This amplifier is a game changer! Easy to install and works as intended. Shipping was fast and I appreciate the awesome stickers. Thank you!

If you're looking for an easy solution to get more amp out of your GBC speaker, this delivers. The YouTube video installation out there made by HHL is concise and easy to follow. Love my new volume level. Thanks man!

The item works great. The only issue I had was it wasn't as photographed. Rather than a curved corner on the bottom left it came to a 90° point. This meant that it didn't fit flush in the case. Being a flex cable, I was able to contort it to fitting.

I purchased two of these since the GBA SP ribbon amp works so well I was so happy to see this come out. The Funnyplaying chip can add extra space as well as have the possibility of cutting wires when sealing if not placed properly in non clear shells.

I've installed two of these and removed them just to replace them with the funnyplaying sound mod chip. One GBC with clean power mod and one without, same result on both. Its the same volume with the mod, no boost what so ever.

I'm so disappointed in these and feel this is a waste of time and money, if there is a trick to boosting the sound in the "pending install instructions" I'd be very interested. If I could give this a negative star I would currently.

Install of this Amp was exceptionally quick and simple. Like the CleanAmp, it seems to be wired sorotating the volume wheel down increases the volume and rotating it up decreases the volume. Compared to the cleanamp, the sound does not appear to be amplified at all, but it also doesn't make the hissing noise either.

This piece was designed very well, it lines up perfectly and was easy for a novice/intermediate solder-er to accommodate. Paired with a new speaker from HHL, the GBC's sound is noticeably louder than stock. I'd suggest HHL remove the image showing the highlighted capacitor; if it werent for the 'question' being asked on the product page I would have been a little lost to that image's purpose.
