You can switch between three Over Drive types named tweed, carif, and britsh, and set the drive amount and level for each. Turning the level all the way to the left turns the channel off. There are also bass and treble knobs, allowing you to adjust the low and high frequencies. I bought it used a year and a half ago and only used it in my room. I mostly practice guitar acoustically, so it hasn't been used for a total of 10 hours, but I don't know how much the previous owner used it. I am selling it to reduce the number of items I own. - Model name: TRI-O.D. - Brand: TECH 21 NYC - Number of switches: 3 - Output terminals: 1 - DC input: Yes There was no knob noise.
