A boost "pedal", an ornament, a fun project kit, a conversation piece

Rockin' Around the Christmas Tree

Playable Guitar Pedal Ornament

So what exactly is this?

Playable guitar pedal ornament
And how does it work?

Flip the switch to make the lights blink. Plug in your guitar to engage the Nine Volt Nirvana Tape Measure audio circuit (schematic).

How does it sound?

It gives you a pretty decent boost, around 25dB, and a bit of gritty overdrive. When cranked it has a bit of a lo-fi vibe to it.

How do I get one?

This is available pre-built, or as a DIY kit that you solder together. If you can't or don't want to order a PCB you can get all the files needed to make your own on the GitHub project page.

Instructions / How To

Using the Pedal

There's really only one non-obvious thing to be aware of: when your guitar cable is plugged in, the pedal is using power. Unplug it when you're not playing. This has two circuits: the lights controlled by the switch, and the audio controlled by the input cable.

NOTE: If you experience a ticking noise while playing, turn off the pedal's blinking lights. Or embrace it and shrug it off because your guitar is plugged into a freaking Christmas Tree, hanging on a bigger Christmas Tree.
