Feel is absolutely amazing! It feels both light and rock solid all at once. You can feel every vibration resonate through the thing. Neck is silky smooth under the hands, board is pretty wide and flat, which is not my preference but the way it feels sort of defies my preferences. It is a really good feeling instrument, among the best I've played.
Now for sound. It sounds great, but it took some getting used to for me. Black label is what are in my VM5, but the Delano's in my VM4 were similar. The pickups have a lot more dynamic range than I'm used to along with a bunch of top end bite. That all sounds good and desirable, and it is, but it also requires adjustment. I like pushing into the front-end of the amp and getting a full ballsy tone, which you can definitely do (really well) with the VM5, but you have to push it way more than might feel natural.
On it's own it is very clean, crystal clear, and the passive or active as the Glockenklang pre is pretty transparent. It has a lot of power and oomph, but to get to it (or get it to stand out rather) you have to mellow down the the top end a bit. Of course, that is pretty easy to do either with the onboard controls or outboard. I suppose the key thing is, it gives you a bunch of stuff you can easily take away if you don't want it (i.e. high end clarity) but could not easily add to a bass if you did want it.
Now, that is my take and I am not a gigging bassist or anyone that could be considered any kind of expert. Despite what may sound like I'm being negative about the sound, it is my favorite bass by a decent margin. Much of that is due to the build quality and feel, but I do appreciate that if I want crystal clarity (though I rarely do) I can get that out of it and otherwise I simply turn some knobs and have super powerful, responsive, attack heavy sound.
