Today is "Boogie Reconfiguration Day". (The Super Dallas is perfect, so I'm not changing a thing on it) Lugging a small 62lbs. combo has pissed me off for the last time. So out came the head shell. If I could remember to mount the fan before installing the amp, it would have taken 10 minutes to complete, but nooooo. :L Anyway, while things were apart, it was time for a tube roll. Out came V1, V2, and V3...a M/B SPAX7, M/B 12ax7, and Tung Sol 12ax7 respectively. In went all NOS...RFT 12ax7, Baldwin-labeled Sylvania 12ax7, and RFT 12ax7, again, respectively. Dybbuk made sure I got it right.
The amp instantly dropped 30+ lbs. and got a great tonal colonic. The RFTs are a great way to warm up a bright amp. The MkIII uses V1 for ch1, V2 for ch2 and V3 for ch3, so you can see that I reserved the Sylvania for making ch2 a little more Fender voiced. Channel 2 cascades V1 into V2 so the flavor of each tube blends with the other. It makes for a fantastic pedal platform. Channel 1 remains beautiful but warmer and articulate. Ch2 can influence Ch3 if I keep that switch on w/ ch3 is engaged, which adds even more gain (as if you'd think that was possible). So warming ch3 takes the harshness right out. Plugging into my PRS 1x12 w/ a 16ohm V30 allows me to push the master a bit harder without destroying everything in the house, which is nice. In all, it's a great change of pace.
