i just did this. it was very worth it. there is absolutely NO buzz on batteries with headphones. volume response is great. fantastic. skip the 1/8" jack and do this.
Thanks for this! I just did this mod to my DMG. It sounds great! I actually desoldered the wire from the headphone jack board, and cut the plastic bit that holds the four wires together... I just taped that wire down so i can always revert it by just resoldering the wire back into place. I made sure to run the new audio lines along the shielding as much as possible too. :D Thanks!
Did this mod yesterday, it's 100% worth it! No excess buzzing or humming whatsoever, and I didn't notice too much of a volume decrease. Even if the volume is a bit lower, it's easily solved by soldering to the post-pot connections, which is definitely loud enough on high volumes. I definitely recommend doing this!
+JitterBob it removes the hum/hiss/noise from the internal audio amp. It actually decreases the volume. The purpose is to make it sound better when played through a sound system, usually for chiptunes performances.
Ok, so aperently this decreases the volume, but what about the gbamp3 or a replacement amp? Also, regarding the speaker, is it possible to replace it with one bigger/better?
when I fixed one of my GBs I used one from a laptop, a round, standard speaker, and it really sounds good. you can find matching speakers like these literally in the trash for free.
Hi, after the mod I get an annoying humm. First I thought it's the backlight, but you also have a backlit gameboy, could it be the rechargeable Li battery + charging board which I'm using to power the Gameboy? Maybe I should redo the prosound and check the original out signal. Funny thing that with earphones there is absolutely no humm, the outsignal got so clear (and of course not so loud), maybe my amplifier is causing the humming..., have you any idea?
TheDarkmore so the speaker is humming? or the headphone out is humming but only when you amplify it? it's certainly possible that it's the charging board creating the noise. can you bypass it and run off batteries?
8bitjunkie the sound out was humming, but it was my shi...'not so good' PC amplifier fault :-) Thanks for the guide! Next I will try to install a little 3W stereo ampilier inside the gameboy and add a second speaker so it will have stereo sound on the console itself. I will use the ground and postpot L + postpotR, so I will have volume control. My only problem is that if I will plugin my headphones, the rewired speakers will still have power, which is not good...
8bitjunkie Or the ground pin which you show in this video has already the function to switch off if the headphones are pluged in? Would be so nice, there is plenty of room for a second speaker in the front of the case.
8bitjunkie Sorry for all the spam, but I think I confused myself... when the headphone jack pluges in, it disables the power circuit of the gameboys speaker, right? Ground has nothing to do with this. So my quastion is, where are the pins + / - for the gameboys amplifier? :-)
8bitjunkie Ohh my, this is getting out of control, I mean my ignorance, ground is usally the negativ (sometimes pozitive) so if I will use the ground pin it should work (I hope).
Should be quieter through headphones as you are bypassing the internal amplifier. The point of it is to get better sound quality when connecting the Game Boy to a sound system.

Thanks for the vid my dude! You're Micheal J Fox on that Soldering Iron ;D xo
lol you oughta see me xD i think i'm goin out and being a crackhead in my sleep cuz i shake like a mf
Cool mod. And that is one badass game boy!
The R3ligious hippo Thanks! I need to build another one. Maybe that will be my next video...
Would this also work on a GBC?
So, does this just make the audio better, or does it actually increase the volume?
+JitterBob it removes the hum/hiss/noise from the internal audio amp. It actually decreases the volume. The purpose is to make it sound better when played through a sound system, usually for chiptunes performances.
+8bitjunkie gotcha, so not really beneficial for just casually playing games.
no, not unless you want to hook it up to a little headphone amp to get that 8-bit audiophile experience: amzn.to/1PtnEvb ;)
Kinda sloppy soldering skills but in the end it turned out great. Nice job!
Looks like I could have used some flux - and not drank so much coffee before trying to solder... Thanks!
Honestly just looks like shaking from having to work around a camera while soldering.

Does the speaker still work after doing this mod? I've heard that some pro sound mods permanently disable the speaker.
There's different ways to do the prosound mod. The way I did it in this video does not disable the speaker.
8bitjunkie
Thanks, i will definitely be trying this mod then.
I just did this mod and although there is less hissing it is much quieter than standard. Is this right or have I messed it up?

8bitjunkie Excellent! I thought I had messed something up :-)
Can you control volume?
the way I did it yes. I discuss the two different ways you can do this where you can and can't control the volume afterwards in the video...
Cool
