Selling to organize my equipment. I was quite interested in this and bought it. It's close to a Fender amp, isn't it? The presence control suggests they really wanted to faithfully recreate a Fender amp. It works well. The distortion is, shall we say, grainy and rough. It's to my liking, and it has a good character. Price negotiations are welcome. The Big Tweedy Drive is a drive pedal that recreates the sound of the "Fender Tweed Twin," a combo amp that is extremely popular in the history of Fender amps. This amp is known to have been used by top guitarists such as Eric Clapton, Keith Richards, Joe Bonamassa, and Rory Gallagher, but it was only manufactured for a short period from 1955 to 1958, and it's extremely rare to even see one in person. With this compact Big Tweedy Drive pedal, you can get the amp sound that supported the golden age of blues and rock simply by connecting it to your amp and turning it ON. It has four knobs: VOLUME for volume control, DRIVE for distortion control, TONE for high-frequency tone control, and PRESENCE for adjusting the top end of the tone. It features high responsiveness to picking, and a gritty, grainy sound that conveys the roughness of the wound strings, reminiscent of the tone of late 1950s American amps. Thank you for looking.
