LFO = chip included with kit

VACTROL = vactrol included with kit, match plus sign with PCB (compare with pics below)

Q1 = BC337

Q2 = 2n3904

5v = 78L05 regluiator (2 of these)

LED & BYP = LEDs (plus sign on positive leg)

VOL = B100k - volume of wet signal

TONE = B100k DUAL - LPF on wet signal

DEPTH = B25k - LFO depth

WAVE = B10k - introduces random LFO fluctuations (could just label it "random")

RATE = B10k - LFO rate

CHORUS = SPDT ON-ON toggle - adds unity gain dry signal

Schematic

Drilling

>Link to pdf drill template

Notice I use those thinner audio jacks. Please double check spacing if you use different jacks! (I reworked the template slightly after making the one in the pic above)

Wiring

IN = board input

OUT = board output

G = ground from DC jack

+9v = +9v from DC jack

Example wiring for 3PDT footswitch. Also notice two ground connections ("G") for jacks in top left
