4 port low noise active mixer that can be setup as either 3 in 1 out, 2 in 2 out, 1 in 3 out (buffered). the top channel channel is always an in, bottom always an out. middle two are configurable with a toggle switch. Each channel has its own gain control. Jacks are face mounted to save space, dc jack is on the top. Case is the '125B' size.
Applications? mix several parallel effects together (split with y cables then blend back together), feedback looping (2 in 2 out could achieve this), splitting signal to low input impedance effects (like some fuzzes in parallel) etc. Personally i built one for myself to mix 3 looping pedals together.
Runs on 9v dc. No battery space inside. Text is engraved and pedal is powder coated. Not available right now but maybe soon.
