Guitar amplifiers, especially combo amps, are torture chambers to vacuum tube microphonics. Herbie's Guitar Amp UltraSonic Damping Instruments feature extra-soft, extra-beefy isolation pads for extra vibration control. Guitar Amp UltraSonics eliminate tube rattle, tube whistling, and microphonic oscillation that are sometimes too severe for standard UltraSonics to handle.

These are superb damping instruments also for home audio, delivering pinpoint imaging and detail, outstanding transparency and sense of "air," with highly punctual dynamics.
