katsumbhong did a great job documenting everything

the mod is an evolved prosound

Does anybody have a picture of the gameboy color PCB with the 4.7uF cap installed?

If the GBC is prosound modded does this also boost the bass output there as well?

Ah alright, thank you!

Hey, bigger cap equals more bass

I tried borh smaller and bigger caps and decided that 4.7uf makes the biggest difference without the sound being muddy

I want to boost the bass further, should I use higher or lower value caps than 4.7uF?

scannerboy, did you ever try this with 10uF?

Unfortunetly I don't have access to a pro sounded DMG. If you want you can record it yourself. Here's THE LINK to the lsdsng

PS: Sry for the late reply.

This is great- can you post a third comparison of a DMG playing the same song sample? If the bass is comparable, I may need to transition to the GBC!

I've got only these two crappy pictures made with my phone - 1 and 2

I don't think it's a ideal solution beacuse I'm pretty sure that there is a more comfortable GND point. Also it would be a good idea to incorporate the volume pot for volume control and the gameboy proprietary audio socket for a cleaner look.

scanner boy can you post a picture post-mod as well?

nice!

dang, nice! pretty great difference.

edit: that little sample sounds nice too.

works now?

dl link for unlimited bass no worky

SirPrize: I'm pretty sure these are the two but I can't test it so I'm not 100% sure ;/

Red - L
Blue - R

ant1: if you desolder the capacitors you won't get any sound from the speaker

i don't think this BASS MOD affects the sound you get from the speaker

the lack of bass there is something else not caused by electronics
