Hi Ron,
I made the body to suit the neck, and the scale length is 25" give or take, and the intonation is spot on – I can set up guitars, I'm just not very good with wood or paint!
If I find a better piece of wood (some lime/basswood perhaps, maple sounds like hard work), I'll carve out a new body and try again. I actually really like that shape, and the neck is surprisingly forgiving, so it COULD be the basis of a half-decent instrument.
I think if I revisit it I'll more or less copy the SG pickup positions. The big problem is that flashy micro-tuning bridge, the whole setup is meant to give accurate and stable tuning even when you use the tremelo arm. Actually it goes out of tune as soon as you look at it, my brother ended up jamming a block of wood behind it and using it as a fixed bridge before replacing it with a standard unit, if I recall correctly.
I suppose now I have some half-decent metal-mangling skills I realise I could make a fixed bridge – I have an SG style bridge retrofitted to another guitar than I can copy, I don't like the Tele-style bridges much (that's a Squier tele in the corner), or just fit a new fixed backplate to that bridge. Either way a new body could be a bit thinner, I like light guitars.
As well as a banjo elsewhere, that's a banjo mandolin awaiting a second restoration some thirty years after my first attempt hiding at the back.
So many projects, so little time…
Neil
