ADA MP-1

Audio Proz Inv #: 72125

Guitar Processor. Unit has Rev 6/ Rev 5 Modifications. Engineering Sample. Better Overdrive/ Tube EQ etc. Back panel phone jack is for line level. Unit has high/ low output switch on top cover. Fair amount of rack rash and scratches. Fully functional unit with only some minor cosmetic flaws. #8- Condition


On my website is a clear explanation about ADA MP1 and mods. Without a doubt the 3 tube mod is a waste of time and money and actually will make the ADA MP1 run incorrectly. This unit operates on the principal that the FETs control the tube voltage and carefully inject distortions into the cathode of the tube and also, the programming on the front panel changes plate voltages to tubes! A remarkably clever design! Obviously, the people who offer this 3 tube mod and double transformer mod do not understand this circuit or its operations technology and they are misleading concerned players.

The modification that I do actually lessens the tube gain, lowers the noise floor, and adds equalization that is better for todays vintage sound. Players want more versatility in programming usual guitar overdrive effects. The original design is way too screechy metal in its overdriven character for too many programs. My alteration allows a wider range of programming to go from the metal to warm, driven to crank, to a bluesy overdrive whereby the overdrive and equalization controls are calibrated more in the middle range of its programming numbers; i.e. Number 5 on the overdrive is now a nicely driven sound rather than a badly overdriven sound but the ADA MP1 will be still be able to be heavily overdriven on an 8 or 9 setting. These modifications were acceptable to the ADA engineer at the time. In fact, he commented that the electro acoustic sound with my parts change was similar to his thinking too, in that it allows for more flexibility for front panel adjustment for even more guitar tube preamping effects.

I have done this mod for 25 years!! No complaints yet. Please call me directly for more info.

Re: International Shipping: We ship internationally often and have yet to encounter a problem or complaint. We are very careful to test the equipment before it’s packed and then to double box the machine with added protection when needed for front panels, etc. We are not amateurs or an ebay store; we know these machines very well and know what it takes to get them to you safely. We use USPS priority internationally which seems to be the cheapest. If you prefer another carrier (you should know who delivers to your area reliably) please let us know. Also please be aware of any tariffs that you may be responsible for upon pick up on your end. International shipping may be expensive but we will make sure it is not a headache on top of the cost. PLEASE NOTE THAT SHIPPING INTERNATIONALLY WILL BE A MINIMUM OF $16 EVEN FOR SMALL PARTS.
