So I tuned my just 28.6" scale Ibanez GSRM20B Mikro Bass, which is equiped with just 1 single passive bridge J pickup, from the EMG Geezer Butler P/J set, wired directly to the output jack socket, in B standard tuning (as the 4 lower strings of a baritone guitar).
Sound test recorded through my "amp-less" set up, recorded directly into my Zoom H4n handheld recorder, without any edits.
Basic "Clean" tone: 0:00 - 4:32
Tremolo + Flanger: 4:32 - 7:57
Overdrive: 7:57 - 11:50
Basic "Clean" tone: 11:50 - 16:01
