Oh my.......I've actually started selling my old basses already , if they sell before this goes, I'll be planning a trip down from Glasgow. Beautiful bass !!!!
Pretty rare they come up. Gamut make nylon wrapped G and D's now. I've had their plain guts and they were amazing strings. I think velvet still do a wrapped gut G too.
Take a look at the Gutalike swingmaster set if you're set on getting Gutalikes. The G & D strings from Gutalike are nice strings. They sound and play very like plain gut. Not quite as much top end and not as much give when digging in.
The plain A string is actually ok. Good fundamental that carries and projects quite well. The swingmaster wrapped E and A do away with the "dead" bottom end. Still sound like gut, but much more pitch. You can find them on YouTube for sound samples.
Vintage revolution acoustic box live mate. The gen 2 box is out soon or even now. You can still order the gen 1 from loopers paradise. Ron Wouters on FB upright union has one.
I can Recommend both the string and the seller a high quality gut string. I bought one of these a while back, very well finished, great tone and playability. GLWTS.
