The Ehrlund EAP System is a surprisingly capable contact mic, especially for acoustic instruments where a traditional pickup feels intrusive. It delivers a remarkably natural, detailed sound, making it ideal for solo performers, bowed instruments, or anyone wanting to amplify their acoustic guitar or bass with minimal modification. The preamp offers a good level of control without getting overly complicated.

Frequently Asked Questions

It captures more of the instrument's natural resonance and detail compared to a standard piezo, but lacks the same volume and projection without additional amplification.
While the pad is designed for secure adhesion, repeated removal and reapplication will likely degrade the adhesive, so it's best suited for a dedicated instrument.
It excels with instruments that benefit from a full frequency response like acoustic guitars, upright basses, violins, and cellos – anything where you want to capture the instrument’s natural character rather than a heavily processed sound.
