original nintendo gameboy dmg 001 "pro sound" mod

i have been playing with nintendo gameboys as a sound generation device for my music fun, i recently tore apart a couple of old gameboys, the original big grey one, and a black one, model dmg001

this simple mod increases the volume of the gameboy, it makes the lows a bit larger sounding, it also decreases the amount of line noise that one would usually get with an original gameboy

you can see here, there are only 2 wires, 4 solder points, very simple, the solder points are very close near the original gameboy headphone jack, i almost destroyed the first gameboy i tried it with! the huge gob of solder my shaky hands placed was so close to the other wire's large gob o' solder, i'm very fortunate i didn't destroy it, haha =)

i have seen many other mods online, many will use a seperate output jack, that's cool, but i personally didn't want the outside altered, and i'm a bit lazy, plus imho it looks way cleaner...some other mods will cause the built in speaker to no longer function if there is nothing plugged into the headphone jack, this mod lets the built in speaker function normally ;)

disclaimer: i take no responsibility if you screw up your gameboy by trying this
