This might make for sense if I tell up first that my Warwick Corvette Proline is a 30" short scale fretless that I string with 4/4 cello strings and tune as a cello. That said, I have been noodling around on it for a couple of days, trying to finally wrap my head around this instrument I paid a lot of money for and which has mostly sat in its case for 11 years, and I discovered something. I'm posting this here, because it might be interesting to some people.
Interesting. I was watching the Break of Reality cover of the Game of Thrones theme again, watching Laura Metcalf's fingering, and I notice she plays the main theme on the A string. It's a very large jump from the 10th position to the 3rd position, but she seems to span it relatively easily.
Now, my instrument nominally has a 30" scale length, which is 2.5" longer than a 4/4 cello, making the jump 8.39", where on a 27.5" cello, it's 7.69", but then I just measured the actual scale length of my instrument, and it measures slightly less than 31"
, making the jump even wider. Measuring 27.5" from the nut would put the bridge in between the two pickups.
I may consider some modifications to this instrument in the interests of playability. A low height wooden jazz guitar bridge might work, especially if I tilt the neck back a bit and/or remove the bridge pieces.
