I'm looking for a high gain(maybe) 12AX7 for V2 in a Peavey Classic 50. Right now I've got a high gain JJ ECC83, but am not to thrilled with it. I've also got a JJ ECC803 in V1 which sounds great on the clean channel, but I think it might be hindering the overdrive channel a bit. Right now the overdrive seems a little buzzy. It doesn't sound bad by any means, but I'm sure it could sound better. I don't have a specific tone I'm going for, just a good classic to hard rock distortion. I use a MXR ZW-44 in front of the overdrive for the heavier stuff (great pedal btw). So, could ya'll give me some suggestion for a new tube?
