Just plugged into my new baby. Brian/Therdrail had taken this back in a trade for a combo, so it was a steal. At its core it is a 60s AC15 using vintage iron, chassis, and tubes (I filled it with a Tung-Sol 12ax7 in V1, a pair of Westinghouse grey plate EL84s, and a Mullard EZ81). But he replaced the vintage EF86 front end with a modified Matchless Spitfire dual triode preamp, and built a new head cab for it. I am in love, and don't see the honeymoon ending soon. Clean to scream with a turn of your volume knob. Can't wait to crank it up on stage into a full sized cab (I use a 2x8 at home to keep the dBs down).
