MM Boost Docs

The MM Boost Pedal is specifically designed for blues harmonica, giving more bottom end and more breakup and grit at any volume. It reacts to the pressure you put on the microphone.  This pedal is true bypass when switched off.  

SETTING IT UP  

There are two ¼ inch phone jacks in the pedal, one marked MIC for microphone and one marked AMP for amplifier.  You will need two regular instrument cables.  If you are using the MM Boost on a pedal board with other effects, we recommend you place the pedal at or near the end of the chain to gather your signal into a fat articulate stream to be presented to your amp.  

To power the pedal use only a filtered, regulated 9 volt DC adapter with center negative polarity.  The pedal does not have provision for a battery.  We recommend the 1Spot power adapter from Truetone.

Be sure to carry an extra extension cord in your gig bag. 

PLAYIING THE PEDAL  

The MM Boost Pedal has two controls:  A knob controls the level of the effect, and a large sturdy foot-switch button turns the pedal on and off.  When the switch is off the pedal is in true bypass mode.  

The MM Boost pedal causes overtones to cascade in the input sections of your harp amp, from one to the next.  It will work with any amp, even into a PA system, but it works best with a tube-driven harp amp.   

Some players use the boost pedal to punch up their solos.  Others leave the pedal on all the time, usually at a low level.  There are no rules since the pedal is so versatile.     

When you first get your new MM Boost pedal please resist the urge to hook it up right away with all the settings on the amp the as they were before, and crank up the pedal and blow.  You’ll probably get immediate feedback.   

Lots of us play our amps on the verge of feedback, and the small amount of gain in the MM Boost Pedal can push your signal over the feedback threshold.  You’ll might need to turn the amp down a bit.  Don’t worry, you won’t lose volume.  In fact, you’ll likely get more.  

There are three knobs that control the behavior of the pedal:  The Level knob on the pedal, the volume knob on our microphone, and the volume knob on your amp.  Use all three to dial in the crunch and thump your looking for.  

Start with the Level knob on the MM Boost Pedal all the way down (counterclockwise) and with the volume knob on your amp low.  Experiment with different settings for all three controls: your mic, the pedal, and your amp.
