Jam6

JaM6 is a handmade portable stereo mixer powered by a 9v battery. It has 6 unbalanced stereo channels with mini jack inputs and output. It’s the best mate of pocket instruments and musicians “on the go”. You can use it on your own or share it with your friends and make a tasteful juicy jam! Jam6 Strawberry it’s armed with a TL072/NE5532 OpAmp that gives a Lo-fi taste to your mix.

We designed Jam6 in 2019. On June 2020 we accomplished some updates to the original design such a more stable battery holder and better quality internal isolation. We also added a small plastic leaf to cover the toggle switch.

Design

Jam6 is made out of a glass jar and 3D printed PLA elements, realised with FDM (fused deposition modeling) process. The right mix of air and PLA amount during the printing process makes the plastic parts soft and flexible without loosing the original shape and grip. Jam6 is only 10cm wide and 6cm tall.
