Dont settle for a pre-soldered bleed when you dont know if it is best for your needs
Simple install
Try series or parallel to find the best option for your particular guitar and setup
There is a difference
Pre soldered bleeds may seem convenient, but you need to solder in place anyway. Why not og the extra step and find out which configuration works best by twisting in place, testing, and then soldering in place?
Youre going to have to solder anyway.
