It has been cab-o-rama here for the past couple of days - my cabs came out of storage. A 1X12 Avatar cab with an Eminence Delta Pro 12A - similar to an EVM 12L - and a Marshall 18w style 1x12 cab with a WGS Veteran 30, both open-back. I played my Princeton non-reverb and stock Tweed NOS Blues Jr. through the cabs. Strat or Tele into compressor, distortion box and delay, or clean. Turned everything up. Big fun. Both amps were unexpectedly - and pleasingly - loud when each was run through both cabs at the same time. Since the rap on Blues Jrs. is that they sound boxy due to the small cab (and how the amp is constructed) I ran the Princeton into Blues Jr's. Jensen C12N to hear how it sounded. Revelation - the C12N in that small cab did not sound boxy, honky, choked or constrained at all when hooked to the Princeton. Nice firm lows, good mids, and not squishy or weird sounding. Good cleans.
