Solo/"Volume Boost" for JMP??

[killertone]

Metro zero loss loop and a Carl Martin Hydra boost. Done.

To truly boost the amp's output/volume for solos, you're going to need to have a foot-switchable 2nd Master added. Using OD/Boost pedals in the front end will simply drive the front end harder giving you more gain. It will not boost the amp's actual output/volume.

Yup.

Any level increase into the font end will increase gain and probably cut as well and not raise the volume, you need a second master.

I was going to say add an effects loop. But, it was said several times before I got down further on the thread
