This is the ultimate preamp. It's like having a truckload of amps in one rackspace. It even rivals the legendary (and overhyped/priced) Mesa TriAxis. If you play guitar, you owe it to yourself to at least try one of these.

The ADA MP-1 is a Midi Programmable Tube pre-amp. It contains two 12AX7 pre-amp tubes (I use GrooveTubes in mine) has midi capability and 128 presets available to store your sounds.
There are three voicings available: tube distortion, tube clean, and solid state. Tube sounds are great, the tube distortion has tons of gain, and the tube clean can be either crystal clear or pushed for a great blues sound. The solid-state circuit can be used for a clean sound only. The pre-amp also has a built in compressor (clean channel only) and stereo chorus with depth and rate controls, and controls for master gain, overdrive 1, overdrive 2, bass, mid, treble, presence and effects loop in/out.
The rear panel contains effects loop jacks (send/return - mono), an effects loop level knob, headphone jack controlled by a level adjustment knob, left and right outputs, midi in, out and thru and a line input jack (balanced) plus a phantom power connector for the ADA MC-1 foot controller board.
Words's cannot do this preamp justice, it will do ANYTHING from a crystal clear Fender/Roland to a Texas Blues to an all out balls to the wall shred.
Very easy to figure out, spend an hour with it and you'll know everything it does.
I've had mine for years, no problems so far.
The tube tone out of this is awesome. I use Groove Tubes and get a nice drive out of it. The worst aspect is ada is out of business, so parts are tough to get, although I've never had one go bad. For the price, these things are worth their weight in gold.
Where Obtained: Used
AC powered - Twin 12AX7 tubes. Stereo outputs.
Great blues and rock unit. Nice tube and solid state clean and distortion settings. Has a nice built in Chorus and Eq. The only thing I've found bad with these is they feedback alot - I've heard other musicians play these through a noise reduction unit or parametric eq to overcome the feedback.
Is easily programmable. Has a midi programmable foot switch that is a must for gigging out.
