The best 2x12 cab your money can buy. Hands down.
I have been playing guitar for over 10 years, and this is the most solidly built and customizable guitar amp cab I have ever seen, played, and owned! The price is outstanding for its construction and what it offers. I am running this cab through a JCA20HV and an extensive pedal board, and it delivers extremely solid and reliable tone and functionality. Built like a tank! The only criticism I have (and it is extremely minor), is that since you are custom ordering this cab, and because it is hand built, the wait time is approx. 3-5 weeks. However, it is WELL worth the wait.
Jet City and Doug White deserve all the recognition in the world for what they offer. I would gladly repurchase both the JCA20HV and the Modern 212 again if anything were to happen to them.
