DIY Guitar Sustainer

This is my way of giving back to the guitar fam that I sorely miss after becoming an engineer and sacrificing spending time with my guitar.

I've decided to put up a detailed guide on how to build yourself an infinite guitar sustainer that will enable any guitar to hold out a note infinitely long, achieving that violin-like sustain goodness.

The Post-Apocalyptic Tin Can Amplifier

In the case of an apocalyptic nuclear fallout, and you emerge from an underground bomb shelter seeing nothing but a wasteland on top of what was once a thriving human civilization - have no fear! Let this video be your guide to scavenging the parts necessary to build yourself a guitar amplifier so that you can waste your numbered days away shredding guitar and rotting from the side-effects of radiation!

Guitar - Hallelujah (Leonard Cohen, Jeff Buckley)

I haven't done a live recording in a while, so here we go! This one's super short. I was just messing around with the chords to Hallelujah all day while being sick and bed ridden. It's the days like these that make me appreciate the guitar so much - there's not many instruments that you can play while lying down in a nest of blankets and comfort.

Anyway, here's what came out of it, I'll need to come back and add a proper intro to this recording some other time.

Guitar - Sia Mashup (Titanium, Elastic Heart, Chandelier)

I discovered that mashing up songs really doesn't come easy for me. Here's my attempt at arranging a medley of Sia Furler's hit pop songs and the songs I used in it were Wild Ones, Titanium, Elastic Heart, Chandelier, and Big Girls Cry.

Arduino MIDI Drums

With the help of an Arduino, we can turn that Guitar Hero or Rock Band controller into a real MIDI drum kit for recording purposes!

Guitar Cover - Hedley - Pocket Full of Dreams

Hedley's Pocket Full of Dreams from their album, Wild Life. Can't believe their album is two years old and I'm still listening to it! We filmed this one in junk yard using a point-and-shoot camera. Turned out better than I had expected, actually :)
