Gearank Recommendation

The Blue Spark SL appeared on our recommended list for Large Diaphragm Condenser Mics Under $200 from April 2021 until February 2022 when it was removed due to being unavailable.


The Blue Spark SL is the successor to the original Blue Spark; prioritizing detail and transparency,

Blue spec'ed the Spark SL with a custom JFET design to ensure the capsule's backplate is evenly charged for best pickup.

Class-A circuitry ensures transparency and low noise.

Rounding out the main specifications are a 100hz filter and a -20dB pad for added versatility.

Want a crisp sounding condenser microphone for your voice or acoustic guitar? The Spark SL delivers in more ways than one with its excellent clarity and detail.
