Compact crossover, signal splitter and effects loop
Designed for both guitar and bass, the XO splits your signal into high and low frequency bands, which are sent to two independent effects loops and then recombined.
This means that you can apply separate effects to the high and low frequency portions of your signal, or even send them to two different amps.
- Unlock a host of new sounds from your existing effects
- Great for using guitar pedals on bass
- 100% analogue – no digital processing
Press reviews

"I can envision the XO becoming ubiquitous amongst sonic explorers, engineers and producers alike. The XO opens the door to new sonic possibilities that were previously unavailable in such a user‑friendly format."

"The XO genuinely opens up your pedal cabinet to entirely new possibilities. David's really delivered a killer pedal here – that is as perfect an execution as you could expect for this manner of concept – all brought together in the most straight-forward, intuitive and pedalboard-friendly of formats."

"By splitting your signal into low- and high-frequency bands, and feeding them to separate effects loops, the XO lends a new, expansive vocabulary to the effects you already have."
