I have here an excellent Tremolo pedal from Walrus Audio. This the the Version One setup- it is a bit larger and has more controls, I think. This does both the standard amplitude tremolo as well as the 'harmonic vibrato' of the early 60s Fender amps. (nice and chewy) It sounds fantastic but I do not use it. It has velcro stuck to the back. I am open to a trade for the following: Electro-Harmonix Freeze ZOOM Multi-stomp MS50-G Earthquaker Devices Afterneath Thanks for looking.
