Time synchronized FX. This is a great affordable and fun hands-on effects unit for the musician or DJ who appreciates high build quality and flexibility. Contains flanger, delay, distortion and tremolo modules. This unit has full MIDI control so you can record your knob tweaking into your sequencer or send continuous controller messages from your computer DAW to make parameter changes, etc.
The unit in the photos was sold, but we have another one in almost as good shape, minus the box.
