Hey guys. Just an update. I built the volume boost switch. It took 5 minutes and it works great. I built it into an old 4 button footswitch so now switch 1 changes channels, switch 2 is empty, switch 3 is boost, and in the switch 4 spot I have a 250k pot which changes the range of boost from 0 to about 6 dB in my estimation.
It also seems to add a bit of low mids or something that fattens up single note passages. Maybe that is just a result of hitting the power tubes harder.
Anyway it works great for all you rm50 users out there. I worked off of the photo in the thread I posted above.
Thanks.

Glad you got it up and running quickly! I got a second Randall footswitch for my RM50 (same one as the channel switch) and used that to make the boost pedal. But I like your idea of combining them all into one box.
Also, as you may have already discovered, the amount of boost changes depending on where you have the amp's master volume set. The higher you set that, the higher you need to turn up your boost voluime pot in order to get a good volume jump.
