Here's my take on the famous Little Gem mini guitar amp.
All details on the electronics can be found at runoffgroove.com.

The case came from Jameco p/n 11886.
The speaker bezel is the rim of a tin can that was epoxied to the case.
The disk in the rear serves as a cord reel.

Hi. I've been studying the schematics and the pictures you posted and since I'm a beginner I'm frustrated because I don't understand a few things.
For instance, where do I put the speakers, dc-in, dc-out, the on-off switch, the 5K vol pot? That's not represented in the schematics, is it?
I apreciate the help you can give.

Hi NunoMorna -
Sorry, the dc-in and dc-out are special to this build and not necessary.
Your other questions can be found at this great Instructable.

someone gave me a mini guitar amp that you can buy online for $20. they said it was broken but i took it apart and found that it was just a disconnected wire that runs to the male input/output jack. it runs on a 9 volt and it doesn't require a cable to connect to a guitar. so i stripped it down and went to LOWS and bought a slab of pine wood for $3. i cut the wood into 4"x3" pieces and made a box, added all the components and designed it to look like a Marshall half stack. so now i have a mini Marshall half stack for $3! thanks for the inspiration - myakka

What speaker are you using?
Reply 12 years ago on Introduction
Sorry, the speaker I had in my junk box and I forgot where I got it. There's no name or number on it either. Any 4 or 8 ohm speaker should work.

this is very cool how much is the price to make this?
sorry for my bad enlish

Thanks! Sorry but I didn't keep track of the cost of this build. Most parts were spares or left overs. The most expensive part was the box itself. About $9.00 US at Jameco. : )
