I own 2 very useful preamps.

I have used these ADA MP-1 preamps for a long time. I had them in a couple of racks that evolved. They were consistent and dependable. I ENJOYED the use of MIDI for a long time. I ran 2 MIDI controllers: one for changing just my tones and another for CC control of effects. I used the ADA MP-1 with Rocktron Replifex and Intellifex together. I used a Boss NS-2 to quiet the ADA MP-1 in the loop of the Boss NS-2 ran the output into a Tube Works Real Tube II preamp always on clean for use if the stereo fx loop. Powersection: Tube Works Mos Valve or Marshall 9005. 4x12 cabs

Articulate and crushing.

James Hetfield, Alex Skolnick, and Paul Gilbert all used these. Does 80s metal and beyond spectacularly. Built in chorus/doubler is nice, albeit with a tiny bit of output sap, but that's easily compensated for. Hot rodded Marshall tone in a single rack space. There's a ton of mods for these, but for my tastes, I see no reason for me to patake. Sounds great through tubes, solid state, or straight into an interface for recording (with a good impulse response, of course). I've owned two of these, the first when I was still in high school and the second one I acquired from a friend about a year ago. I've learned my lesson and will likely never part with the one I have now.

Amazing compressed distortion

A classic 80s staple. Of course, its all over the Gish album as well. I still have yet to find the same compressed saturated, tight distortion in any other pedal/amp. I use this sometimes with the boss gt3 (as effects/midi controller) . Great piece of gear!

The original, and still one of the best!

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!
