Do you mean the newer version, the DSL40CR?
I would highly recommend going for that. The previous DSL40Cs are likely being blown out to make room for the new version.
The previous DSL40C sounded good but had well-documented tonal issues, namely shared EQ between 2 channels that were impossible to reconcile, with Channel 2 being way too bright in comparison to Channel 1. A lot of folks then used it as a single channel amp, using either Channel 1 (a sort of JTM-type of vintage voicing) or Channel 2 (scorching hard rock/metal) exclusively.
By pretty much all reports, the current 40CR solves those problems and dials down the harshness/brightness of Channel 2, allowing for the shared EQ to work more evenly across both channels.
I think they are great amps when played very loud, they are ok without the power tubes saturated but that's where the magic is. The channels balance much better at stage volume, don't even need to do c19 in my opinion if you get cookin.
if you want to rely on the preamp for more modern rock a used jvm could be worth holding out for. DSL can do it but can be a little fizzy maybe.
The classic gain crunch mode with a boost when cranked is pretty epic I think but it was too loud for me
The JVM's are likely out of my price range. I'm looking at this one for a couple of reasons:
1: I have a Marshall cab but no Marshall amps
2: I like EL34 tones
3: This one came up for a song.
Then I think you can make it work, good luck and if it's not for you you can get back what you paid
I picked one up for $350 Saturday and I have no regrets. You should be able to sell it for $300+ assuming it's in even half decent shape in a few weeks if you decide is not for you.
