Welcome to The Jam Jar  

The home of the glassy tone 


Guitarists are always banging on about glassy tones but The JAM Jar delivers them quite literally - cramming a 2.5" speaker into an actual glass jar and turning it into a working guitar amp.

We have two Amps: The JAM Jar and The Blueberry.

The 'JAM' Jar is the original  and is a 0.25 watt high gain amp. 

The Blueberry is a 1.25 watt, lower gain amp with higher volume.
