Details
Controls: High Cut, High Boost, Low Boost, Low Cut controls, each with a frequency-select switch; bypass switch
I/O: Front-panel microphone/instrument input; transformers in both input and output stages; fits standard 500-series rack/lunchbox
Notes: FLAG 500-vs-rack: 500-series module version of the passive LC EQ circuit found in the VLC, itself originally from the D.W. Fearn VT-5 (flagged D.W. Fearn heritage — two generations removed: VT-5 -> VLC -> DLC). Shares filter capacitors and hand-wound inductor with VLC per Vintage King, though audio path differs slightly (hybrid tube-input/solid-state-output vs VLC's fully tube path — flagged). 12dB bell boosts / 12dB shelving cuts across stated corner-frequency pairs per third-party spec summary. 7-year warranty (90 days tubes). Price $1,199 consistent across Sweetwater/Vintage King/Perfect Circuit.
