I have finally yielded to the incessant begging of a certain member of this board, whom shall remained unnamed... yet has long, deep, dreams in the theatre.... and have decided to join the board...
I'll probably be participating here, more than other spots. If there are specific "inside the gear" questions ya'll have, I can try to address them, to the best of my ability and we can get as deep, or as shallow, as you'd like to get with this. I've been doing a lot of analysis of various amps (VOX, Marshall, Peavey, Fender), lately, and looking into some design ideas for op-amp based distortion units that emulate these types of things. We can also discuss amp mods, etc.
My two most recent, and successful, projects have been revamping SOLID-STATE amps (yes, that horrid solid-state). Both have been Peavey amps - transtube. I reworked my Peavey Express 112 to be voiced ala Fender Deluxe Reverb in the "Clean" channel and ala JCM800 in the "Lead" channel. Both channels, now, sound very nice. I'm not much a fan of Peavey voicing, which is what this thing was prior to the mods. I also added variable resonance/presence (damping) controls to the power amp sections of both of these amps. I can go from very little negative feedback (similar to the VOX AC30 power amp) to very tight feedback (ala solid-state) and everywhere in between. The controls are separate from each other so I can vary how "loose" the high frequencies, or the low frequencies, or both, are. This can also be done on tube amps. ;)
Anyway... I'm here... you can pick my brain... we can look at various designs and how they work, etc. We can talk preamp voicing and why tone control types (i.e. Fender vs. Marshall) don't make as much difference as what we think they do. :'(. There are tons of topics we can cover... we can even do some "Electronics 101" if you want to get started that way.
