Last update 23_12_19 improved kernals on bell presets


Based on a 1987 active/discrete clean eq.  Known for its great precision and transparency. Great for problem solving, Mastering, or invisible tone shaping.

Excellent versatility-

  • Fully sweep-able
  • Sharp/narrow to broad eq interpolated
  • choice of interpolated or stepped frequency in low and high bell programs
  • 4 sample rates 96, 88.2, 48,  44,1
  • N4 and N3 JPN skin


  • 15 Hz – 800 Hz low shelf
  • 400 Hz – 26 kHz High Self
  • 15 Hz – 800 Hz, Q of .4 – 4, 15 dB boost/cut Bell
  •  400 Hz – 26 kHz, Q of .4 – 4, 15 dB boost/cut Bell

Surge DEMO is fully functional between 180-400 hz only. Imo this is still great for shaping the low mids and displays sweep and functionality of the library.


How to use instaces in series-

The order of instances is not important on this release.
