Very happy with it. Installed in a DMG-01 alongside the clean power voltage regulator. Clean sound, did not bridge contacts for louder circuit either, loud enough as is.
This amp works great. Nice upgrade. If your worried about the soldering don’t be. It’s not too hard but it is very small so I would recommend a magnifying glass and a light. Initially received a faulty amp but Chris from tech was great. Awesome communication. They sent me a new one right away.
The GB/GBP/GBC instructions for this amp ask you to bypass the gameboy's amp, but this product is missing an important feature, that without makes audio actually worse.
A fair number of games actually play music or sounds in stereo. The built in amp will combine the Left and Right audio if you use the speaker. This product does not. instead opting to take only one side. Surely someone who "reverse engineered and analyzed lots of the Game Boy's components." would realize this.
For the GBA the instructions ask you to amplify the speaker output. I guess that works if you just want to make the GBA louder.
this kit is incredible. highly recommend for anyone who really wants to hear their old gameboy console. if you're new to soldering, take your time, and you don't need to max out the heat on your iron. i strongly recommend getting the kynar hookup wire from here as well if you want a really easy time. https://handheldlegend.com/products/kynar-hook-up-wire-5m?_pos=1&_sid=eeb6b6223&_ss=r
if you're an audio nut and the extra loud hissing and humming bothers you, you can get the super teeny tiny dehum kit from here or go get the same mod on an easy ribbon cable from helder gaming tech for a better modding experience https://www.heldergametech.com/?s=game+boy+advance
there are guides to install this amplifier on the gameboy color, advance, and SP, you just gotta look a little bit for the former and the latter.
