unpadded to improve coupling between the pickup and guitar
body. Because the M1 reads the top resonances that provide
depth and warmth, using cork pads may dampen this sensitivity
and adversely affect the pickup’s responsiveness.
For permanent installations, be sure to secure the wire with the
two self-stick wire clips provided so that it does not hit the inside
of the guitar during stage movement.

4.1. Plugging in: The M1 will plug into practically anything with
good results. Low impedance inputs such as those found on mixing
boards will flatten the sound and reduce the pickup output. High
impedance devices such as active direct boxes will capture all of
the M1’s nuances. Our Para D.I. partners well with the M1 due to
its high impedance, clean gain and EQ capability.
Note that the length and quality of your cord will have a large
influence on the sound. This is because passive magnetic pickups
interact with the cord capacitance to create a frequency peak
that is a distinctive part of the tone. Long cords move this peak
frequency down, and create an edgy, “electric” tone with more
midrange. Short, low-capacitance cords move the peak up, creating
an airier, more acoustic-sounding tone.
These are simply general guidelines; experiment with different
cables to determine the best match for your guitar and equipment.
4.2. Experiment with pole piece heights: The pole pieces on
the M1 are preset (for bronze acoustic strings), but this is just a
starting place. They are adjustable with the 3/32” Allen wrench to
obtain the optimum balance and tone. The height of the pole
pieces relative to the strings will have a profound effect on the sound
