Good find, Pete.
I’ve been leaving the amp on all of the time – it’s draws so little power.
The reviewer and I the same experience, including listening to Hole Cole’s Temptation. And I also listened to Harp music and noticed the same details mentioned about the guitar characteristics. He has much better writing skills then I do so I won’t further comment on the amp. As I stated previously, if you have tubes in front of it I think you’d be in great shape.
I don’t know why this thread keeps getting drawn back into a “break-in” debate, but that should be done elsewhere. I didn’t before I got my Esoteric SA-60, but even they (TEAC) recommend break-in, and in fact, an IsoTek CD designed to accelerate it.
