I got hold of a prototype of Kitsch's amp_dmg Game Boy headphone/speaker amplifier replacement board.
It's a direct drop-in replacement with no cutting or drilling required. The stock amp board is removed and the amp_dmg connects to your choice of prosound output (pre or post pot) and takes power from the regulator or other 5V source like a backlight or other mod would. There's connections for the internal speaker as well but I didn't use it.
I've recorded a sound comparison of the stock output and the amp_dmg output using one of my LSDJ tracks here:
There is a noticeable volume increase but the most significant benefit for me is being able to write with headphones using the prosound output without needing an external amp. Also, there's almost zero background hum from buttons presses etc when LSDJ isn't playing.
Kitsch is currently revising the design but when these become available I highly recommend them! In fact, I already wish I'd gotten a few more!
