I suppose this works as advertised, but it is misleading. The amp chip itself doesn’t seem to make audio any cleaner or clearer: the root benefit here it capturing the audio before it is sent to the display board where the speaker normally connects. That probably removes any noise introduced by sharing a audio path with the display connection.
But I can’t hear any difference, other than this amp is obviously much louder (around 4x) than the stock audio capability.
The speaker is a real sore spot. I tested the two and actually kept my DMG stock speaker (both are 8ohm) because it actually sensed better. This can be attributed to a number of factors, specifically, the size. The DMG Gameboy has a much larger speaker in diameter (25% larger) and the magnet is deeper, apx 5 grams heavier, and the speaker fits tight in the case preventing vibration. I suppose the speaker with this kit might be adequate as an upgrade for an SP where the stock speakers are famously buzzy but not for models with larger stock speakers.
Overall worth it for the price but not a necessary upgrade.
Highly recommend this.
I did this for both the Game Boy advance and the Game Boy color. Both times I was impressed by the improvement to sound range and quality. It also lets the volume pot rest in the middle and still be audible, so you don't make your ears bleed by forgetting to drop the volume before plugging headphones in.
Also, I did try the dehum/dehiss guide with the puresilence mod. These are a great way to upgrade this already great mod. These make the audio cleanup done by the cleanamp more effective.
Detail for those you that have clean juice. The original clean juice makes audio hella noisy and the cleanamp will make this more noticeable :( Fortunately, the low power model cleanjuice is much more stable and doesn't introduce this noise. If you have the old clean juice and don't want to buy a new one, I might skip this mod.
CleanAmp Audio Amplifier with Speaker for Game Boy
This is a massive improvement over the stock speaker, you literally can't play full volume for longer than a few minutes. Not a bad thing btw, I always wanted to blast the music when I play pokemon because it gets me pumped and now everyone in my house will know when I'm in a battle lol. I also got the pure silence board so I have no comment on a normal install but I would highly recommend the pure silence board because it's only a couple bucks and 2 more wires. Another quality product from HHL.
the board is super tiny, my soldering skills were just barely good enough. but wow, this guy really made a difference on my DMG. Would highly recommend and i will be using this on a GBA mod later.
The speaker is an definite upgrade over the original but it has some hiss. I combined it with a pure silence chip to get rid of it when the volume is all the way down. All the pads are fairly close so you’ll need a fine tip for your soldering iron to install cleanly.
