Loki Mini is a single-gain-stage active EQ with non-constant-Q passive filtering. In more English-y terms, that means that each band varies from broad to narrower as its gain is increased-small turns of the knobs result in broad, shallow changes, and bigger turns result in more narrow-band changes.
Instead of a stack of noisy op-amps attached to open-frame, dust-collecting sliders, Loki uses a single, discrete, current-feedback gain stage, coupled to passive LC filters for 3 bands, plus a gyrator for the bass. Sealed Alps potentiometers with rational adjustment ranges allow for fine control. Coupled with a 100% passive bypass setting, Loki offers the transparency and flexibility you need.
