Oh yeah. Common problem - Arjun and I
discussed it a while back as he has problems with his back - he plays an Ibanez S-series because it is relatively light. Parker Flys are the ultimate in low weight, but the real ones are pricey.
+1 on the wide strap. There are special straps from Planet Waves too.
So to sum up, you're looking for a lightweight comfortable guitar with a fat sound?
How 'bout
this? If I can sell it today or tomorrow, I'll sell it for R4K - there's an amp on special until tomorrow that I'm jonesing for.
Otherwise, after that I'm not selling. Stratlike, but even smaller and lighter body. Thin, but not ridiculous neck (21mm at the nut). Pickups are high output noiseless single-coils (which alone sell for R2,800). It's got an extra output jack and a battery compartment not being used this week (I had a piezo system in there and may again if I keep it).
