After hours of searching for the sound of a guitar hitting the ground, i resolved to just recording a quick piece. This is a small sized guitar hitting the ground a couple times on a carpeted floor (recorded in logic pro).
A. Timmons pickup in the bridge position with mid-long reverb using some pinch harmonics on some tones. The dark airy, possibly almost cavernous, desolation you asked for. . . Be more specific regarding pitches/keys, any tweaks. . . I'll find you.
