I've used the heads a couple times, and I've liked the way they sounded, the old K200s. I've never needed to dime them, but they sound good for an old SS head. I think the weak link was always the cabs. Stu Cook in CCR used the heads, but paired them with the Sunn 2000s cabs, which I've done as well and the heads hold their own. That said, I'd rather pair the 2000s cab with the 2000s head. And If I'm playing SS I prefer an Acoustic. But the Kustom Tuck and Roll is still a fun old amp.
