I've had the V1 since inception and NEVER turn it off. I've surely noticed its enhanced treble response ('clank'), but consider this something that's available for those who like that sort of tone. For me, it's never been a problem to either dial it down as needed OR to compensate on my amplifier, for truly it is the interaction of VT>amp that can fully tailor the tone to your liking. It took awhile for me to back off of my 'normal' amp settings, and can understand how some users can get stuck with the idea that the VT is all to blame - it is a general tone gooser, and goosed treble will surely be more noticeable to most bassists, but there it is if you need it, and you can cut it if necessary.
I mainly use the VT as a tone shaper rather than as a full-on overdrive - usually keep 'drive' around 11 oclock for a bit of edge.
To add hairy overdrive lately I've been running an Xotic BB Bass Preamp
before the VT; I set the BB at a low gain/high volume, roll off a bit of BB treble, then mix the BB sound with my clean signal through a Boss LS2, my clean signal set at noon (unity) and the BB signal set at 7:30 oclock (= just a bit). This clean + BB mix then goes into the VT.
Here's the result recorded with my band when my Fender P with a DiMarzio Model P P/U is run through this chain, into the front my Mesa Walkabout, and into a DAW recording console via the WA direct out - There's a bass intro and a bass break at about 1:22:
