4 CM - reduced max volume, is using the serial loop the problem?
I currently use a boss gt-10 in 4CM with my marshall JVM. The parallel loop has signal bleed on this amp so I'm using the serial loop instead.
The only problem with this is that I think output of the GT-10 is limiting the total volume i can get out of the amp. Im consistently having to run the master pretty high. While there is plent of room on the output volume of the GT-10 (it's only at a quarter) pushing it any further clips the meters on the GT-10.
So what I'm wondering is, the output of the GT-10 simply not sufficient for the poweramp stage of the amp? Would I benefit from giving it a lift with a transparent preamp of some kind before the power stage? Is it possibly an impedance type issue or something like that?
Alternatively should I just go back to the parallel loop and live with the bleed?

If you ignore the meter can you hear any clipping if you turn up the GT output? That should sort your volume level, then you need to deal with any clipping in the GT - can you adjust the input level or the send/return level on the JVM?
