Not just a mixer. Also a stereo distortion/saturator with a pre-routed feedback channel

Bestie is a 5-channel stereo mixer with up to 20 dB boost, mute switch per channel, and flexible connectivity. However, Bestie is not just a mixer but also a stereo distortion/saturator with a pre-routed feedback channel that can create juicy, crunchy sounds.

Beauty and the Beast in a full metal jacket

Mixing with Bestie can be pure vanilla if you keep all the levels left of the 12 o'clock position. But once you start boosting, Bestie can quickly turn into a Beast. As soon as you start to overload the mixer, the sounds can start to fight for dominance.

The dedicated headphone output offers a loudness control with a smooth mixdown overdrive character and a pre/post mute switch for pre-listening to all your channels before unmuting them to the speakers.

Channels 1 and 5 have a flexible connectivity scheme accommodating 2x mono cable for left and right channels or 1x cable mono to split to both channels or a classic stereo jack.

No input? No input!

A big part of the sonic aesthetics of Bastl Instruments and Casper Electronics is influenced by the so-called no-input-mixing technique. This is the technique of routing the output back to the input on mixing consoles and using gain and EQ to create different tones and noises without plugging any signals into the mixer.

However, fascinating outcomes arise when these feedback signals are interrupted by elements such as drums. They interact with the feedback tones and compete for dominance. Bestie is well suited for such experiments and directly encourages you to overload its circuitry and make the signals go ape.

Zero strings attached

USB-C and AA battery power options make Bestie perfect for portable setups without compromising sound quality.
