Since rock music began, people have been cranking the volume controls on their amps in order to push them into distortion, an effect now known as "overdrive." The CB Overdrive gives you some refined yet gritty cranked-amp tones without the hearing loss. 
All the way back when electric amplification was invented, what we now know as “overdrive” was an unwanted byproduct of low-headroom amplifiers. Despite giving you the freedom to do so, product manuals sternly instructed against turning the amp’s volume knob up past a certain level, lest the amp distort. Amp manufacturers released bigger and bigger amps to allow for more volume without distortion. Eventually, everyone came to their senses and realized that amp overdrive was not only desirable, but cool. The only problem was that you had to… y’know, turn your amp up to ear splitting levels. This is where the CB Overdrive comes in. Our one-knob overdrive is internally fixed to sit right in the mix, giving you amp-like breakup regardless of where the volume is set. If you’re looking for a no-nonsense rock machine, the CB Overdrive delivers regardless of skill level.
