I use my own firmware (available for free) with the BJ Devices TB-12
Page 1 foot-switches are:
[Scene 1] - [Scene 2] - [Scene 3] - [Scene 4] - [Scene 5] - [Backtracking]
[Drive] - [Boost] - [Reverb] - [Slapback] - [Tap Delay] - [Page Change]
Page 2 just replaces the scene foot-switches with other effects I use less often
[Pitch FX] - [Tremolo/Flint] - [Phaser/Flanger] - [Chorus/Rotary] - [A/B] - [Backtracking]
[Drive] - [Boost] - [Reverb] - [Slapback] - [Tap Delay] - [Page Change]
I can hold down the [Page Change] foot-switch to go to Page 3, which is just standard bank and patch selections.
The A/B switch toggles between dual effects shown above. For example in A-mode, I can use a Phaser (pre-overdrive), in B-mode, it's a Flanger (post overdrive).
I also use a volume pedal with the tuner activated automatically when volume is heel-down. I have another pedal that is a Wah in A-mode, and blends in an external organ effect (EHX C9 pedal) in B-mode.
Might give you some ideas
