Built with a 6L6 power amp and 12AX7 preamp, a contour control to compensate for room and rig changes, and Bright/Boost/Deep pull control for even more EQ control, the Two Rock Studio Pro 35 Head is a modern classic redefining what perfect tone can be. Hand-built by master craftsmen, these little powerhouses are a paragon of boutique amp building and a known favorite of players like John Mayer. The perfect to bring along on quick gigs, this may very well be the last head you'll ever have to (or want to) buy.
