Ashdown ABM500 EVO III treble knob question

Discussion in 'Amps and Cabs [BG]' started by jcburn, Jan 22, 2017.

  1. This may be a dumb question, but after many years of playing I'm only recently starting to get my head around different types of EQ.
    So the treble knob for this amp is +/- 15db @ 7khz "shelving" - does this mean it acts a little like a low pass filter at and above 7khz with the knob turned down?
  2. Yes.
  3. Haha, nice simple answer! Thank you!
