ive been hearing of an Erica synths pro sound mod but it could be folk lore found no info on it...

Uhh yeah that's very confusing.

The video linked on the product's page mentions that this doesn't affect the headphone output at all, but I can't seem to find anything else that confirms this?

RCA mods sound like sh!t , get a hi-fi chip and join the rest of us in 2020 GBA bliss.

anyone know how to stop it crackling tried triacs method and it pops n crackles badly

RCA mod = NOISEY AF GBA

I screwed up the contacts that TRIAC pointed out, but I soldered instead to the ROUT and LOUT just above the jack and am using a 3.5mm jack I cut off a shit pair of earbuds to force stereo. I got a pretty clean signal off of that and I'm happy with the result

I'll update with pictures inside while I put the mod in my afterburner GBA so it's more complete, but there are other pictures in this thread that work just fine to illustrate.

I've tryed to make my GBA promod. It's a bit tricky but technicaly possible. I have solder everything according to TRIAC's recipe but although the audio signal come out of my RCA sockets there is unfortunately loud noise as well. Does anybody have similar experience?

Thanksss for sharing..

Hi guys,
some time ago I found a dude on facebook who gave me some advice on doing a GBA-SoundMod. I tried it out and it works wonders. Here's a few pics of him and of my works:

And here's a sound sample of the Mod:

Compared to the normal sound from the headphone-jack, the sound is way louder, bridges the volume control and alot less noisy.

why would you want RCAs is something i never figured out.  rubberband around the gameboy with the cable going back up and around for strain relief always worked for me to keep it from accidentally getting unplugged

I'll be documenting my process and results, so keep an eye out for that. I'll make an imgur gallery or something

I thought it should be working as a noise cancellation as you should skip componets as potentiometer etc. which generates hum noise or am I wrong? I would like to make this as well in hope of clear audio output.  There were several threads as this one http://chipmusic.org/forums/topic/8529/ … sound-mod/ but there wasn't clear and succesfull conclusion.

thanks! I just dropped 16 bucks shipped on a 3rd GBA to test this out with. I should have results somewhat soon

to be honest, I want to get RCA out on top so I don't have cables coming off the front-side of my table that are easily unplugged if my hand happens to bump them while picking up "deck 1" or "deck 2" to change patterns
