Thanks for the advice. I think I'll buy a metre of cable as I'm rubbish at wire stripping and reterminating and all that jazz. Should I use the same cable, or could I get away with cheapo? And if I'm using cable for one, should I replace them all so that they're the same, or will it be fine as is?
Wire is usually better than bars anyway. You get very little contact area with many of the designs we see. Wire deforms to fill the space better.
Being such short lengths gives very little time for the wire to impress its signature upon your sound. The above advice is very good, but if you use something a bit different then i doubt you will notice tbh.
edit: ebay ofton have gold plated copper or brass wire if thats any good to you. People use it for making jewelery and stuff.
