Adding Reverb to Marshall Replica TMB 18W

[blackwhaleamp]

I changed the Reverb input from the Cathode Follower to the Master Wiper. If I leave the signal at the Cathode follower, the Master does not make any effect.
Now the reverb is loud enough.
I still have an issue with the hum. It is very loud and it changes with the Master. But that's for another day. I will investigate first in the forum

The hum issue is almost surely grounding. It's my experience that it's best to iso one shield from the tank and treat the input and output as separate circuits rather than all lumped together as "reverb circuit".
