The Newtone 'Aloha' strings are made specially for wood bodied Hawaiian guitars, and are gauged 15-56.
They are designed with a round core and will come to pitch at a lower tension than other strings, so they are recommended for higher pitched tunings.
I usually tune to D and lowbass G, but I've had these strings in E and highbass G on my 'Superior' weissenborn without any trouble.
A bit hard to find though (and pricey), so I order mine direct from Malcolm Newton in UK.
Edit/Ooops,- I just noticed you asked for highbass A, not lowbass.... You'll probably need some lighter strings for that.[This message was edited by Steinar Gregertsen on 17 September 2003 at 08:35 AM.]
