EarthQuaker Devices announced the Scrolls Bass Odyssey on May 14, 2026, a bass preamp and overdrive pedal developed with Japanese bassist Kentaro Nakao, known for his work with Number Girl and Crypt City¹²³. The company describes it as an all-analog, true bypass pedal built one at a time in Akron, Ohio².

The pedal combines a drive channel and an active EQ channel, each with its own footswitch¹. The drive is described as tube-amp-like distortion inspired by a rare overdrive pedal in Nakao's collection²³. A Blend control mixes clean signal with the driven tone, and a Bandwidth control sets where the clipping is most prevalent, with lower frequencies counterclockwise and higher frequencies clockwise¹³. The EQ section has Bass, Middle and Treble controls plus a Variable Frequency control that can cut or boost frequencies from around 20 Hz to 10 kHz¹²³. Three push buttons shape the tone: Deep adds an 80 Hz boost, Process scoops the mids, and Bright adds a 5 kHz boost¹²³.

The pedal has three outputs that work simultaneously: a buffered parallel out for clean signal, a balanced XLR out with analog speaker cabinet filtering, and a 1/4-inch output²³. An effects loop sits between the drive and EQ channels¹²³.

Pricing is reported inconsistently. Gearnews gives $393 and says the pedal is available to order at Thomann¹; the same page's retailer listing shows $375.00¹. Bass Musician Magazine says it is available now wherever EarthQuaker Devices are sold, without a price².
