Thanks @jharms80439! That's a great looking Elfin (love that fretboard) with crazy range...that of a 7-string?!
Yep, 1/2 step shy of a 7 on both ends (in a 5 string package)!
In 5ths, (7)R345789 runs lie under the left hand, 2nds, 6ths, 10ths & 13ths are one shift. I found 5ths easier as I “age”, but really started on a 6 in 4ths ~30 years ago and can still mostly play both, but any new material is 5ths only.
Mainly played 4s & 6s, & a few 7s for a while too. Never really was comfy on a 5 and had never owned one before this one. Found it almost impossible to get a good high B for a 5ths tuned 6. Hence why I went with a 5.
Found that a 6 in 4ths really aggravated my left wrist tendinitis. Short shifts in 5ths doesn’t. It’s even more comfy on a 4 with the range of a 5(+).
Fretless is where 5ths really shines though. I’m chatting with a Martin on a semi-hollow fretless build now. Just need to finish paying for this one before I commission the new build.
I’m heading towards a quarter sawn or flame Maple neck, understated but still figured Maple back & sides, and either spruce or redwood top, all with a medium-dark violin finish. I just need to decide whether it’ll be a 4 or a 5, I’m leaning towards a 4 though.
Also, unsure it I’ll go with an Elfin or Elfin Plus body size for a bit more acoustic tone. Frankly I need to spend some time listening to Allison’s (77stingray’s) YouTube recording with headphones. While that one is a true hollow and mine will be a semi, I think I’ll get a bit more of the acoustic tone with the bigger body - and a semi-hollow without all of the acoustic instrument hassles that go with living in Colorado and the HUGE humidity swings and the maintenance a true acoustic comes with.
FWIW, my upright is still a ply too. Terrific tone and great durability.
