It sounds like you're dealing with a tricky issue there. If the fuse is blowing consistently after 20 minutes with high gain pedal use, it could indicate a problem in that circuit or the power supply. To troubleshoot, try using the multimeter to check for any unusual voltage fluctuations or shorts in the pedal's output when connected to the amp. Also, inspect the connections, ensuring everything is properly soldered and grounded. Consider checking the pedal's compatibility with the amp's circuitry too.
Regarding other aspects of your inquiry, have you tried testing different pedals or swapping out cables to rule out external causes? Additionally, regarding your use of the TMB channel, have you adjusted any settings or configurations within that channel specifically? Sometimes, certain settings might interact unexpectedly with pedals, causing issues like fuse blowing.
