Q: Can KUKI operate at 18V?
Yes. 9–18V operation increases headroom and dynamic range.
Q: Is it true bypass?
No. It uses buffered bypass.
Q: What does the Clipping switch do?
Selects between three diode clipping configurations:
Hard (silicon)
Natural (LED)
Soft (asymmetrical silicon)
Q: What does the Voice switch do?
Adjusts high-frequency response:
Modern (more highs)
Vintage (more cut)
Classic (balanced)
Q: Can I use it as a standalone preamp?
Yes, especially when connected to a clean power amp or effects return.
