I have a K-150C-8 I believe came out of a 4X10 combo amp at one point and is now sitting in a Kasino U-100 head case. I used it for a while till I got a K-250. It drove a 2X15 Kustom cabinet loaded with Black Widows and I was well pleased, plenty loud and great kustom tone but not a K-250. The only thing I didn't like about it is the reverb. It works but, its real weak so I always used a delay on it but the rest worked fine ie=(Trem/Vibe) as well as both channels and all the controls I can snap some pics if your interested. I also have the K100-1 head in Blue sparkle that is killer with guitar on a 2X12 low watt speaker cab that I would consider parting with for the right price.
