Hey I dunno if anyone else uses a GBC here, but I wanted to share my new mod with you
I stumbled upon a few of those "bass mods" for DMGs and thought about applying something in similar fashion to my already prosounded GBC.
So the idea was to replace the capacitors connected to the sound outputs on the CPU with something bigger and fancier .
4.7uF capacitors will do the trick
SOLDER POINTS
Blue - L
Yellow - R
Red - GND
You need to desolder the old capacitors and solder the new ones to the L and R solder points. Then connect the new capacitors and the GND solder point to an audio socket and voila.
It's super easy if you already have a prosound mod.
Oh, and I almost forgot... Here are the sound demos
Raw, recorded in Audacity through Line Input in my PC.
LITTLE TO NO BASS ;(( before
UNLIMITED BASS! after
I hope you'll like it
GBP SOLDER POINTS - NOT TESTED
btw I also made the "noise filtering mod" and its super cool
