Drunk Beaver OD-1

The Drunk Beaver OD-1 is a compact, budget-friendly analog overdrive pedal that recreates the Polish Exar OD-1. RockBoard's PedalPedia describes it as a Tube Screamer-style overdrive known for its rich low end and asymmetrical clipping, delivering tones that range from smooth boost to singing overdrive while maintaining excellent clarity¹. It belongs to the brand's XR series, a line of affordable pedals that revives, enhances and reissues former legendary Polish vintage pedals, mostly from the EXAR brand².

Where the circuit comes from

The Exar OD-1 sits squarely in the Tube Screamer family tree. JHS Pedals' history of the Tube Screamer lists the Exar OD-1 of 1989 among the versions of that circuit, alongside the Boss OD-1 of 1977, the TS-808 of 1979 and the TS-9 of 1982³:

Aion FX, which builds its own take on the original Boss OD-1, calls that pedal "a precursor to the Tube Screamer"⁴, and the Boss OD-1's own history includes the change from the 14-pin RC3403 op-amp to dual op-amps such as the JRC4558DD, the chip family associated with this style of drive⁵. The original Boss OD-1 came out in 1977 and was discontinued in 1985⁶.

For players comparing this pedal with the wider field, the practical difference is lineage rather than branding: the Drunk Beaver OD-1 traces to the Polish Exar version of the Tube Screamer design, while pedals like the Boss OD-1 represent the earlier Boss branch of the same story. Drunk Beaver's own range also includes other takes on classic drive circuits, such as the Khmelnytskyi OD, which pairs Boss OD-1-style op-amp tone generation with an OD-3-style tone stack².

Analog design and sound

The pedal is analog, built with high-quality SMD components¹. Drunk Beaver's description of its range, from smooth boost to singing overdrive with excellent clarity, matches what the Tube Screamer-style circuit is known for: a rich low end and asymmetrical clipping¹. It is worth distinguishing it from Boss's later digital take on the same name: the Boss OD-1X, released in 2014, delivers its overdrive using digital Multi-Dimensional Processing rather than analog clipping⁷⁸, and MusicRadar's review of that pedal notes it is unlike "the analogue original"⁷. The Drunk Beaver OD-1 stays on the analog side of that divide.

Power requirements

The OD-1 runs on 9V DC, center negative, and draws 10mA¹. That is a light draw by pedalboard standards, so it sits comfortably on a standard shared supply alongside other compact pedals.
