MM Delay Docs


Thank you for buying the Memphis Mini Delay pedal!  We are very proud of its value and performance.   The pedal will give you a very nice slap-back effect to fatten up your sound for that old-school Chicago tone.  Depending upon the settings you choose the pedal can also produce some very cool echo effects.  It's a warm sounding digital delay pedal built to our specs to perform like an analog delay.  The delay tails have a nice organic decay.  It has true bypass, a metal housing, and is very well built. 
This is a great sounding delay for a player who wants to get his tone a little wet.  I think less is more with delays (as with most effects).  In this video the three controls (Level, Delay, and Repeat) are all set at the 9 o'clock position, giving the tone a nice fat slap-back sound.  The pedal has the capacity to get more of a Space Echo sound if that is what you're into.  The delay intervals can be dialed in from 25ms to 450ms and the number of repeats from one to infinity.
Power Source
You can power the pedal using either a 9 volt battery or a power adapter.  

To install a battery first remove the four screws on the bottom of the pedal.  Attach the connector to the battery and make sure the battery is resting in the toe of the pedal, on its edge.  

To use a power adapter just insert the barrel plug on the end of the cable into the smaller hole on the left side of the pedal.  The polarity of the 9v connector is center negative, compatible with most common adapters.

The large button on the pedal switches it on and off.  A light at the top of the pedal will glow when the pedal is on.  The light is not a battery level indicator.  If you are using battery power, remember to click the pedal off and unplug both cables (IN and OUT) when the pedal is not in use.  This will extend your battery life.  Replace the battery if the pedal makes odd noises.  A battery should last one or two gigs, depending on how much you use it.  Many pro players install a fresh battery before every gig.  Of course, if you use a 9V power adapter this is not an issue.

Hooking It Up
Plug your microphone cable into the “IN” jack on the right side of the pedal.  If your mic cable has an XLR connection you may need an inline impedance matching transformer to convert your signal to high impedance.  No worries, it sounds a lot more complicated than it is.  Google it.  I use the Audix T-50K when I want to try a low impedance microphone.  Use a regular instrument cable to connect from the OUT jack on the pedal to the input jack on your amp.

If you use multiple pedals, place the MM Harpman pedal LAST in your pedal chain.
LEVEL – This knob adjusts the mix.  It blends your dry signal from the mic with the delay signal from the pedal.  All the way to the left (counter clockwise) will be all dry signal and all the way to the right will be all delay.

DELAY – This knob sets the time between delay repeats.  To the left is shorter time between repeats  and to the right is longer.

REPEAT – This knob sets the number of repeats.   All the way to the left is a single slap-back repeat.  All the way to the right is infinite repeats.
Playing the Pedal
I recommend you begin with all three knobs pointing to the left, in the 9 o’clock position.  This gives a really good fat tone, a thickener.  Click here to see a video of Nic Clark playing the pedal with those settings:

Next, try moving the DELAY and REPEAT knobs to the 12 o’clock position, pointing straight up.  This gives a very cool echo effect.  You can create an infinite variety of delay effects by adjusting the three knobs. 

One setting I don’t recommend is setting the REPEAT knob all the way to the right.   It causes infinite repeats, each one decaying and degrading until after a while you get a Pink Floyd-ish squawk.   I left that feature in the pedal because I thought some users might like it.  I never use it.
