“On acoustic string instruments a mic like this is a clear choice, literally! The sound it picks up is as rich and full or as thin and jangly as that of the source.”



“It delivers a superb vocal image that is brimming with uncolored detail and clarity.”



“Considering it can handle high volumes from instruments such as drums, and works equally as well for more subtle items such as strings, it’s sure to become a “go-to” item for any sound engineer.”

Eisley’s music is very vocal-centric, and the amazing accuracy of the SR Series mics really takes the vocals to the next level. More so than any other instrument, everyone knows how a human voice sounds in real life, and when you can actually deliver that sound in a concert, it makes a tremendous difference.

On acoustic string instruments a mic like this is a clear choice, literally! The sound it picks up is as rich and full or as thin and jangly as that of the source. While sources like acoustic guitar are a given with this mic, if I had to pick a favorite it would easily be mandolin. It just grabbed the rhythmic “chuffs” and put them perfectly into the mix on a live bluegrass/folk date.

This year I was hired to mix sound for the Huck Finn Jubilee in Ontario, California, and naturally I took my SR20s with me for all the instruments. They really came in handy when I had to mix the Soggy Bottom Boys (the headliners) following a great, but rather loud, set by Leftover Salmon. The crowd was really cranked up after Leftover Salmon played, so I turned the PA to “stun” for the Soggy Bottom Boys. They sounded like a record! Stuart Duncan, the fiddle player, came off the stage and told Josh Trivett of Moonstruck Management who was in charge of the talent for the festival, ‘I don’t know who your front of house guy is, but that was one of the best mixes I have ever had.’ The SR20’s are like studio quality mics that really behave themselves in extremely tough situations!
