Got my Boss MD-2 yesterday! Sweetwater is known for fast delivery! 2 days! I replaced my Boss Blues Driver with this pedal! I finally got the sound that I was hearing in my head! Played my Hendrix signature white start and IMMEDIATLY heard that sweet Hendrix distorted, overdriven tone! A power stack pedal and Monterrey pedal on the vibe channel in the chain with the MD-2 was a little piece of heaven!!! Played through a Marshall DSL40C on the clean channel. Tone knob at 1 o'clock, bottom knob at 2 o'clock, distortion knob at 1-2 o'clock, overdrive knob at 1-2 o'clock and you're COOKING with gas and electric!!! Played for 2 hours straight!! I play blues, blues-rock, hard rock, R&B, jazz and R&B Gospel, no metal. With tweaking it probably could play metal if that's your thing. Do yourself a favor and pick-up one of these badd boys! Israel Foster hooked me up and gives great service at Sweetwater! I have a drawer full of pedals that couldn't cut the mustard but I expect this pedal to be a permanent member of my pedalboard! ROCK ON PEOPLE!!!
