Re: Show your Squier Mascis JM Mods/Improvements!
I've done some mods to mine.
Black pickguard, new pickups, slightly aged white covers, AVRI trem. Also bought a Mastery bridge, but in the end put it on my Bass VI.
Couldn't be bothered to re-drill the holes for the thimbles...
Instead, I filed off all the sharp corners on the TOM. I also widened the slots on the TOM and filed the saddles down to the proper 9.5" radius.
Plays and intonates perfectly. Stays in tune perfectly even with wild trem usage.
I also liked the satin finished neck but made it even more smooth by oh so slightly sanding it with 800 grit sandpaper.
Put on chrome dome knobs - these are so nice when doing volume swells with your pinky!
Re-strung it with D'addario 11-52s. My favorite strings at the moment.
Here's a somewhat crappy picture.

Right now I'm still fine-tuning the new pickups. I will post some sound clips before and after in a separate post.
I got the pickups from Shawn (chnlone) and can already confirm: They are really nice and worth the upgrade.
This guitar is GREAT! It was very nice stock. But now... definetly a keeper and my #1.

Where did you find the black guard that will fit the JMJM? I'm wanting to do that too but can't find one that isn't made for MIJ.

I Put a tort AVRI guard and a wilkinson roller bridge. I thought about changing the trem to an AVRI one, but didn't find the need after the bridge upgrade.
Next step, a proper bone nut. I have no plan to change the pickup as I really love them.

Re: Show your Squier Mascis JM Mods/Improvements!
Here's mine:

All the electronics, the pickups (Mojo pickups), the pickguard and the bridge have been changed. It was a great guitar, it's now a killer guitar !

Re: Show your Squier Mascis JM Mods/Improvements!
Have you redrilled for the new bridge thimbles?
Was it worth the effort? Is there a lot of hearable difference between the two bridges?
I only tried my mastery with it, but I didn't re-drill.
I simply wrapped the mastery thimbles with some adhesive copper tape, as tight as I possibly could and then fitted them in the bigger holes. My observation was that a properly installed TOM sounds better than a somewhat wiggly fitted Mastery.

I didn't redrill, I used scrub screws in the TOM thimbles, following JforJag's clever idea:maximee wrote:Have you redrilled for the new bridge thimbles?

Yes it worth the effort IMO, I find the guitar now sounding more jangly.

@shaggseb...was the wilkinson roller a direct drop in? seems like a cheap mod that's worth the effort...

Yeah it was a direct drop in. Remove the TOM and the studs, put the new studs in and place the bridge, DONE.dinosaurkale-> wrote:@shaggseb...was the wilkinson roller a direct drop in? seems like a cheap mod that's worth the effort...
However, all I had to do with the new pickguard is to sand the bridge's holes a little with sand paper in order to lowered the studs at their maximum, since the tort with its 4 plys is way more thicker than the anodized one.
But if you stay with the original pickguard you're fine. I'm a heavy tremolo user (à la shoegaze) and the guitar stays in tune beautifully and the tremolo use is way smoother.

Re: Show your Squier Mascis JM Mods/Improvements!
Sorry to send the thread in a slightly different direction but....
I really want to replace the bridge on my j mascis, and came across this 'wilkinson ultimate roller bridge'
It seems to have adjustable radius, which is a big bonus.
Would this work as a replacement? Am I missing something, like string spacing or post spacing which would make this unsuitable?

It is about half way down the page on the above link
