The Audible Disease Junk-Fi Sampler JF-2 is a low bit-rate sampler that can record from 30 to 90 seconds of sound and then play it back. The knob changes the pitch of the sample and/or the recording time. You can even play around with the knob while recording a sample and get some ultra-freaky warped samples when you play it back! Record a sample at a short sample rate and crank the knob down for low-pitched crunchy goodness!! The static memory of the sampler will hold the sample even if the power is turned off.
