Looks sweet. Info please
I believe my PlexRod might be just what you are looking for. The "Plex" mode is basically identical to a '69 Marshall Super Lead Plexi circuit. The "Rod" mode is like a hot-rodded JCM800 - way more gain, but still all the characteristic Marshall roar. The "Zen" mode simply replaces the normal pre-phase inverter master with a Jose Master (popularized by Jose Arredondo through his great Marshall mods) - it has a different placement in the circuit and includes diode clipping - adds gain and also reduces volume - great for soloing. All three modes have independent masters so you can balance the volume for live use when switching between the modes. All modes and the effects loop can be switched via footswitch. You can also turn the amp into a straight screaming '69 Plexi by setting "Plex" mode and turning both the Plex gain and master on full. You can adjust the overall volume when doing this by adjusting the Post-Phase inverter master (PPIMV) on the back of the amp. I find that a good PPIMV does the best job of taming a screaming Plexi. Mine is done so that it is completely out of the circuit when it is cranked. You can also use the PPIMV to adjust the overall volume of the amp for live when switching between modes. The loop is switchable between series and parallel usage and there is also a line out for those who like to run stereo effects and separate amps and cabs in W/D or W/D/W arrangements. Everything you need for monster Marshall tone - both modded and straight in one amp and all footswitchable!
I should finish the prototype in a week or two (waiting for some choice resistors). I have spared no expense in bringing killer tone to this amp. I'm using the best components available including Riken resistors (carbon comp's sweet tone without the drift and noise), PRP resistors, Solen and Sozo vintage caps, etc.
