FullDrive2-Mosfet Housed in a beautiful powder coated Blue 16ga. steel enclosure, the dual-channel FullDrive2 gives you the best of both worlds. The first channel is the "Overdrive Mode" capable of clean boost or non-compressed overdrive or choose light to medium softer overdrives all while retaining your guitar's original tone. The Tone knob is a very effective presence control that can smooth out or add upper harmonics. The second channel is the "Boost Mode" with its own separate distortion control for medium to higher gains with a more singing violin-like sustain! In 2007, the FullDrive2, the most popular boutique overdrive ever made, and staple on many pedalboards for years, became the FullDrive2-Mosfet, sounding better than ever before. One mini-toggle lets you choose between a "Vintage" FD2 sound with mid-heavy tones that cut through the mix and "FM (flat-mids)" for a more natural, transparent sound that works awesome with a Strat's neck pickup. The other mini-toggle lets you choose between Mosfet and Normal clipping modes. Normal mode is even more asymmetrical, sweeter and more open, with no "blanket" over the sound. And, of course, the FD2-Mosfet features super-bright LEDs (borrowed from the OCD) and Fulltone's exclusive "no-thump/no-pop" True Bypass switches. We are the first to offer a switchable "Boost" Channel in an overdrive and manufacture our own Super-Duty 3PDT footswitch allowing True-Bypass plus LED.
