This idea came off the Jaco JPI website when someone posted about what 'mod's' can be done to a bass. It started me thinking about all the good and bad 'mod's' offered up over the years. So I started a list. It seemed back in the 70's when the 'mod-craze' started, players would own one instrument and do all they're mod's to it. I guess that's pretty well what started the 'mod' industry. From which came. 1) Dimarzio, Bartolini, EMG, Duncan, Fralin, pickups. 2) Who remembers the Fathead. The metal plate you'd screw to your Fender headstock to give you more sustain. As if a Fender bass wasn't 'neck heavy' enough. 3) Badass bridges 4) Hipstock D-tuners 5) Internal pre-amps. 6) Wammy bars for bass. As if guitar players didn't hate us enough. 7) The body guard you'd put on your bass so you didn't scratch the surface. Another way to insure it didn't get scratched was to leave it in the case. 8) The brass craze of the 70's. Those heavy brass bridges are worth more at your local scrap mental yard than they are on Ebay. 9) Different designs of bass strings. How about the piano wire design bass string. I put a set of those on my 66 P-bass with the original threaded bridge. Half way through the night the bridge cut thru the wire and sent the E-string hurtling out into the crowd. I didn't want to know where it landed. 10) Not to forget, Warmoth, Mighty Mite, Stuart Macdonald, Musician Friend. 11) The "Brass Nut" Who remembers what?
