the first device i evar built was an amp (age 14). i played through it for about 10 minutes, my guitar sent 220 volts through my hands(i completed the circuit) then the amp burst into flames(plywood cab.) wow, haven't thought of that in years, that's some funnay shite, wish it happened to someone else.

Owch, well when I build one of these it'll only use 9v - what happened to ur guitar?

FRIED

I actually bought a little pocket amp a few years ago, worked awesome till I ran it thru the wash :)

I think I'll give this a go (they are great for quick re-tuning backstage).

cool, lot's o' musicians, maybe if i grow some balls, i'll put a couple of mp3's up..i'm scared though, i wuv you guys..but brutal bastards, all of ya

I'm not brutal. I'm gentle as a bunny. A bunny with nasty, big, pointy teeth, the most foul, cruel, and bad-tempered rodent you ever set eyes on.

Beware the bunny of Caerbannog. Grrr.

hey Evil...i looked at the schem., i gots all the shit. i'm gonna build one tonight, i'll let ya know. i'll even bet i can add reverb with a pen spring

Notice that nowhere in the article does it say 'Guitar amp'...

but of course it could be used as one, to power headphones.

Yeah - true, it might need a mod to deal with the mono input, I guess a single amp op-amp driving left and right on the headphones - still - it'l do the job and it looks cool, and its easy to build - I still think I did the world a great service bringing this to worlds attention - you may bow

Ghostrider: you gotta let us know how it turns out, if the mods are simple to make. I havn't got the parts just yet.

Related to japroach's 'guitar amp' observation --

Any one here savvy enough to describe what measures would need to be implemented to make this device suitable for bass guitar amplification?

Same changes as a guitar amp, you ain't gonna get super clarity out a thing so cheap to build anyway

All you need to do is have a mono input socket - if ur opamp chip has two amp circuits in it (Left and Right) run the signal to both'o'them. Or use a single channel opamp and drive left & right headphone speakers from the output - wont get as much level as a two channel part tho'

i fear a mini pre-amp would be needed for bass, or a capaciter(sp) to 'dampen' signal

so spend fiddy dollah, and get a 25 watt Peavey at teh pawn shop:)

ok.

My genius is NOT a myth, because like a TRUE GENIUS, I would like my personal tiny bass guitar amp housed inside a cigarette tin.

Kuel! Mines goin'in' beer can - ha now ur all fux0r'd
