So I stopped by my local Marshall dealer today (they're open on Sundays).
I've really really been wanting to get a JCM 800 R.I. So I got to try one out today through a 1960B cab.
And there was a DSL 100 atop a 1960B cab right next to it, so I fired it up to.
I noticed that the JCM 800 has a more up front immediate response and tighter sound. The DSL 100 seems a little looser and more distant sounding.
I think the 800 would cut through a mix better the DSL 100.
The JCM 800 sounded a little harsher though. The DSL 100 had a smoother tone in comparison.
All in all, I think the DSL 100 does get the JCM 800 sound pretty well. I'll still never part with mine if I can help it!!!
But I LOVED that JCM 800!! This test I did today made me want one even more! It sounded GREAT!
Incidentally, if anyone's interested, here's a comparison I did the other day between my DSL 100 / 1960AV halfstack and my MG100HDFX halfstack upgraded with Warehouse Speakers Veteran 30's:
