ANswer to your questions :
1. EH re-issues mostly sound nowhere near as good as the originals, some people out there can customize the reissues for a $, to sound closer to the oldies….
I have built an original issue 1 big muff (there were 3 different issues, most people prefer the 1st) replica, using authentic EH scematics & component lists,
it sounds much better than the sovtek reissue
very very close to the original (alternaTIVE TRANSISTORS HAVE TO BE USED, THE ORIGINALS ARE WAY OUT OF PRODUCTION)
if any you guys are interested i may custom build a few for a good price…
2. Most fender necks are a fair bit thicker than gibsons although playing both regular, i tended to bond with both after a while!
