Heck took apart the kick pedal that came with GH4's drum set and used the piezoelectric switch in it, McGuyvered it into a little chamber with a diaphragm and added a tube that uses air to hit the switch. Voila, instant breath-controlled pedal!

Want to help a friend in need? Heck's posted the way to do this mod on his [website. [Hackaday]

Drums:

Drum Kit Shirt: Sure, you could by a real drum kit—but that can be expensive. This drum kit shirt plays seven drum sounds when you tap different areas and it will only set you back $30. [Think Geek via Link]

Drum Table: Yup...it's a table with drums built-in. The way I see it, this would be a great way to score with the ladies when everyone is drinking at a party. I mean look at this dude, he seems well on his way to a foursome. Prices range from $800 to $2,900. [Musical Furnishings via Link]

DrumPants: By dismantling a MIDI keyboard and hooking it up to his pants with a couple of piezo transducers, Tyler Freeman was able to turn his legs into playable drums. If you throw the shirt on top of this, you would basically turn your entire body into a giant kit. [Link]

Guitars:

Angel Sword Guitar: Slay your fans with rock and slay your enemies with steel. Too bad this nerd axe is a one of a kind item. [Link]

Gibson's Robotic Guitar: If you are too lazy to manually tune your guitar, this Gibson will do it for you at the push of a button. Servos tune the guitar to one of seven presets with A440 as a default and the remaining six based on hit songs. Unfortunately, this limited edition instrument will set you back well over $2000 if you manage to find one. [Gibson via Link]

Moog Paul Vo Edition: Moog, a company known for their synthesizers, have branched out to the world of guitars with the Paul Vo Edition. What makes it worth $6500 you ask? Well, it sure as hell isn't looks. However, it does claim to have "infinite sustain." Sure, you can already achieve similar effects with pedals, but the Moog product site claims that it is "like no other sustainer; infinite sustain on every string, at every fret position and at any volume. You may have heard sustain before but not with this power (we call it "Vo Power") and clarity." [Moog via Link]

Synthesizers:

Beamz: The Beamz system uses a series of six lasers that play sounds from instruments like the guitar, violin and even the cowbell when the beam is broken with your hand. If it feels like a Sharper Image gadget to you, good call. Beamz was on sale there before the company went belly up. Don't let that deter you though. You can still get your hands on one from the Beamz website for $400. Oh, and this video is the most hysterically uncomfortable thing I have watched in a long time. [Beamz via Link]

Korg DS-10: Unlike Guitar Hero, you can actually use this game to make music. Basically, Korg took their famous MS-10 synthesizer and squeezed it onto a DS. It features a four-part drum machine, six-track (analog synth x 2, drum machine x 4) /16-step sequencer, delay, chorus and flanger sound effects and the ability to exchange sounds and songs and play multiple units wirelessly. Currently available in Japan for 4,800 yen ($48). [Korg DS-10 via Link]

Piano:

Mini Grand Piano: Have you priced grand pianos lately? Yeah, we are talking tens of thousands of dollars. The good news is that this version from Segatoys will only set you back $570. The bad news is that each one of the playable keys is only 4mm wide. It may be mini, but you can still play like mozart with a stylus. [Audiocubes]

"Alternative" Instruments:

Light Up Tambourine: Okay, maybe cool instruments aren't your thing. However, that doesn't mean you can't rock out. Hey, Davy Jones got lots of chicks playing one of these back in the day. Available for $15. [LB Toys]

Air Guitar (Bonus): So you are good at Guitar Hero but you lack actual musical ability. No worries—you always have air guitar. And if you are wondering how you can get groupies doing something so lame, check out the video of air guitar champion Ochi Dainoji Yosuke doing his thing. So the lesson here is that it's not what you play but where you play it. I'll bet groupies are into anyone performing on a stage. Available for around $4. [stuff4me]
