PG's On Location at the 2010 Summer NAMM Show where we get to check out 3rd Power Amps American Dream 1x12 combo. It includes a Brownface channel, Blackface channel, switchable tube output power (22w/10w), Bright switch on each channel, and global Presence control. The amp also features 3rd Power's proprietary Switchback triangular speaker enclosure to deliver room-filling sound while isolating the chassis and sensitive tubes from vibrations originating with the speaker. It comes loaded with a Celestion Alnico Gold speaker, 2-winged C 6L6GC tubes, and 1-12AT7, 2-12AX7 preamp tubes.
