I'm running a TS9 in front of my dual recto to tighten up the third channel and I'm happy with it in that respect but changing to a clean tone is a major problem. I can't switch from my boosted high-gain tone over to clean very effectively so I just leave the TS9 on all the time. Can anyone suggest a way to overcome this problem without eliminating the TS9 from my setup? Your suggestions are much appreciated. Thanks.
