Well it was actually quite funny that you should mention doing a JMP like drive...I put the final touch on it today, dunno if it will ever hit the streets, but here it is, it is somewhat more aggressive than the plexitone, more bite and gain, very much an 80's sound for sure.
Here are a few clips, I also tried it with a 1982 LP with some mean humbuckers...sustain and harmonics for days...screamer...hehe
Even my strats where wailing like mad banshee's...so these clips do not do it much justice, but the studio is down at the moment, have to rerig the computer, and I really do not have the time right now, but soon hopefully.
Here are few clips, I used my Wolfgang on both.
And the next one.
