Seymour Duncan 805 Overdrive Pedal

Get more out of that classic 808 sound with lower noise and a longer battery life. With expanded gain and 3-band EQ, this pedal has a ton of tone to offer.

The Seymour Duncan 805 Overdrive pedal utilizes the infamous green overdrive chip to generate a rich and velvety breakup that just oozes from your axe to your amplifier. You have a dynamic gain control, a powerful level control, and active three-band EQ control at your disposal to craft your sonic signature to your heart's desire. True-bypass circuitry preserves the original character of your signal even when this pedal is disengaged, and a compact size won't eat up space on your pedalboard during your set. This little overdrive pedal pushes your signal to its max in warm tube-like overdriven fashion.

The Legendary Green Overdrive Chip

Your Seymour Duncan 805 Overdrive pedal is built with that irresistible green overdrive chip to forge a screaming output that simply will not be ignored. When you play around with your gain and level controls, you'll notice how quickly the overdrive begins to trickle in through your amplifier. You'll also notice how well this pedal responds to the subtleness of your performance and your guitar's volume/tone settings. Play around with each dial to hear your axe's natural character flow through in a rich and silky distortion.

The Power of Active Three-Band EQ Control

Many effects pedals fail to go the extra mile due to their passive EQ control design. The active design on your 805 Overdrive pedal boasts powerful EQ manipulation for your rocking pleasure. You have +/-11 dB of movement at 90 Hz, +/-11 dB of movement at 750 Hz, and +/-12 dB read more of movement at 2.1 kHz. You'll struggle to find another "screaming" overdrive pedal that commands EQ movement as skillfully as this compact companion does.

Massive Gain and Level Range

Because this pedal can take up to 18 volts of power, it boasts a lot of headroom via its level control. If you keep your gain settings low, you can use your 805 Overdrive pedal as a clean signal boost. Even at low settings, the gain control really fuels your signal with an addicting tube-amp-like color. You can also "stack" the overdrive on this pedal with your amplifier's overdrive setting for a flood of fat breakup -- just the ticket for any metal or hard rock enthusiast.

Seymour Duncan 805 Overdrive Pedal

The Seymour Duncan 805 is a very transparent, classic overdrive pedal designed using the chip found in the legendary 808 as a starting point but eventually ending with the MC33178, a chip Seymour Duncan felt had superior sonic characteristics along with a lower noise figure and longer battery life. The 805 features an expanded gain range and 3-band active EQ that is not commonly found in 808 style overdrive pedals.

It's so versatile that you can use it for a smooth, lyrical bluesy overdrive one minute and a modern metal crunch the next. Seymour Duncan started with the classic overdrive tones we all know and love but tightened up the bottom end and added more sparkle in the highs as well as more detailed note articulation. Whether you're after ringing cleans, a subtle boost, fat crunch, or even screaming sustaining solo tones, it's all in there. And unlike other overdrives that become thin when you refine the gain, the 805's 3-band active EQ lets you take back control over the low end while also fine-tuning the mids and highs.

The 805 Overdrive can be used to give your sound a boost with full overtones or to provide harmonically rich heavy gain with warm tube character. It's extensively developed and refined to be the perfect overdrive for pushing the front end of an already distorted amp, giving you plenty of output and tone-shaping capability whether you play hard rock, prog, metal, djent or whatever other heavy styles you'd like to throw at it. Whether you're running it into a clean channel or an utterly angry one, the sound remains natural and responsive. Like the Dirty Deed and Vapor Trail, the 805 is assembled at the Seymour Duncan Factory in Santa Barbara, California and is true-bypass.
