I found Markbass to sound fairly “meh” isolated but in the mix they sound great.
I bought my old set up as every time I heard a covers band in pubs where the bassist had a good tone it seemed to be a Markbass rig.
So when I got it and set it all up at home I was a bit disappointed, but once I got to rehearsal I realised where its strengths were.
I generally had the VPF on full though.
