The Marshall VT-1 Vibratrem is a simple-yet-powerful vibrato and tremolo pedal with a vintage tone, intuitive controls and a bulletproof casing. Switchable vibrato and tremolo modes emulate the classic sounds built into the tube amps of yesteryear, from faster choppy tremolos to slowly swelling vibratos along the lines of a "Gimour-esque" tone. Twin outputs let you take the Vibratrem into two amps or different effects chains, and the sturdy housing means you can count on the VT-1 gig after gig without the need for a backup.
