mikhailgtrski Posted August 17, 2006 Report Share Posted August 17, 2006 I recently rediscovered my old ADA MP-1 preamp. I performed the last tube cathode-follower mod (from www.adadepot.com) last night and I'm really liking it a lot. Much more plexi-like. It has replaced my Marshall JMP-1 (which had power supply transformer noise issues). Just curious what other players are using...

Gorecki Posted August 21, 2006 Report Share Posted August 21, 2006 Still use mine. Mine was mod'd at the factory (when it still existed) a long time ago and I'm still not exactly certain what they did beyond making the effects loop stereo. Run Groove Tubes in it and will never let that little puppy go....NEVER! Quote Link to comment Share on other sites More sharing options...
GodBlessTexas Posted August 22, 2006 Report Share Posted August 22, 2006 The MP-1 is nice, but i like the Rocktron Piranha more. That's probably because of the built in HUSH circuitry on the Piranha. Do any of the mods cut down on how noisy the MP-1 is? GBT Quote Link to comment Share on other sites More sharing options...

Do any of the mods cut down on how noisy the MP-1 is? As the MP-1's bite is by daisy chaining two Ax7 tubes, it's hard to put something in between but realistically, I never had a 'problem' due to noise. I've always run it with a midi foot controller and always in the habit of stomping on a clean quiet preset when not playing. Granted it wouldn't take anything to put a noise gate on the backend of the preamp. At the same time I wouldn't use one anyway. The one piece of gear I've ever owned that will allow me to go to the extremes of 'from a whisper to a roar' with the turn of a volume knob. A gate would kill it...IMO Quote Link to comment Share on other sites More sharing options...
mikhailgtrski Posted August 22, 2006 Author Report Share Posted August 22, 2006 Do any of the mods cut down on how noisy the MP-1 is? There are noise reduction mods out there. I think they involve swapping out capacitors and replacing some of the op-amps. Mine is very quiet. The cathode-follower mod reduces the gain somewhat, but it still has more than I'll ever use. I run the MP-1 into a cranked tube power amp, which gives me most of the crunchiness. I get a little hiss if I crank OD1 up past 6 or so, but I think it sounds better with OD1 fairly low and OD2 cranked anyway. I have a Hush Super C in my rack, but it really doesn't have much noise to deal with. I haven't had much time to work with it, but my first impressions are that the higher gain patches on the MP-1 are a little thicker, and a little more open sounding than the JMP-1, but the cleans don't seem to be quite as glassy. It might just need some eq tweaks. Mike Quote Link to comment Share on other sites More sharing options...
