Assembly Instructions
The JHS808 is one of the great stompboxes from JHS, mak-
ers of high-end effects pedals. Whenever JHS adds a new
pedal to their line, they retire an existing design. This means
great JHS pedals like the JHS808 have become rare and
sought-after. You can't buy one, but you can build yourself
one—and it's fun!
Back in the late 1970s, Ibanez introduced the TS-808 Tube
Screamer, possibly the most famous overdrive pedal ever
made. Favored by many discriminating guitarists, including
Stevie Ray Vaughan, Eric Johnson, and Joe Bonamassa. Often
copied or modded, the Tube Screamer circuit has become
the platform for most modern overdrive pedals.
Using an original vintage TS-808 as a starting point, Josh
Scott modded the circuit to include a three-way gain toggle
that switches between the stock circuit, boost, and crunch
for added flexibility. The result is this JHS808.
