I'm writing here to ask for advice on a guitar of mine.
It's a factory-built 8 string fan-fret design (There's only one company that does those so you can guess who it's by).
Once I started playing it for a while I noticed some tuning issues, and eventually my eye noticed that there were a number of frets that were out of line. I had a back and forth with the luthier and he agreed to pay for that to be sorted, as it would otherwise have had to be sent across the world and back. I found a guy in London, and he took out and realigned a few frets, as well as adjusting the nut and bridge, which definitely improved things.
However, I'm still struggling with the intonation - I've measured it, and I'm getting about +30 cents on the octave on most of the strings, but especially the trebles (I string 4 basses and 4 trebles, like a 'Brahms guitar', and I tune like a renaissance lute - ADGCFADG). My ears really can't take the instrument being that out of tune.
I suppose I need the thing serviced properly, so my query is whether there's a luthier in the London area who'd be willing/capable/available to have a look - it could need just more nut adjustment or it could require further re-fretting etc. The guy I used before was good but was more of an electric guitar specialist.
If anyone has any advice or recommendations I'd be grateful to hear them.
