Cheers!
With mine the Stomp supplementary switch is as wide as the gap you want to leave to the next pedal.
Actually, for a Stomp, the two switches are just momentary press going to a TRS jack, so making one into a project enclosure (you can get good quality aluminium ones for a few quid) is a pretty simple job.
The one I bought lights up too, so it's got that "essential" extra featurette...
On my board the MicroBass 3 preamp is the hub and the switcher along the front just connects to its fx loop and switches the 4 supplementary pedals in/bypass at the touch of a button.
That means you can switch out a pedal (eg. the Stomp), silently change its setting, and then switch it back in when ready.
