We have a J. Rocket Uni-Verb in like new condition. This replicates the Univibe sound of the 60's and 70's with an added spring reverb tank feature, plus modern appointments. Line outs set up so you can run the chorus/vibrato effect into your overdrive and then have the reverb as the last stage, a really nice feature, or run chorus/vibrato and reverb separately or simultaneous. Circuit runs at 24 volts like the originals, but uses standard 9 volt power supply. An awesome pedal that captures all that vintage vibe and mojo. These list for $429 new and are well worth. it, will let this one go for $250 in mint condition.
