yeah, that's right. I removed part of my gloss and now my guitar is matte.

it's a GSA 60

I read up some old posts from the forum and couldn't find much on sanding the gloss, so I took some advice from Blackmoo and got down to work. The results was a matte, almost dirty looking guitar. I sanded everything, the gloss, all chrome parts and even the head.
pics are in the gallery: http://www.kbase.com.sg/gallery-gjkung/index.php

for those interested in doing something similar, here's how I did it:

Tools:
Gloss Matting:
Fine Bronze Wool(http://www.steelwool.biz/Bronze_Wool.htm)
Scotch Brite(http://www.3m.com/us/home_leisure/scotchbrite/)

Metal Scratching(dry sanding):
3M 360 Imperial Paper
3M 400 Tri-M-ite Paper

Cleaning:
Water
Spectacle Cloth and cardboard to scape off bronze dust and water mixture.
Vacuum Cleaner on High, equipped with brush/hairy nozzle.

This was a very simple and tedious processs of scrubbing the gloss with scrotch brite and bronze wool, scotch brite being the coarser one and bronze wool for fine finishing. remember to keep to a constant direction when scrubbing, or else the scratch lines will cross and make your matte look like a real accident. just keep going in the same direction with patients and wait for your gloss to slowly blur out to the desired finish.

then vacuum the surface with the brush nozzle, very important if you don't want to scratch your guitar. when surface is clean, moisten cloth very very sparingly and just wet-wipe in the direction of the scratch pattern. Make sure the moisture level should be just enough for the water to evaporate seconds after the wipe. Do not wet your guitar.

For the metal, just use imperial paper to sand your metal surfaces, if the feel is too rough, soften it down with Tri-M-ite paper. Imperial paper is coated with Alumina(aluminium oxide) which lubricates the sanding process, gives a very smooth finish.

That's all, just repeat the process and go along your guitar slowly, don't try to rush or you'd end up destroying the gloss without getting a proper matte.
I won't say my guitar is done, cuz I'd still like to polish the matte a little, maybe with emery paper. but looks pretty nice now, it's all grungy and personalised, all the tuning pegs and vol/tone knobs are all matte now.

parts sanded/scratched:
Jewel Blue finish/gloss
SAT10 tremolo
pickups
vol/tone knobs
head
tuning pegs
neck (slightly scrubbed with worn out bronze wool for smother feel)

that's all, if you want o know more, please PM me or post your questions here. feel free to say I'm an idiot for doing this.
 
No, you are not an idiot. Its cool man.

Anyway, consider getting some fine sandpaper, go to those Hobby Shops and try to find 1000 grit and then 1500 grit and maybe 2000 grit.

These will help you smooth out the finish even more.
 
thanks dudees.

btw, I forgot to mention that it's better to use bronze wool and not steel wool because it does not rust that much, bronze dust doesn't stick to your pickups and steel wool dust will rust and discolour your surface.
 
xspace, I don't know.

take a look in the gallery and find out, cuz i don't know what "this one" looks like in real life.

hey gjkung did you use the bronze wool together with water for wet sanding at the same time? i read somewhere that this helps to keep the finish even? ur post indicates that you only apply moisture after the initial sanding was done with dry bronze wool..
 
yeah dry bronze wooling

I didn't want the bronze to rust or anything, even though i wasn't sure whether it will rust in the first place.
 
yeah, easier to slide and all.

Also, now I don't need to worry about my gloss being clouded by the oil and sweat from my hand. :D
