To echo
@LP Freak 's post, I always find it a bit funny when people on forums talk about Friedmans "not cutting through the mix", while guys like Steve Stevens, Jerry Cantrell and many other pros don't seem to have any problem with that
...I also played with my bandmate's older gen BE100 live many times, no problems cutting through.
While I won't argue with personal preferences in terms of tone (I really like Marshall too), I'm convinced the "not cutting through a mix" thing to be 100% user error. If you're playing with a shit-ton of gain, and EQing your stuff with too much bass/not enough mids you're gonna be buried no matter what amp you play, you'd be shocked to see how little gain most guitarists actually use, even in metal scenarios.
I played through Mark Tremonti's rig a few years back (Bogner Uberschall/Mesa Triple Rec in a stereo setup) and the thing that struck me was the amount of gain he uses, not even close to what I was expecting, it's all in the picking hand/volume on stage.
Back to the BE100 DLX, it's got a lot of switches, and this means more tonal options at your disposal. It also means that if you don't know/care to know what each switch does, and how it affects the feel/sound of the amp (especially the frequency and response switches), you're most likely gonna get frustrated and blame the amp for "not sounding right", just my 2 cents!
