Alesis QuadraVerb Simultaneous Digital Effects Processor

BY 1988 Alesis were on a roll, and with the release of the Alesis Quadraverb, they took things to the next level and continued to dominate the market for home recording. The Alesis Qudraverb's party trick of course, was that it could use up to four different effects, reverb, delay, pitch and equalizer, simultaneously. And it did so with 20k bandwidth!

GRAINY GOODNESS

Sound Quality 65%

Build Quality 90%

Usefullness 100%

Mojo/Funk 100%

Reliability 45%

Build quality: The buttons are nice. Its intuitive and fast to program. Its only like 6 inches deep, so with cables plugged in back that’s about 9 inches deep. Sound quality: Its grainy and noisy. Has unbalanced connections. Usefulness: Unique character that’s not easily replicated in-the-box. Mojo: I like to use Quadraverb for its great huge reverb decay because it makes block chords or strings sound beautiful, beefy, and full of grainy character. Reliability: The front panel and screen work great and interface is responsive and easy to navigate. But I probably have a bad unit because sometimes, especially when its first powered on and still cold, the right channel dips by like 14dB so i give the unit a little shake and wiggle the cables in the back to get it working correctly.

Had the unit in our electro studio, was great on all the drum reverbs. To my ears very 1980’s sounding, our unit required a new display.

I have one of these units, it needs a look at, makes a noise, hard to describe it, you only hear it when you turn the amp up, i have the shadows on the 100 programs, some of them have been changed to the list i been given. want the original shadows added back. do not want to any factory reset i might lose them all together.
regards
Andrew
