Love how quick it is to install. This works great on AGS-001 and AGS-101. No humming sound on the AGS-001 compared to the previous CleanAmp.

Easy install good quality.
Excellent seller communication.

I was expecting this to be loud but you never really know until you install it, just how loud it really is. It can be easily heard from another room and it really is obnoxiously loud. I cannot play full volume it’s just too much to have the game screaming at me lol. The install is very easy it’s just five solder points it takes like a minute. One more thing is you will need a dehum kit to get rid of background noise amplified by this mod. Overall, if you want a truly excessively loud gba sp and want your ears to go deaf by all means get this mod.

I was blown away by the audio difference with this amp. My SP is now obnoxiously loud at full volume. Great mod!

"That's too loud daddy!" was the first thing my daughter said when I turned my GBA SP on at full volume after installing the CleanAmp Pro. I've installed three of these now and the only downside is connecting the ground pin to that tiny resistor. On one of my installs, I accidentally removed the R17 (3k Ohm) resistor in the process of trying to pre-tin the ground pin. The other two installs I did were fine, I just botched that one. I found replacement resistors so hopefully I can fix it. If you're concerned about messing up the resistor like I did, just use an enameled wire and run the GND connection on the flex PCB over to pin 5 on the power plug. Pin 5 on the power connector is the audio ground. Use flux, don't put too much solder on and you'll be fine. The sound quality is amazing. Slight hiss when no sound is actually playing, but I have to hold it close to my ear to really hear it. When the volume is off, the unit is 100% silent.
