TL;DR version: I've got one and I love it.
I've had a five-string ash-bodied maple-necked 1st generation V7 since just after they were originally released (2015 was it?). I sold a wood-necked Status Series 1 in order to buy the Sire and have not regretted that move for a second. And the Status was a wonderful instrument. If the V7 and P7 had been released at the same time I'd have bought the P7, because the P pickup suits some of my needs better, but that's by the by.
Apart from the ramp you can see in the pic, I have made four changes:
Entirely aesthetic... I replaced the placky knobs with some chrome ones, easy to source on fleaBay.
Fairly essential... I replaced the tuners (which were pretty ropey on the early gen1 V7s) with Hipshot Ultralites, which not only made tuning more precise but also shaved a whole half a pound off the weight, which is in practice a lot more than it sounds.
Also essential... I replaced the bar type string-tree with a pair of Hipshot retainers. The bar was absolute rubbish.
Purely preferential... I have recently replaced the original bridge (which was little more than a BBOT) with a top-loading one, and blocked off the through-body stringing holes. This is because I never strung through the body, always through the bridge, and I hate having to thread strings through holes in the tailpiece, I far prefer quick release slots. This new one also has screws to lock the saddles in place, whereas they were floating on the original. The standard string spacing on the V7 fivers is/was 18mm, this new bridge has extended that to 19 which I do prefer. I never felt particularly cramped by the 18 spacing but I wouldn't have wanted it any tighter.
I found the QC to be absolutely perfect... all the inlays were perfectly flush, the fretwork was neat with no sharp ends of any sort, the control cavity was neat (and very full!), and the finish flawless.
I like the standard EQ, a lot. Some people don't, "too many knobs!", but I like to have plenty of control available to me and this delivers.
Some people also think the headstock is fugly, and while I'll admit it's not exactly glamorous, it does remind me slightly of Sadowsky, which I'm perfectly ok with.
If I had to pick on one thing that I don't like, it's the weight. With the lightweight tuners fitted, it tips the scales at 10lbs 3oz (4.6kg), which makes it quite a lump to lug around -- nearly a pound heavier than my Shuker and well over 2 heavier than my Spector.
Bear in mind that this is a very early 1st generation V7. The 2nd gen ones have addressed some issues -- by all accounts the newer tuners are faaaaar better than these were, for example. Apparently the rolled neck edges on the new ones are incredibly comfortable, and something I wish mine had.
If mine was stolen, I would absolutely buy another, but it'd be a P7 this time.
HTH.
