What does it do? Really??
It boosts your treble. And perms your hair.

Wiring shown overleaf will disconnect the battery when you
remove the jack plug from the input, and also when a DC plug
is inserted.
nap the little metal tag off the pot to mount it flush
in the box.
You MU T use some kind of heat sink on the legs
of the transistors when soldering. They aren’t
keen on heat. Any more than 3-4 seconds of iron
and they’re toast.
Recommended assembly order:
Resistors, Caps, Transistors, Wires, Pots
I’ve incorporated the Current Limiting Resistor for the LED into
the board for your pleasure.
NOTE: + leg of C4 goe here - apologie , I didn’t mark it.

Test the boar !
Once you’ve finished the circuit it makes sense to test is before
starting on the switch and LED wiring. It’ll cut down
troubleshooting time in the long run. If the circuit works at this
stage, but it doesn’t once you wire up the switch - guess what?
You’ve probably made a mistake with the switch.
older some nice, long lengths of wire to the board connections for
9V, GND, IN and OUT. Connect IN and OUT to the jacks as shown.
Connect all the GNDs together (twist them up and add a small
amount of solder to tack it). Connect the battery + lead to the 9V
wire, same method. Plug in. Go!
If it works, crack on and do your switch wiring. If not... aw man. At
least you know the problem is with the circuit. Find out why, get it
working, THEN worry about the switch etc.

Wire it up
The Board GND connections don’t all have to directly attach to the
board. You can run a couple of wires from the DC connector, one to the
board, another to the IN jack, then daisy chain that over to the OUT jack.
It doesn’t matter how they all connect, as long as they do.
This circuit is standard, Negative GND. Your power supply should be Tip
Negative / leeve Positive. That’s the same as your standard pedals
(Boss etc), and you can safely daisy-chain your supply to this pedal.
Now... GO GET TREBLEY!
