Since the early 1960's, Marshall Amplifiers have lead the charge in rock tones with it's iconic tight overdrive and renowned bass response. Rock legends like Jimi Hendrix, Led Zeppelin, Cream and AC/DC broke new ground by creating some of the most legendary rock sounds ever produced, sending the Marshall name into the rock stratosphere. Featuring an all-new Mid Boost circuit switch that has never before been featured on a Wampler Plexi style pedal, the Plexi-Drive Mini delivers a powerful, vocal, tube-like boost by tweaking several gain stages of the circuit simultaneously. These switches in combination with the Tone and Gain controls offers outstanding tonal versatility from a mini pedal. While many players enjoy stacking other overdrive pedals with the Plexi-Drive, the Plexi-Drive Mini includes changes to the gain stage and EQ response within the Mid Boost circuit to achieve the same effect to an impressive result. With plenty of gain on tap, things can get loud - and with the unique Bass Boost switch, this pedal emulates the tonal variation between a 4x12 and 2x12 speaker cabinet. Features Built in the U.S.A.
