A clean channel and a distorted channel. Okay, here's my plan. I have a QSC RMX850, an Ampeg SVP pro, and an Ampeg BSE410HLF. I had the thought of getting a sansamp RBI pre, and using that one for clean, and the ampeg for distortion. Would it be safe to run my SVP at near death gain, and not have it break in any shape, since it has tubes and all? And are there any specific tubes that can handle higher gain, and are cleaner at higher gain? I am also planning on buying an Avatar 410, in addition to my current 410. And running one cab clean, one overdrive. But I figured that if the Avatar is good enough I will sell the BSE and just keep that one. BTW, all of this will be controlled by an A/B box to switch between channels. And also, I will run both pre's into my compressor too. Any tips for better SVP tubes, or any other tips or suggestions?
