Thank you for checking out our USED Wampler Plexi Drive Deluxe British Overdrive Effects Pedal. This pedal comes with the original box, paperwork and bag. This pedal is in very good condition and works perfectly. Adapter is not included. Since the early '60s, Marshall Amplifiers have lead the way in rock tones with its legendary tight overdrive and coveted bass response. Early rock legends such as Jimi Hendrix, Led Zeppelin, Cream, and AC/DC helped lead the way in creating some of the most iconic rock tones ever produced and catapulted Marshall into rock legendary status. The Wampler Plexi-Drive Deluxe is a direct descendent of the Plexi-Drive Standard but with a few upgraded features. Like the original, the Plexi-Drive Deluxe's unique gain structure can cover everything from Vintage '68 style Plexi tones to the all out massive rock tones of a JTM-45 cranked to ten, or even eleven... With the addition of an all-new active 3 band Bass/Mids/Treble EQ stack – you can now have even more tonal control. With the bass boost option, you can emulate the feeling of the low-end thump of a 4x12" cabinet (or two) at the flick of a switch. The bass boost will allow you to dial in your low end at lower volume gigs or at bedroom volume levels. Along with the bass switch, We added a bright switch to add highs – which makes changing from bright to dark guitars a breeze. The Plexi-Drive Deluxe also features a one knob, pre-gain boost soft click switch that is voiced like that "famous overdrive with pronounced mids" – to help push your leads in to overdrive. Please feel free to call or email us with any questions you may have.
