Re: Choice of two
I've got the DSL401K, its my main gigging amp, in the small club scene. It has two speaker jacks, so you can run extension(s) and or the built in speaker. its also got the speaker emulated DI out, which is a nice option to micing the amp, and sounds pretty good. Its got an FX loop too, but I never use it. The master volume is nice to get those preamp tubes humming without being too loud.
I like it. It doesn't have a lot of headroom on the clean channel, it'll break up before it gets very loud on the clean channel, but its a nice bluesy kind of break up. The OD channel is also nice, and it can go from classic sounding, with gain around 5, to pretty saturated at ~8. It can be a bit bright, so I keep the treble lower than the bass or mid.
I've been using it for about 10 years now, 50 or 60 gigs a year, and practice, and I have had to have it serviced, including the soldering for which I think its notorious. It didn't seem excessive to me, you're going to have wear and tear with a working amp, aren't you?
