This is a Bobcat from Denver Amp Works. This is the model they made for Brad Paisley and he used on Wheel House, only difference is mine has an added digiverb by Belton. Same company makes FluxTone speakers. It's based on a 5e3 circuit. The speaker is their version of a Celestion alnico blue. True PTP hand wired. The speaker can also be used as an extension cab for other amps. Spent about 6-7 hours with it yesterday and was quite impressed. What's the big deal? The big deal is the speaker - you can turn down the magnet strength of the speaker. What that allows is for the power tubes to be at full blast while the sound level is lowered, but without putting a load between the output and speaker. Very cool concept, and it works. The Belton digiverb ain't fooling a 'verb addict like me, but this circuit never had 'verb in the first place and it's nice that it's there to put some air around the notes when wanted. Also responded very well to pedals. So fun to crank this thing and have the same feel at a volume that is appealing to the wife!
