I am not into the death metal thing and I wanted to see what changing the tube variant would do to this unit. I removed the cheap Chinese 12AX7 and installed an NOS 5814A (military grade 12AU7) and the tone was much improved and the gain lowered. I wouldn't be able to use the unit as it was. Now it is useable. I tried it on my rack rig and it didn't fair well since the rig is already good. I then switched over to my Fender Super Champ X2 and it was like striking gold. sounds excellent. I don't use channel 2 at all and the Gainiac does really well with the SCX2.
