I love both the vba and DBS series.
I've been a DBS user for many years now, and totally love the sound. The vba is gorgeous too.
The trouble is that Marshall have never really been accepted as a major brand by the bass playing community, despite there being a good number of 'name' players that have used them in the past. Such a shame. Since marshall's acquisition of Eden, I've not seen any on a live stage, let alone heard of any endorsers
Afaic you can keep your markbass, Aguilar, trace etc, and I'll be extremely happy with a solid Marshall backline.
