In many forum posts I’ve read there is talk about the extremely long delay times you can achieve with the Memory Boy when you plug in the expression pedal. Although this is true, it doesn’t have to be.
Here’s how to set the Memory Boy’s maximum delay time when using an expression pedal to control the delay time:
1. Connect an expression pedal to the Memory Boy’s Exp. Pedal input jack.
2. Set the exp. pedal to the toe down position.
3. Play a note on your instrument and turn the DELAY knob to the setting that gives you the maximum delay time that you want. Setting it to about 9 o’clock will be approximately 500 mS.
4. (OPTIONAL) Depending on the type of expression pedal you might be able to adjust the minimum delay time when the pedal is in the heel position. The Boss EV-5 and M-Audio pedals have a grey knob on the side, turn this knob to increase the delay time when the pedal is in the toe up position. The further you turn the grey knob away from zero, the longer the minimum delay time will be.
Also please note the polarity of the expression pedal has the wiper connected to the TIP on the plug. This is Roland style polarity. Most expression pedals use this polarity or give you a choice. Yamaha expression pedals will not work with the Memory Boy.October 15, 2018 at 1:06 pm #124394frailMember
I got a Deluxe Memory Boy and wanted to experiment with my expression pedal options.Quote:Also please note the polarity of the expression pedal has the wiper connected to the TIP on the plug.

A friend loaned a Yamaha expression pedal and it KIND of works but I can’t get the full knob range.
Meaning, I want to use my EXP ped to go from 0 to 10 in the feedback knob. I set the knob in 10 but the whole range I get with my EXP pedal is 7 to 10. If I set the pedal at 5 i will get 2-5 (approximately). That happens with any parameter I assign to the pedal
If I buy another brand EXP pedal will I be able to get the whole range of the knobs? Is there any possibility there is a defect in my EHX Deluxe Memory Boy?October 15, 2018 at 1:23 pm #124395Flick (EHX Staff)Moderator
Yamaha expression pedals have the wrong polarity for the Deluxe Memory Boy and do not work properly with the DXMB. I don’t believe there is a defect with your Deluxe Memory Boy, it is just incompatible with the Yamaha expression pedal.
Most other brand expression pedals should work fine with the Deluxe Memory Boy. Make sure the TIP of the expression pedal’s TRS connector is connected to the wiper of the expression potentiometer.
Some suggested expression pedals include:
M-Audio EX-P (set to M-Audio)
Moog EP-2 and EP-3
