First off, thank you so much. You're a great help and I really apreciate you sharing your knowledge with us. Thank you.
Now, I use a Carvin Nomad. 50 watt, 1x12, 5 12AX7s, 4 EL84s. I love the overdrive channel, it's real crunchy and can go from a good, transparent, slight overdrive to full on metal crunch. I really enjoy the dirty channel but the clean breaks up real fast. Even on practice volume (loud, but not painful) it tends to get a little distortion. I was wondering if there were any tubes (I'm not sure if I need better preamp or power amp tubes) that stay a little cleaner but can still get some good crunch.
