Like a Gumball-kid in a candy store..
Pink and Blue case swap looks pretty sweet on the Gameboy Color. Sounds cool too with the Pro-Sound mod.
A bit more focused in the low-mids compared to a DMG-01, with a tighter sound overall i think. Not as much bass, but the noise channel is a bit crisper, without the bassy pops that you get with abrupt envelopes on the DMG.
The sound of this thing brings back 80's+90's Nintendo memories, where as the DMG sounds more like some ferocious wildebeest that could never truly be tamed...
..oh yeah, and its got a sharp colour screen too.
