Flyleaf Envelope Follower

From the vendor

The Flyleaf is based on the vintage EHX Zipper Envelope Follower that debuted

in 1977. It has been adapted to use true bypass switching and includes an in-

ternal trimpot for adjusting the effect for bypass unity via an onboard clean

boost. This boost is based on the LPB-1.

Although the original circuit used 2N4302 jfets, we’ve found 2N5485 to be an

ideal substitute, although others might work ok too.

NOW AVAILABLE with (or without) 3x (roughly) matched MMBF5485 soldered to the pcb, which would be very convenient for those who’d rather not shop for the JFETs separately.
