Bias Mod Mesa boogie Express+ 5:50 6l6 help? add pics help

[beasleybodyshop]

I did this same modification to my express 5:50, I used a fender style 10KL pot in series with a resistor ( can't remember the value)

It works just fine if your using 50 watt mode, if your using 5w it won't matter as it switches to single ended cathode bias.

If only they put the mode switches on a relay with a footswitch...then it would be a perfect amp!

Good to know - I was worried about the different power modes 5 watt 25 watt didn't want to mess that up. I think there's a you tube on how to mod those switches to be foot-switchable if I find it i'll post it.

found it - not sure if you can figure it out from the you tube maybe? not in english
