Metro Amps is groovy... in fact, back in 2003-4 I installed a Metro JTM45 point to point board in my JTM45RI (my main amp).
Dealt with George many times and he's a cool cat. :icon_thumright:
If anyone goes this route, I highly recommend going NOS for the t00bs if you want to be as exact with the tone as possible (most new manu t00bs suck ass).
