Ibanez AD-9
Keeley Mod
Mod Only


IMPORTANT: You are paying for the modification which will require you to ship your pedal to us.

The Ibanez AD-9 is a great starter analog delay pedal. It doesn't feature super long delay times (typically 310-330ms max with a minimum of about 15ms), but it does have great frequency response and fairly clean repeats. This pedal is ideal for that "slapback" delay sound. With our modifications we change/upgrade 14 capacitors in the signal path to improve the overall frequency response, including bass response, and to lower the overall amount of noise. We also add true by-pass switching to ensure that there is no tone loss when the effect is off. Lastly we modify the pedal so that the original switch can be used as a swell control. Whenever you step on this switch it maxes out the repeats sending the pedal into instant feedback.

What you get with the Ibanez AD-9 Mod!

  1. Better bass response along with high frequency transparency 
  2. Lower overall noise floor
  3. Blue LED 
  4. True By-pass switching
  5. Infinite repeat switch
