Was just doing some random surfing and found that back in 1998 DOD made a tube / hybrid guitar amplifier (112 Combo). I doubt they made too many.
Here's the info that I found on it:
The DOD G112 is a MOSFET-power, 60-watt guitar amplifier featuring a two-channel preamp section loaded with the FX69 Grunge distortion, chorus, spring reverb and three-band EQ. The G112 contains a 12-inch Eminence speaker, two independent inputs (high and low), connectors for footswitch, external speaker jack, headphones line/out and DOD's jam-a-long jack.
The DOD G112 list price was $399
Here's a photo:
Anyone ever see these before?
