I've been hearing a lot of TS-9 users are going to 12v. My Chain has: Eb volume--Fender Tuner --Bad Horse, TSTurbo, Maxon Comp, Boss RV-5,BossTR-2--Boss A/B--Boss OC-2--Dano Phaser --Line 6 delay. Besides the Line 6, everything is running off a 9V 1spot, but i feel like the Octave specifically sounds like its not powered enough. Should some of these be getting 12V? I know the specs should say but all are 9V batteries. Thanks.
