Not sure what Imeo uses for the ready-made wires, but I believe the nickel NR wire sold by resellers is 32ga. Back before the ready wires were available, the GG attys would come with a small length each of R and NR wire, which at the time was 34ga nichrome and 32ga nickel, respectively. Perhaps he still uses the same wire for the ready-made, but I don't know for sure
Hmm. It could be 34 still. I measured it over the last weekend and now forget.
