may result in the pickup only being partially bonded
to the bridge plate due to insufficient coverage. One
indicator of good glue coverage is to see "oozed out
glue" around the entire edge of the transducer. We
recommend you carefully remove the system and re-
install.
MY GUITAR FEEDS BACK EASILY, ESPECIALLY AT HIGH
VOLUME
It is more difficult (but not impossible) to use the Pure
Pickup in very loud band situations, especially on small
stages. It is designed more for the acoustic musician
and the best possible natural tone. A sound hole cover
is the first remedy here and helps a lot. Our PowerMix
Pure System would actually be the best choice for high
volume situations.
Impedance mis-match issue: Acoustic amps and most
competitors' preamps are designed to work best with
undersaddle pickups or other very high ohmic piezo
pickups. They feature extremely high input impedance
(5-10 meg), which boosts the bass response. Most
competitors' pickups need this high input impedance to
boost their weak bass response.The Pure has a strong
low-end response. It is overkill to boost it.
The Pure sounds best with input impedance like 500 k to
1 meg. If you experience excessive bass response, plug
the Pure Pickup straight into the line input of a mixing
board -- you'll see that the excessive bass response is
gone.
