Done a bit of research and it seems I'm not the first person to have thoughts in this direction (that would be unlikely!!) - see this beautiful hack job. https://reverb.com/item/71447082-fretle ... lack-relic

but there's definitely nothing out there as far as I can see that just exists to buy. I've come up with a few options:
1. Get an electric tenor guitar / mandolin (Eastwood being one obvious choice here but presumably not exclusive) and remove the frets. Relatively straightforward, it's already set up for roughly the tuning I want (probably either viola or cello tuning, or 5ths tuning somewhere in the middle of the two). Seems like a winner, the eastwoods are more expensive than I thought but maybe a bit of hunting will turn something up cheaper.
2. Get something custom. For example on my travels I found this: https://alphershop.com/products/micro-m ... eq=uniform this is spookily close to what I want, just WITH frets. And presumably there are other people that would do something. But, relatively expensive and probably a fair wait.
3. Get a short scale guitar and swap out the bridge and nut for 4 strings, remove frets. Bit more work than option 1 but still doesn't sound toooo crazy? (though finding a bridge with the right spacing might be interesting... Need to look at the "weird guitars" and see what spacing they're using). But feels like more of a gamble with it feeling good with the 4 string setup - principally thinking the neck is going to be bigger and that might be odd.

Anyone know anything I don't, got any inspiration?
