Aspen Instruments Black Diamond Probe

Black Diamond Probe pairs with Black Diamond Distortion. While Black Diamond Distortion lets you build and edit transfer curves—Probe extracts those curves from real hardware or plugins.

Run audio through any nonlinear device—a tube preamp, tape machine, or overdrive pedal—and Probe will extract the transfer function that defines its distortion character. Export the curve as a .tfunc file, then load it into Black Diamond Distortion to reuse it, refine it, or push it further.

Use Cases

Learn what your gear is actually doing: See exactly how different tubes, transistors, or op-amps color your signal. The principle is the same whether you are probing real hardware or software models.
Build a personal curve library: Export .tfunc captures from your favorite gain stages, then load them into Black Diamond Distortion to reuse, tweak, and push further.
