Low pitch bass drum. I've recorded some cutoff and resonance on a basic sine wave kick drum patch i created with strobe2 synth. You don't have to provide attribution or anything, but please let me know how you like my sounds here or via twitter @tailorvj.
I put water on the frame drum and hit it several times to get a flat, rattly bass sound. Use my sound so you don't have to abuse your own drums. Recorded on an old ev pl-5.
