I just picked up the following, heavily discounted pedals from JRRShop (blowout sale) to use with the Octatrack. Nothing fancy as far as audio routing - they’re just going to go between my viola preamp and Octatrack input:
Way Huge Echo Puss ($116)- Analog delay that, based on demos, sounds close to the classic Deluxe Memory Man. Didn’t need fancier delay features like tap tempo and MIDI sync, because the Octatrack’s built in delay handles those just fine. What I got this pedal for was the ability to manually mess with delay time and repeat (for self-oscillation!), though the knobs look big enough for foot tweaking too.
Akai E2 Headrush ($89) - Akai’s tape delay emulator/looper. It’s no Strymon El Capistan, but can’t argue with the price. More importantly, I will gain the ability to record as many loops as I want without worrying about the dreaded “Dub Rec Aborted” random error or the “Rec Mem Full” error. I’ll still use the Octatrack pickup machines here and there, but the E2 will probably take quite a bit of load off of my mind when looping.
