the preamp of my Mesa Boogie .50 Caliber Plus into the power amp of the Valve King because that Resonance control just rumbles. It's possible that the non-S 100 has it built-in. Resonance is like the opposite of presence. Presence is high-passed negative feedback on a reversed control (0 is full negative feedback, 10 is no negative feedback), which reduces high-frequency distortion. Resonance is just low-passed negative feedback on a reverse control. Even non-Master Volume Fenders have high-passed negative feedback to reduce distortion, just not that you can control. Whether or not it's standard practice to add low-passed negative feedback to every high-gain amplifier to reduce low-frequency distortion, I imagine it's a primary element of EVH's basic power amp design and it's quite possible that the circuit is there even though it's not on a pot.

Yep, from what I understand that’s the case, and I found what seems to be a good explanation of why it’s not controlled by an external knob. Check here, in post #11 from GreatGreen. https://www.thegearpage.net/board/index.php?threads/evh-5150iii-should-i-get-a-100w-if-i-have-the-50w.2466494/ Hope this helps/makes sense. 1 Quote Link to comment Share on other sites More sharing options...

Presence is a low-pass filter for the NF, Depth/Resonance usually a variable high-shelf. Just looked up the schematic: the og 5150 III has a fixed 150Hz high-shelf in the NF on channel 2 and 3. To be clear this means that frequencies below 150Hz are boosted in the power amp. Or in other words: the speaker cab's low resonance (110ish Hz) is less tamed than the upper frequencies. There was a patent on the Resonance control by Peavey so Fender/EVH wasn't allowed to put it in the og 5150 III. Bogner used a switch instead of a pot and called it Depth (e.g. the Ecstacy) to get around that patent btw. 1 Quote Link to comment Share on other sites More sharing options...
