Reverb pedal designed to go infront of your amp. Two main modes. The first is an authentic drippy spring reverb for vintage surf and blues etc like an early 60s outboard Fender reverb unit. The second mode is a hall/plate studio style reverb that nails the late 70's/early 80's arena rock tone of a Hot Rodded Strat or Humbucker Gibson into an overdriven Marshall Plexi or JCM 800. Keep it the same size as the vapor trail or 805 with input/output connectors on top.
