The Valcoder was designed to replicate the square wave tremolo sound that was available from the old Valco-designed amps of the 1960s. What the Valcoder has over those older units is an additional Depth control that the amps lacked – so you can get shallow and shimmery type tremolos as well as the full-on machine gun staccato choppy stuff. The Speed knobs range extends further than most other tremolos out there too – from super slow ‘I shouldn’t have drank all that cough syrup!’ pulses to pseudo ring mod/delay ping tones at the max settings. If you have onboard triangle wave amp tremolo already, the Valcoder can offer you a totally different flavor that still sounds amp-like and natural – all stuffed into our cute little Bantam Box enclosure.
