As I've been a fan of Markbass stuff for a while now and also play lots of rock/metal so this amp has my interest. Not sure what to expect from the tube drive (tests will tell on that) but is anyone else surprised at the lack of the VPF control? I have always found the VPF much more usefull in getting a rockier tone than the VLE, if not offering both it seems to me that its got the wrong one. Anyone else thinking this? I am merely speculating but I see this as a potential silly flaw.
