Installed on my gba and it does what it claims to do.
I had a very noisy gba. Installed this and new capacitors and the buzz and hum are 95% gone.
I got this kit to try to tame the very loud hum and noise the GBA produces for better audio recording. The soldering is a little tricky with the tiny capacitors, but overall not so bad. The results are great! I can amp the GBA audio up to good levels now.
The kit doesn't remove ALL of the noise. For me, all that is left is a very soft hum that isn't audible unless amped up to very high levels. I'd say the noise floor is cleaner than a pro sound modded DMG.
Got rid of the annoying high hiss. A must have for your sanity
Easy to install and noticeably quieted the noise from the system.
The audio has a ton of background hum on the GBA this was very easy to soder and take a way MOST of the hum. For $4 it is a must.
