Sometimes I want to grab the electric guitar just to play a few riffs without having to set up my regular amp.
So I wanted to create a cheap, easy to build and very simple guitar amp: The Pringles Can Amp
Step 1: What You Need:
- A small Pringles can,
- One 5 W mini speaker, (this one comes from an old computer speaker)
- One 6,35 mm female jack
- One TDA2030 amplifier module
- 9V Connector
- 9V battery
Step 2: Glue the Speaker Behind the Lid
Use a hot glue gun.
Step 3: Cut the Lid
Cut the lid with a cutter to free the speaker. Be careful not to cut the speaker membrane!
Step 4: Glue the 9V Connector Outside the Can
Use superglue first and then finish with epoxy resin. Drill a small hole in the cardboard and bring the 9V wires inside the can.
Step 5: Wire the Mini Amp
Plug the 9V batteriy and test with the guitar. I turned the amp potmeter full on and set the volume with my guitar volume knob.
I taped the underside of the TDA2030 to avoid short circuit and installed it inside the can
Step 6: Voila!
I put the 9V battery outside the can for 3 reasons:
- it works as a stand to keep the amp steady
- no on/off switch needed
- easy to replace the battery. I use a rechargeable battery
This amp has no pretention, just grab it and play!
