What’s it going to do?
It’ll retain your signal’s top end
despite your lengthy cable run (and
unseen extra length and obstacles
caused by true-bypass in your pedals).
How?
Through some mighty clever jiggery-
pokery concerning input impedance
hich makes the guitar pickups ork
the ay they ere designed to, rather
than ho your home-made Fuzz Face
is trying to make them.
Basically it’ll make your signal as
lovely as it ould be if you plugged
straight into your amp.

Very simple build, and switch-free.
Basically it should sit at the very start
of the signal chain on your pedal
board, and remain on all the time.
here’s no reason to switch it on or
off, or to bypass it.
If you do want to do either of the
above, just wire it up with your own
preferred switch. It won’t do any
harm.
his circuit is standard, Negative
GND. Your power supply should be ip
Negative / Sleeve Positive. hat’s the
same as your standard pedals (Boss
etc), and you can safely daisy-chain
your supply to this pedal.
If you don’t want to have the LED, just
omit CLR and don’t connect the LED
at all.
he kit comes with a socket for the IC,
though the chip is shown soldered
straight to the board on the cover
image.
Long (anode) legs of the electrolytic
caps go into the square pads.
Striped (cathode) leg of D1 goes into
the square pad.
o save some height you can bend C1
over the top of R2,4 as shown on the
cover image.

Wire it up
All the grounds must connect together somehow (both jacks, DC socket, PCB,
LED). hey don’t all have to connect to a single point - they can be daisy
chained. For instance, looking at the diagram above, the ground lug of the IN
jack could connect to the ground lug of the OU jack rather than the DC
socket. It’d still be connected to ground via the OU jack ground connection.
he long (+) leg of the LED should connect to the LED pad on the PCB. he
short (-) leg connects to any ground point.
