hey all, I recently saw these SX basses and heard they are a pretty good base for mods (i.e. replacing hardware and electronics). since I'm looking for a fretless and a backup bass and I cant afford another Warwick, how would these fare in terms of playability, reliability and fret work? can drop-in fender aftermarket stuff work here without drilling and routing (schaller tuners, Badass bridge, direct replacment fender pups etc.)? TIA.
