Hello. If the B2 has a 1/4" jack for the footswitch, any standard non-momentary (i.e. on/off switch) with two switches and a stereo plug should work. Fliptops sells nice ones for cheap, just search for them on google. Good luck!

Hi,
I'm not saying it's the best method, but I gave my 250-4 the old trial and error, and it worked out fine.
I found that Chassis was return for all effects, and what I did was turn on all the effects on the amp and close one lead at a time with the chassis lead and listened carefully.
A closed circuit will turn that effect off, so hearing what lead is tremolo, reverb (and fuzz and boost if You have them) is easy if You have them turned all the way up before You close the circuits.
Just do this for as short a time as possible, and if any of the leads doesn't make any difference don't try that lead again since it's probably meant to drive the indicator diods. I don't know if closing that circuit could do harm to Your amp so this is done at Your own risk. I'm just saying it worked fine and nothing broke for me.
Any additional leads to the chassis plus 2 or 4 effects leads are most likely meant to drive the footswitch diods, and can be skipped if You're going for a non-original footswitch that doesn't have the diods.
I've started building a footswitch according to this and it works fine, but getting it to look nice is... well I'm just loo lazy I think.
Starting to look at buying any 4-switch with momentary switches and redo the wiring so it fit's the amp.
Any footswitch with momentary switches should do the trick, and rewiring should be a breeze once You've figured out what lead goes with what effect.
