Something I think is important is to understand the different modes:
The B14 has three different modes: Memory / Stomp / Edit, which can be toggled with the button in the upper left.
Edit is for editing your patches, though I’d recommend to do that on a computer with Tonelib Zoom, or if you need to, the default Zoom software (which isn’t to bad, Tonelib ist just a bit better). You basically can move the cursor to any one of the 5 effect slots, and select whatever effect you want to have there, and then change the settings of this effect with the 4 knobs. Each effect has up to 4 changeable settings (a Big Muff for example: Sustain, Tone, Balance, Volume)
in Memory mode, you switch between different patches / presets. What you can do is for example move in that mode from one patch to another. What I have done is for example I have one patch for “Invincible”, and then another for “Invincible -Solo”, which I can toggle between via the foot switches. the left one moves down a patch, the right one up.
In this mode, the knobs will control a global equalizer which is always at the end of the chain, kinda like a sixth effect which is always the same for all the patches.
Moving between patches takes some getting used to: with the 2 big foot switches, you only toggle between a set of ten presets. Between 10 - 19, 20 - 29 - 50-59.
You navigate between the groups of ten via the buttons with the number 1 - 5. This works quite well if you have understood that, most people should be absolutely fine to move between 10 of those, so no need to switch between the banks of 10.
The stomp mode for me is good for learning about effects: This one kinda shows better what the Zoom is doing: chain up to five effects in one patch. In this mode, you use the right foot switch to move from one of the five effects to the next, with the left, you toggle it on and off.
Or, you can see the small buttons from 1 - 5 as itsy bitsy, tiny foot switches, each one of them toggles one of the effects. So kinda like 5 really tiny pedals in a row.
What I think falls short on the Zoom is editing effects on the fly. You have to move into edit mode every time, and can’t fiddle with always there knobs like on “real” pedals, which would be more intuitive.
