These amps sounds great..., what about their loudness? Are they to laud like plexis and DC30?  

Hi,

thank's for answer. I grounded all controls with wire, now works much beter. But i think it must be even more responsive, I know it will sound stupid, but i can't get to much treble or midle. All amps that I played has to much treble, midle... if you turn control to max. Except this one.

Hi,
I have problem with my plexi 50 Lead. Controls: presence, bass, middle, treble  are not responsive enough.  I can hardly hear the difference if i have treble,bass,...  on max or min. Master volume (PPIMV), bright and normal controles works fine.

Does anybody knows haw can I fix this?

thanks
