Game Boy PCB Mount Pro Sound V3

Retro Modding
| /

ASM's 2018 PCB Mount Pro Sound kit features a plated through-hole jack that offers enhanced durability. Its compact design produces a clean, professional look and increases the amount of space you'll have in your Game Boy, so you can add additional mods to your console.

While a typical line out mod screws into the shell, this kit allows for easy disassembly of the Game Boy and increased longevity of the mod. Most Pro Sound assembly kits don't allow you to tighten the nut after installation so, if the nut becomes loose, attempting to tighten it causes the the 3.5 mm jack to spin internally and consequently breaks the connections. The Pro Sound V3 prevents this issue so you can enjoy your mod for years to come.

The PCB Mount Pro Sound V3 uses the original DMG headphone jack, which features a proprietary switch for turning off the speaker and mounting posts to secure it to the case. The additional jack operates as a line-out jack, offering chiptune musicians higher quality audio for live performances and recording.

Not perfect, but do its job

It does not remove noise and hum completely (even paired with power supply mod), just reduces by half, approximately. Anyway, Pro Sound is another step from original Game Boy to the perfect one. If you’ve already applied other mods (screen, power, etc.) – don’t miss this one either.

Easy !

First attemp for me and it worked perfectly. It was easy (It was the first time that I had to sweld something), and it sounds great ! Go ahead !

Easy Install and Good Sound

It's so easy for me as beginner to install Pro Sound. And Good Sound!

black pcb

Honestly I buy this over and over simply for the black pcb that matched the black pcb backlight kits. Ties everything together nicely when put in a clear shell. I've also used this to gift to friends who are into music so they have that raw audio out for any recording they might do. Otherwise I don't play/listen to my game boy games with headphones...

Absolutely love

I build mainly clear systems, and this PCB looks great when paired with a black pcb backlight kit. I just ordered one of their jigs as well to make drilling easier. Easy to install otherwise.
