Mad Professor Big Tweedy Drive gives you the overdrive sound of a 1950's Fender High Power Tweed Twin in a pedal. This exact amp model has been used by Keith Richards, Eric Clapton, Joe Bonamassa and Rory Gallagher to name only a few. Big Tweedy Drive acts just like the original Tweed Twin regarding dynamics. You can control the gain with your playing dynamics and adjusting your guitar's volume pot.
Works great with other overdrive and boost pedals. If you want more gain, just place a booster or another overdrive in front of the Big Tweedy Drive.
