Thanks for posting, this is a excellent tip that everyone should try out
Also when you do this, the bright control becomes super sensitive for dialing different character.
Takes a few little adjustments to configure the output levels to avoid clipping, but well worth the effort tweaking.
It'd be fun to make a 'Jim & Terry Marshall' inspired amp. Those amps are super dynamic and (in real life) you have to use the guitar volume to keep things under control.
