Marshall bass gear has always lived in the shadow if it's guitar oriented brother.
I have not played a Marshall bass rig that didn't sound good. Granted, on some I had to play with the eq a bit, but solid and clear nonetheless.
Whether it's the ibs, DBS, super bass, 800 series, mb, or vba, I will always be proud to play through a rig that sounds as good as marshall's.
I will never understand why they decided to knock the Marshall bass brand in the head though, the Eden stuff just doesn't sound as good to me.
I doubt I will ever get shot of either of my DBS heads.
