The Centavo Overdrive Pedal from Warm AudioDial in a little gain for a clean boost, or crank up the treble for edge-of-breakup and biting overdriven tones. The custom-molded champagne-gold chassis offers Gain, Treble, and Output controls on the front panel, which changes the value on the high-pass filter to provide an extended low-end response from the guitar's lower strings.FeaturesPremium components including TL072 op-amps, vintage-style diodes, and charge-pump regulator Buffered bypass operation MOD switch on rear for extended low-end response Custom-cast golden enclosure with accurately tapered oxblood knobs 1/4" instrument input (Inst) and amp output (Amp) jacks Powered by 9V battery or standard 9 VDC pedal adapter Main Uses Clean Boost With the Gain down and the Output up, the pedal acts like a clean boost that adds a little bite to the channel as you increase the Gain. Drive Dirt The original pedal is also well known as a great pedal to add in front of a dirty channel, whether used with a British (think Marshall) or American (Boogie) amp. Unlike the clean boost settings, players often engage the gain more here, so it hits the channel extra hard, with overdrive coming from the pedal. Transparent Overdrive If you want to take a channel to a nice transparent overdrive sound for rhythms or gritty solos over clean parts, the Gain knob has a lot on tap and offers a wide range of usable saturation while keeping the character of the amp and guitar well preserved.
