Mesa TA-30 amp head vs. Carr Slant 6v amp head. I'm using a Radial Headbone head switcher to toggle through these two amps. They consequently are both running through the same cabinet of speakers, which is one Jensen C12N and one Weber California. Because of the radial switcher and the footswitches corresponding to both amps, I'm able to get 4 footswitchable tones at my disposal. Using the same speakers, it's pretty amazing how similar these amps can sound to each other. Plus, the way I've dialed them in to my personal tastes for 'useable' gigging tones for my purposes, there are absolutely no pedals needed. I just plug into the Radial's buffered input straight from the guitar.
