Hi all, The Sire's fretboard radius being 7,25" I have a noticeable string inbalance (weaker D and A) especially on the bridge PU (the stock one).Unable to correct this,no matter what I tried during the neck/PU/saddles setup. As I don't mind a hotter bridge PU than the stock one,I might opt for a pair of Nordstrand BJB4 (JB blades - the W&W variety) ....their blades are radiused but I didn't find any reference about the radius' value on these PUs. Does anyone here use Nordstrand BJB4's on a 7,25" fretless fretboard?If yes,does the BJB4's solve the string (in)balance? THX! PS Question no. 2:does anyone know what's the BJB4 W&W's DC resistance?
