I want to mod my GBAs with clear sound... Is there any Pro-Sound mod or PCB for GBA?

Ok, I made a tumblr page to upload this image on my phone, so I can't link it but it should be under pugbath.tumblr.com. Basically, find the volume slider and the top points are your left/right outputs and use the case/side solder point as your ground.

Correct me if I'm wrong, but Gba should be the same as the dmg, right?

Nope. The amp is pre-pot. So if you solder to the pot you still have the amp messing everything up.
If you look up from the pot/jack area you will see 2 copper pads. Follow those traces back until you see 2 smd resistors.
Remove the resistors or just solder to the side closest to the CPU.
Sorry this is very badly detailed but I don't have an AGB in front of me right now.
Hope it helps!
P.S. No volume control.

My mistake, you are correct. I just uploaded a photo of the points described on my tumblr... They're pretty small, and I used the front side under the speaker. For volume control, you'd need a second stereo trim pot, or if you aren't planning on using headphones, you could desolder the existing pots and rewire it with your new points straight to the existing output.
