Game Boy Advance Flex Amp - Robot_Retro Tools Tap the left touch padThis flex amp for the Game Boy Advance enhances the audio and also addresses issues with other flex amps that are too loud and don't have adjustability. WHAT'S NEW WITH v2: The speaker now includes a full size insulative sticker to place on the back, preventing shorts against the metal speaker casing (see photo). By default, the amplifier mutes audio below ~25% of the volume wheels travel. This can be disabled by bridging solder point S1 (see photo).
