No.

To me this tone stack looks more like it was copied from an Engl amp. Same issue like the stack in a Marshall 2003/4. At high volume it will do nearly nothing to the tone, a bit mid scoop, not more.
this tonestack is from the diezel VH4, we found a schematic of the tonestack and the input

Informations about the diezel VH4, used for the conception of the DIEFET pedal from techniguitare.com
I tried to draw the tone stacks of the four channels.

Channel 1: typical Fender tone stack
Channel 2: 470pf treble cap, 22nf mid and bass caps, 39k slope resistor, 1nf cap from mid pot wiper to ground
Channel 3 and 4: 680pf treble cap, everything else like channel 2.

worked this out on a tonestack calculater, the result for channel two is lots of high filtering, slight cut at 1khz (less than a fender), and a big bass boost at around 80 hz. thats without factoring in the cap from mid control to ground, and channel three has slightly more mids, and treble.

What turrets? I didn't see any. Did I miss something?

Sorry to resurrect an ancient thread, but what is up with that orphaned V1A tube?
