I've been in touch with a number of purchasers who've had very shoddy treatment at the hands of kvh-music. Items take weeks or months to arrive, and sometimes (as in my case) don't arrive at all.

The seller claims to be in the UK, but all the items are shipped from US (if they are shipped AT ALL!)

The goods which I bought (at a cost of just under £40 inc. shipping) never arrived, and kvh-music are completely ignoring all of my messages, my paypal dispute and my ebay dispute over the item.

It also looks suspiciously like the machine heads I bought were actually taken from a guitar returned by another disgruntled purchaser, which arrived broken. That purchaser doesn't appear to have got satisfaction either.

AVOID this seller.
