This guys at Fulltone did a bang-up job with this monster. Based on the original Shin-ei circuit, this vibe gives players all the swirl, throb, and JUICE they could ever need all while seamlessly integrating the effect in its own rock solid expression pedal. The depth, volume, and switching controls are straightforward and very sturdy. I havent meddled with the internal trim pots yet because the effects sound great straight from the factory. The Mini DejaVibe 3 is definitely one of the best classic vibe effects pedals available and is a great value for the price.
