I have four sets of short-scale (30" scale, 760mm) roundwounds, bought second-hand a decade ago when I had something which probably fitted them - I never got round to it.
The Rotosounds, the La Bellas and the Newtones appear to be stainless steel. The Optima Golds are, um, gold? I don't know what the actual metal is.
They've all been opened; the Rotosounds and the Newtones have never been fitted; the La Bellas have been partly fitted (2 never fitted); the Optima Golds are cut 2+2 and there is some wear to the silks.
I have little idea how to price these so my preference is to sell them as a job lot.
£75 for the lot, posted, within the UK (outside the UK, let me know but probably there would be tariffs).
PayPal without charges (preferred), or bank transfer.
