Crane Song enters the 500 EQ arena and comes out swinging with this 3 band tube design for API Lunchbox!
INSIGNA is a tube equalizer in a 500 series package, using a dual triode circuit with a 12AX7 tube. It has 3 bands and filters.
Crane Song Insigna Features
- 24 db/oct high pass and low pass filters each with 7 frequencies
- Top and bottom band are shelving each with 8 frequencies

The three bands work by using buffered RC circuits in the negative feedback path around the tube amplifiers. The result is a fat sounding eq rich in second harmonic triode tube color.
