"Made in Essex England. Ultimate Percussion "UP5" super analogue synthesizer system electronic drum module with 4 pads. Very primitive, but very cool old analog drum sounds similar to early Simmons. Includes levels for snare, tom 1, tom 2, tom 3, & bass drum. Module has volume control on each channel and includes a "P.P.S." section that controls decay, noise, and pitch. The other features work when pushed, but the button does not stay in (always intended to take it to an electronics guy but never found the time). The only other thing that needs addressed on the module is that tom 2, when struck, plays the analog tom sound in....... reverse I guess??? All of the others are fine, tom 2 sounds like a sweep, like the intended sound is being played backwards! Don't ask, I have never been able to figure that one out... Don't get me wrong, it sounds really cool. I just know it's not what it's supposed to sound like..."
