- No additional accessories included
The HRK US Pentode is a Colour module designed for use in modular synthesizer systems. Colour modules are passive or semi-passive format inserts that shape the tonal character of audio passing through them, typically introducing harmonic coloration, saturation, or filtering characteristics drawn from classic circuit topologies — in this case, a pentode valve-inspired design. The US Pentode format places this kind of analog harmonic processing directly into a modular signal chain, making it a useful tool for adding warmth, grit, or vintage tube-style texture to synthesizer voices or other audio sources.
A great opportunity to own a HRK US Pentode at this price point.
