Rack Attack!
Being nostalgic at heart and also super into electronic music, it's no surprise that I have a 12u rack full of synths from the 90s and early 00s. Before the days where you could load a boatload of software plugins into your DAWs, you would use mainly outboard synths and effects for your music creation and use your PC for MIDI. The best way to get an old sound is to use old stuff! :D
