Yeah I think that's best - however I bet someone on the Guitar forum will be able to do the work for you.
Are you going to install the internal kit, or have the 'brain' on the bass instead? Maybe a good idea to begin with. It's nice being able to choose what parts you want when you do the internal install, so you can have an assignable knob which you can set to do whatever you like on the unit (reverb level, A/B pan, synth shape, tone, drive level, EQ curve, whatever you can think of) and the buttons which can also be set to turn effects on and off and everything else or simply set to scroll up and down through patches.
