ALM Busy Circuits S.B.G.

The ALM Busy Circuits S.B.G. is a handy utility module intended to interface guitar FX pedals with Eurorack modular synthesizer systems.

  • Attenuation of outgoing modular audio signal sent to external effects
  • Amplification of returned audio signal to high modular signals (approx. 3db to 34db of gain)
  • Clipping indication on over-amplification of returned signal
  • Manual cross fade between original ‘dry’ source signal and returned ‘wet’ signal
  • Regulation/conditioning of CV modulation signals intended for pedal expression inputs

S.B.G. Basics - Connecting Effects Pedals - ALM006
The ‘S.B.G’ is a compact utility module intended for the interfacing of guitar effect pedals with your eurorack modular system.

It provides both attenuation and amplification of audio signals for level matching together with a crossfade control to conveniently adjust the wet/dry mix of a processed signal. The module also offers regulation of outgoing CV signals for safer use of pedal expression inputs.

Here we look at how to connect up audio and expression CV to a typical effects pedal.
