EarthWorks SR25

25kHz Instrument Microphone

Precision engineered cardioid condenser designed for drums, guitar amp and other loud instruments

  • 50Hz – 25kHz flat frequency response

  • Cardioid polar pattern

  • Handles up to 145dB SPL without distortion


The Earthworks SR25 is a cardioid instrument microphone designed for miking drums and electric guitars in live performance and studio recording environments.


When looking for that larger than life sound from drums and electric guitar, the SR25 delivers. Sonic timbre and frequency response stay uniform across the entire front of the microphone capsule, helping you capture that perfect tone.

With a lighting fast transient response, the SR25 handles sharp attacks with ease, while still capture all of the subtle nuances and softest dynamics of your playing. With an SPL rating of 145dB, there is no need to worry about distortion or overload, perfect for loud guitar amps and drums.

The SR25 provides a transparent sonic character with an even 50Hz – 25kHz frequency response, faithfully capturing every detail along the way.

Its near-perfect cardioid polar pattern is consistent across all frequencies, simplifying mic placement and ensuring more gain before feedback. With 32dB of off-axis rejection, the SR25 is ideally suited for capturing audio in highly ambient environments and near monitor speakers.

Designed for drums and guitar amps, the SR25 is also an excellent choice for a variety of other instruments such as brass, woodwinds, acoustic guitar and more.
