Bad Cat was started by James Heidrich, with some collaboration from the famed Matchless designer, Mark Sampson. Together they created the Hot Cat circuit, which is a high gain embellishment on the Vox AC15 amp format. The amp also has a fantastic sounding Eminence Red Coat speaker. With this amp you can see some signs of long term storage, with some embedded discoloration in certain places, but otherwise it's held up pretty well. This is a fantastic value for a well designed, well built, hand wired amplifier.
