Help Tm-36

When I try to run my Boss Metal zone pedal via the effects loop, I cant use volume knobs to increase the volume. How can I get the set up for pedals and the Tm-36m

Hi CheVato,
What are you trying to accomplish running the Metal Zone in the effects loop? Any issues with running it into the front of the amp?
The volume knob affects only the preamp of the amplifier (before the efx loop), so what you're seeing is normal.

I can run it from the front but the setting one head alter the sound on the pedal. I have to constantly tweak the treble, bass, gain, and volume on the tm36 when I use my pedal and vice versa
