I've been using this cab for a while, and I really like it.
Its a hand constructed pine cabinet (made in Ireland), with a birch ply baffle. Its been fitted with a Celestion neodymium creamback, and I've also added a Palmer Junction speaker simulator. Additionally I've stuck inside the cloth a foam beam blocker.
I've fitted the handle on the side, so I can put my CF100 power amplifier on top of it. There are feet on the bottom of the cab, and also on the side opposite the handle, so its easy to put down on the train or bus.
The whole thing weighs in at 7.75kg (17lbs) so its very manageable.
It sounds great actually. The pine gives slightly boxy tone, in a cool way, mildly reminiscent of a Tweed Deluxe.
The only thing I'd change is to fit a more sensitive speaker. The Creamback is 97dB sensitive, which is has been fine so far, but I'd be happier with a bit more headroom. I'm looking out for a G12 Century.
