On the day mini-amps were invented, electric guitar players the world over rejoiced. No longer would they be house-bound when jamming out on their favourite guitar. It is a doubly wondrous day indeed when an electric guitar-inclined maker realizes they can make their own.
[Frank Olson Music] took apart an old pair of headphones and salvaged the speakers — perhaps intending to replicate a vintage sound — and set them aside. Relying on the incisive application of an X-Acto knife, [Olson] made swift work cutting some basswood planks into pieces of the amp before gluing them together — sizing it to be only just bigger than the speakers. A tie was also shown no mercy and used as a dapper grille screen. Both the head and speaker cabinets were sanded and stained for a matching finish.
The speakers are wired to a simple aux jack and connect to an LM386 low-voltage amp circuit which [Olson] assembled and mounted into the header. In spite of our earlier hype, [Olson] seems to be using an external power supply for this mini-amp; but before you count that as a mark against this build, the music you hear him playing in the build video came from the amp. Pair that with this mini-not-quite-a-Tesla-coil, and you’re ready to jam.
