American boutique manufacturer Demeter Amplification has developed this tremolo effect with the ability to switch between 2 settings in speed, each with its own knobs for adjusting the Depth and Speed parameters. In addition to switching between the 2 tremolo effects, the In/Out button can be used to bypass, i.e., knock the effect out of the signal chain. Sonically, the effect is supposed to be close to the classic Fender tremolo effect (also called vibrato).
The box is used, but overall in excellent condition.
Base mode VAT.
