What's happening when I am using: Realtube II preamp~>Behringer comp~>76 Twin Reverb. I found last weekend that when I had the TR input volume on about 7 and the master on 10 I was getting fantastic tone just by varying the output gain on the preamp and/or the compressor (but mostly the guitar volume knob). So basically the Twin was running almost wide open. Are there any negative ramifications to this? Is this the best order for the signal chain?
