Overdrive pedals are a funny thing: some of us like to use them to get crunchy, amp-like warmth. Some of us like to use them to boost an already overdriven amp channel into the next level. And almost everyone defaults to a certain green box when they think of analog overdrive pedals. The Seymour Duncan 805 Overdrive was designed with those classic tones in mind as a starting point but this pedal has significant differences from the Tube Screamer, beginning with the chip that powers its sound. While early development focused on the same chip, SD engineers eventually ended up with the MC33178 due to what they felt were superior sonic characteristics (along with a lower noise level and longer battery life).
