This is perhaps the most recognisable modulation pedal of all time... also, perhaps not. There's one little bucket brigade chip inside that serves to simply make everything awesome. This is surely chorus against which all others are measured. This one has been modded to use your regular 9v supply which makes things nice and easy.
