Just arrived today. Can't wait to get home and try it. It's the older style with the switched effect loop and dual 500k master. I plan on switching it to the newer style interrupt loop and larmar master.

Clips coming soon.

I also love this amp, with the master volume you can dial your volume for bedroom playing (even with a 4x12) or stage volume when you need it. It gets VERY loud fully cranked and possibly too loud on stage too... This isn't like other amps like 18 watt where power amp distortion is needed for good tone, it's like a JCM800 where the sound comes from preamp and power amp distortion is typically f----ing loud, so the master volume works great. The in between is great for blues and cleans are good enough for church or jazz playing. The cranked tone can be used in modern metal however for that ultra high gain you'd need a pedal.

I just installed the larmar and an interrupt loop. They both sound better than the regular master and the non-interrupt loop with the switch that was in there before. The larmar master sounds better than an attenuator or power scaling IMO.
