The Canvas Rehearsal sits at the end of your chain and does three things: gives you a real headphone amp for your actual tone, a proper metronome, and a way to jam along to backing tracks — all in one small unit.

The headphone side is the whole point. Whatever your board is putting out, that's what comes through the headphones — not some thinned-out, tinny version of it.

The metronome's genuinely good. Tap tempo, 40 to 250 BPM, adjustable time signature and beat accent, all shown on a small OLED screen so you're not hunting through menus to change anything.

For backing tracks, you've got Bluetooth straight from your phone or a 1/8" aux in if you want it wired. Guitar, click, and aux each get their own volume, so you can bury the metronome or bring it up front, whatever the moment calls for.

It's not just for headphones either — stereo in/out means it'll run into a rehearsal room PA just as easily, and full MIDI in/out with pass-through means it won't dead-end your MIDI chain if you're running other MIDI pedals downstream.

Small diecast enclosure, fits on a board without hogging space. Typical Walrus Canvas approach — nothing flashy, just a well-built tool that does its job properly.
