Loved this thing but replaced it with a herb and stones pathways, still has velcro on it.

Pladask Elektrisk description:
MATRISE is an active matrix audiomixer sporting four inputs, four outputs, sixteen level adjustment knobs and individual phase inversion switches for each of the four output channels. This makes for a powerful tool to experiment with signal routing and feedback loops. Among other things the device can be used to run parallel effect loops or amplifiers, add a clean-blend to an effect, or regenerate effects or even the mixer itself.
