Can I play guitar through SuperKar+?

SuperKar+ is an effect module designed to receive synth level input signals.  A standard guitar’s output is typically about 18dB too quiet to work well with SuperKar+ and the input impedance does not match well with a guitar’s high output impedance.

Plugging a guitar into a boost pedal that can provide at least 18dB of clean, high-headroom gain will work to raise the input level and provide better impedance matching for SuperKar+’s inputs.

We also have our own module available called AA.1 to interface guitar level signals with SuperKar+ and other Eurorack devices.  It has at +18dB amplifier to boost your signal for Eurorack and an -18dB attenuator to lower your Eurorack signal down to instrument level for guitar setups.
