First, this is my maiden voyage into any forum of any kind; my apologies up front if I break any rules. I REALLY enjoy my F30 combo (stock except for new JJ tubes). The issue, however, is the white/hiss noise at higher gain/master volume levels. I'm predominantly a stay at home player and this amp excels at bedroom levels but when I have the occasional opportunity to turn it up, I can't get past the above mentioned noise. It's especially apparent on the clean channel, (which is one of the best I've heard). The gain channel noise is there but not really that bad. Would running a noise reduction pedal thru the FX loop help quiet down the noise? (I run the mix at 50% for time based effects and EQ). I really want to keep the amp but I'm having a really hard time getting past the clean channel noise. Maybe proper counseling would help. Also, I'm a tube amp simpleton, so if someone out there has some advice (mods?) I'll do my best to understand. Thanks!
