Good Friend is one of those gems you can find if you follow your Discover Weekly list on Spotify religiously. I knew Emily King from another song called Distance that was transcribed and covered by Pedro Zappa. Despite that, I never looked into her album called The Switch until Spotify listed Good Friend.
There are a few interesting bits about the bassline, the electric synth sound which was played by Mike Lavalle using an original Novation Bass Station, the slightly awkward and sustaining chopped-off rhythm and those nice, tasty fills. To recreate that sound I resorted to a Markbass MB Octaver which is a discontinued, faithful copy of the venerable BOSS OC-2. But I am GASing for a Novation Bass Station II now for a while already.
