$20 · Behringer Tweakalizer with Power Supply

This is a pretty random piece of gear. Never fully figured out what purpose it serves, but I had fun with it! Some of the audio features are not really useful, but the filter and EQ are very powerful, the pitch warp is effective, there's a delay, weird record scratching simulation, you can hook a record player up to it if you want along with any standard RCA jack sound source, and there's even a rudimentary sampler you can tool around with in this thing. A genuine oddity that's been out of manufacture for a long time. Might good for noise artists or prank phone callers?
