I'm a big fan of Kustom Amps.
Ten years ago, when I was teaching at a local music store, I had a chance to try all of their amps; Kustom, Marshall, Fender, Peavey. In side by side comparisons, I thought that the Kustoms sounded the best.
I bought a KG10, that I've donated to church. Ten years later, it's still working, without so much as a dirty Pot.
The American made, James Brown designed, '36 Coupe, is my all time favorite amp. Since getting the Coupe, I have sold my Blackface Bandmaster, and Musicman RD50112. They were my main amps for over 25 years. I've also owned an early Tweed Deluxe. With a speaker change, I can dial-up Tweed, Blackface and Marshall sounds. I have also owned a '72 Hardtop head. I've never had a problem, with either amp.
The newer, Chineese made Defenders, are also pretty nice amps. I have owned a Defender V15, for about 3 years. The amp comes with a good Celestion speaker. The tubes were the only thing that were in need of upgrades. The only problem that I am aware of, with these amps, is the Bass Response switch. When mine got dirty, I was able to clean it by switching it back and forth, a couple of times. Others have returned their's to Kustom, for a replacement.
