R28
LOCATE R28 ON THE PCB
R28 is the resistor just above the output jack.
Desolder and lift the leg of R28 that is closest to
the edge of the board (pictured). If you are having
trouble sufficiently heating the solder, flip the board
over and desolder the back of the pad. After the
solder has been removed from the pad, carefully
lift the resistor leg from the pad. To do this you
might need to heat the leg and the pad with your
soldering iron. Be careful not to break the other leg
of the resistor as you are lifting the left one.
In the next steps you will prepare the switch to
attach to the R28 resistor. The switch will take the
resistor in or out of the circuit, letting you change
between the stock “block” sound and the vintage
“script” sound.
