8-Channel Dual-Bus Eurorack Mixer

Tenderfoot Electronics – KOMBIN-8
8-Channel Dual-Bus Eurorack Mixer

KOMBIN-8 is a compact, chainable 8-channel mono audio mixer designed for Eurorack. With two fully independent send/return buses, it’s equally at home in traditional studio-style setups or experimental signal chains. Each channel offers dedicated send controls for both buses, plus rear-panel switches to select pre- or post-fader operation for ultimate routing flexibility.

Its clean, passive-fader topology delivers low noise and a direct signal path, while the chainable design means you can link multiple units into larger mixing systems without adding complexity. Whether you’re building a compact performance skiff or a sprawling multi-case setup, KOMBIN-8 is ready to be the heart of your modular mix.
