I wouldn't have wasted my time if I had known it only amplifies the right audio channel. I know the gameboy only has one speaker, but the audio typically outputs both channels to that speaker. While this mod does make the volume louder, its only for the right channel. You'll miss so many of the instruments and sound effects in games that use both channels. It was very noticable in pokemon crystal, sounded like a different song entirely. This also makes LSDJ, nanoloop, impossible to compose chiptune music with. Very frustrating that this isn't at least stated anywhere. I would have bought a DIFFERENT audio amp that supports stereo to mono mixing.
Very good amp and well made. If your looking for loud and clear sound this is a good product. The crew at HHL was ever helpful in taking the time to walk me through the install and what to check if no sound. Overall I like it, I do wish it was a tad bit bigger. Can't tell you how many times I went crossed eyed.
Gives me the sound I needed specially when watching the gba videos
The solder pad and traces came off the board on the first wire I tried to solder.
I have installed this into DMG and Color and they have worked great. The only issue I have had is installing it into the SP. Even with the case trimmed per the instructions, the D-pad and A/B buttons are shallow. If there is a solution for that then I would make this 5 stars.
Despite the system noise, I really do like that I can crank the sound up to 11. Instructions were clear and easy to follow.
