I've recently bought a CA6 and a PB-1 to go with my Schroeder 1210 and this is my first separate pre / post attempt. Is it going to be a problem sitting the pre on top of the amp on top of the cab without any rack or space between them? Will the amp over heat the pre or vice versa? Will the schro's carpet catch on fire? (only partially kidding about that) It's tough to find a decent rack that'll fit in Australia, so for a little while I'll be rackless... While I'm here, I'm hoping there won't be any problems bridging the CA into the Schroeder? My current amp is only 250w so this be a decent step up hopefully Cheers!
