Testimonials

"JFL Audio equipment is the finest currently made recording gear I've used. My records are always full of JFL sound and the MP F4 Tube Mic Pre is a standout piece- it's in constant use at Sweet Tea and a stunning winner in every mic pre shootout we've had."

-Dennis Herring, producer / Sweet Tea owner

"I have had truly wonderful experiences for years using JFL Audio studio gear, and the MP F4 Tube Pre is one of his best!"

-Terry Manning, engineer, producer & owner, Compass Point Studios

"I had to buy a pair of the MP F6E Channel Strips because they can sound clean without ever feeling stale or plain. I've never been excited about buying really clean sounding gear until I heard this- on the Modest Mouse and The Hives records for example, a little abuse can bring out the musicality of the Channel Strip. And there's no argument about it's flexibility in terms of signal routing and splitting features to different signal paths- a huge plus. Amazing."

-Joe Zook, mixer & engineer
