I have had a Trace V4 for years. I'm not a Trace fan, but the V-type amps are fantastic. The matching cab is a 2X15" which (not surprisingly) suits it perfectly. A friendly word of advice-as someone else said, I think you'd have no trouble selling that head if you split them up. Those cabs are plentiful and not so sought after.
Sorry to hear of you having to sell so much gear-that must hurt. Good luck.
