Gilbert had two ADA MP-1s in his rack the late 80s and early 90s. "Pretty much one of my favourite things of all time, the new ADA MP-1. The real cool thing about it, is that, not only does it sound great, but you get some incredible switching with it. By pressing one button you can change everything that's MIDI, plus kick in stuff in the effects loop."more
I'm not going to recount the long list of classic records that this thing was used on, or all the legendary players who still have at least one in their rigs. This was the first MIDI-programmable tube preamp, and it was quickly copied by both Mesa-Boogie (Triaxis) and Marshall (JMP-1) to great success - to my ears, their copies of this design were the best products either company ever offered. Great cleans, overdrives, and way more gain than anyone could ever need - although there were modifications you could make to tweak the gain and EQ structure to get it exactly how you want it. They are a little noisy (like most tube amps of its day), but the aforementioned mods usually include a noise-reduction tweak to fix this as well. If you can find one, you should get it. No, wait - don't get it, I'd like to buy a few more, and I don't need you all driving the prices up!
