I disconnected the negative feedback loop in my 50watt plexi superbass and adjusted some of the cap values in the preamp and yes it sounds massively alive and 3D.I did the same with a blackfaced 40 Watt Bandmaster Reverb and that was improved hugely too. Strangely enough though I tried the same with a Twin Reverb and didnt have as good results and a 100 watt superbass wasnt as immediately as impressive, I had to experiment a bit more with the preamp values to get it sounding good, but it sounds awesome now and I wouldnt go back to the NFB set up.
