Hi folks, im kinda in trouble with setting up my triple recto with a boss gt10
and im afraid im gonna be fryin my speakers (gt75s), because at my presence settings, of course mainly in channel 3, the amps suddenly beginns blasting a Really ear piercing high frequent hissing and noise carpet, when I turn the master to recording/stage levels
With master around half, its not there, but amp already seems noisier
I dont even know wether "high frequent hissing" is the proper word for the noise problem, englishs not my mother s tongue, sorry!
Ive already read through this topic and test different solution suggestions, but none that i tried worked so far, maybe ive forgotten some important one

What Ive already tried:
1.) Putting a DI box with ground lift on between all cables from and to the mesa (though i didn test it between the guitar and the gt-10, but that wouldnt make sense, would it?)
2.) Removing the cable from guitar to gt10 completly - Still there (!)
3.) Only guitar - cable - amp , no gt10 - No ******* hissing (!)
4.) messing around with the output lvl, send/return lvls on the gt10. messing around with the knobs on the back of the recto
Other relevant facts:
The amps loop was modified to be switchable between parallel and serial via a toggle switch on the back, i dont know if it was done by a professional
also got an NS-2 laying around, may be useful for a solution? Though wouldt like to add another piece to my rig, hopefully its solveable with only amp and gt10 (and footswitch for amp)
Thx mates!
