I have a problem with durability of strings having somewhat acid sweat.

I've been using Elixirs, which I like, for several years but they are too expensive for me, despite the fact they last longer. I have, therefore, changed to using Newtone strings on all my instruments. These are individually made made Malcolm Newton in the UK and he supplies the custom gauges I need. I just got an order of 12 sets in the other day. Malcolm uses good quality alloys and winds his strings on round, rather than hexagonal, cores which also improves their corrosion resistance as there are no "pockets" for moisture to build up in. I find his strings last very well and sound excellent.

His site is here

Newtone Strings

for anyone who's interested. He does take credit cards and will do mail order. I believe 12th Fret in Toronto are a stockist.

Peace,
