Hey all.
I just wanted to share a successful mod I've done to my BH5H.
So I've seen a few boost mods for this guy and I said, hell... it already has a boost! Instead of having the toggle switch on the amp, I figured we can just move it to a pedal. While that would be OK, it wouldn't be ideal. Too many wires to run and you would have high-voltage underfoot. So, I decided to use a relay. In my case, I had to use 2 relays to get the desired affect just because I used what I had available but only one DPDT is needed. I am only sending 9-12VDC to the first relay to keep them open, which is prefect for a pedal board. It works great! Switches as fast as the toggle.
Check it out.

I have no idea what you just did there, but pretty cool.

It's actually easier than it looks. Instead of the 3/5w switch, I put a relay (which is a switch that is triggered electrically) in it's place so I can use a foot switch in place of the toggle that was originally there. The reason for the relay, and not just a simple foot switch, is the amount of electricity being switched, cable distance, and a few other issues that can arise. Now I can just send it 3-24v to switch the relay rather than have 350+ volts under my foot.
