From the post

Another great layout from John for a modern booster pedal from TC Electronic.

Info about the original:

Rooted in Tradition, Aimed at Rebellion

Kick your playing into high gear with Spark Booster, a pedal rocking a completely clean boost and heaps of extra features for a world of tone.

A whopping 26 dB of boost Gain knob for added grit and dirt Active EQ and toggle switch for precise tonal shaping

Kickstart Your Tone With a full 26 dB of boost, Spark Booster delivers the juice you need for highlighting solos and nailing that killer lick or riff.

There’s So Much To Gain The Gain knob allows you to add just a hair (or heaps) of dirt to your tone vastly expanding your tonal palette. The active 2-band EQ function as a powerful set of tone shaping tools allowing you to sculpt your tone with unprecedented precision.

Total Tonal Control The active 2-band EQ function as a powerful set of tone shaping tools allowing you to sculpt your tone with unprecedented precision.

The mid-shift toggle allows Spark Booster to focus and amplify all those juicy mid-heavy frequencies that make guitar so great, allowing you to cut through any mix.

Gain Add a hint of grit and compression to your sound to get the same tone and feel cranking and old tube amp beyond "are you insane?!" to induce ear-bleeding levels of guitar heaven.

Active Bass Knob extended lows and added tightness at the turn of a knob.

Level drive amps to peak performance and add body, punch and grit to your gear.

Active Treble Knob Dark and fat or sweet pristine highs with added sparkle and shimmer - the choice is yours.

Maximum You TC drive pedals offer true bypass. It simply means that no matter what your setup or situation, they give you optimal signal integrity so the 'you' in your playing shines through with unparalleled clarity and definition.

Check before you build · 3 values the reader of this layout was not sure of
  • 10K2 at the left of the board (third column of parts, beside 4K3): printed clearly, unusual value
  • Switch on Sw1/Sw2/Sw3: type not printed; three lugs so entered as SPDT (the pedal's three-way toggle would be on/off/on)
  • Several resistors are drawn translucent/standing over other parts (100K beside 4u7, 1M at lower left, 10K lower centre, 4K7 and 100K lower centre-right); counted as separate parts
