I believe it gets no finer than this. Ultra high end Class-D amplifier and 1-12" cab. He could likely provide this with the appropriate JBL loaded in it or maybe sell without speaker. I use this for pedal steel. 29lbs, 300 watts into 8-ohms, 500 watts into 4 ohms.
A few facts I'll add:
1) TC is a super nice guy. Brad told him to expect a call from me, I did, we met, shook hands, 10 minutes later he let me take one to test out.
2) The SPLIT sounds amazing. All the portability and volume of a powered main/monitor but sounds like a guitar cab
3) It's so frickin' light it's amazing
4) Build quality was wonderful!
