Here's an update on my CV60s PBass upgrade progress. After reading Zenrad's excellent posts and photos on bridge and finish mods, I decided to tackle the same thing for mine. On the bridge front, I went with a Fender Vintage style with threaded barrels as he did. Project was fun but a bit tricker than I anticipated in a couple of places, mostly due to me own lack of experience in this area. I've very comfortable with any electrical work and have gotten good with truss rod and set up tweaking but less so with wood work. I bought a dowel to stuff the holes and found that it was too large so whittled it down to fit. Worked OK but would recommend with Zenrad did which was to drill the holes larger to fit the dowel correctly. My holes came out OK but I was less worried about it looking good since it's under the bridge. Tricky part for me was determining correct location for holes. The vintage bridge is narrower than the hi mass Squier one so you have to get it just right in terms of left/right position so the old holes aren't visible. I used a piece of masking tape to hold the bridge in place to get correct position. After I lined it up, I lifted the bridge to put another piece of tape on the body for drilling to minimize cracks on edge of holes. The bridge lined up nicely and covered all but a fraction of the holes, probably visible only to me.
Zenrad had mentioned a difference in the tone with the switch an I can confirm the same on mine. I was frankly surprised given the trend towards hi mass bridges in basses and the fact that the Squier bridge actually has brass or at least brass colored bridge pieces. After some rough adjustments, the difference was apparent right away. Much fuller sounding in the bass and just overall felt more solid. Also, and can't yet confirm this, seems like I'm able to get the action even lower than before. Maybe just because I haven't done a full setup yet.
My basis for comparison for tone comparison is my AV57 PBass. Swapping the very good sounding Squier CV pickups for some Fender Originals got some of the way there but changing the bridge sealed the deal. My Squier now sounds like a classic PBass and I can't stop playing it!
Part of what inspired me to go ahead with the mod came from spending some time with Jim Coppolo of Alleva-Coppolo basses. I played several of his amazing basses at Bassplayer Live and also chatted with him. He installs either a high mass or very nicely made Fender style bridges in his very expensive basses and explained that the Fender style bridge works best if you're going for classic Fender tone.
Highly recommend this mod/upgrade. For $35 and a couple of hours really does make a difference. If I were to do it again would of course take half the time.
I had also planned to dull the finish as Zenrad had done since I love the look in his photos. I bought grey scotchbrite, 000 and 0000 steel wool and polishing compound. I did the area under the pickguard as an experiment and wasn't happy with the results. Even with the steel wool and polishing compound it just looked like a badly scratched finish. Maybe I went to far on with the scotchbrite or maybe more polishing is required. I'm sure there's an art to getting it to look right. Any tips would be appreciated.
Lastly, I switched back to the original CV pickguard. The 62 RI one has better looking tort but it left a small gap near the output jack on the bridge side of the guard. No way to realign it to fit so went back to stock one. Had no trouble refitting with Fender Original pickups and covers installed.
