I have a falcon jr that has a headstock break that I've been looking to get fixed for a while. Seems most luthiers in London are either too busy or just haven't gotten back to me, but two have: Tim Marten (Denmark street), and Feline Guitars (Croydon). Has anyone ever used either before? I'm currently torn between the two. Tim Marten seems like more of a known quantity, has more info available etc, but I can't get past a couple of reviews I saw online that said their guitars were returned with new dings. Feline guitars' reviews are impeccable, but their website (https://felineguitars.com/pages/price-guide) doesn't really mention more involved work, which also makes me nervous.
