Man, great overview, thanks! I have a fender am dlx that has fralin single coils that has the j-retro dlx and my main bass is a Gadow 5 that has Nordy big singles with the u-retro dlx. That passive tone is one of the best that I've dealt with on an active circuit. I totally know what you mean about the upper mid snarl, man I love that!! I think I may have to give that a shot, totally respect your thoughts on that. Appreciate that.
