Each guitar that I use on-stage is equipped with a Sunrise
magnetic pick-up and an
L.R. Baggs I-Beam . Both
pickups are wired to a L.R. Baggs I-Mix stereo preamp inside the instrument.
Tips and Tricks
Acoustic amplification and pickup technology has also gone through some
incredible breakthroughs. People always ask, "What's the best
pickup." Or ask, "What do you use?" I encourage people to
get out there and play as many different systems as possible. Tone is in
the ear of the beholder! I personally have not found one pickup that does
it all. I like to use a combination of a magnetic pickup with a soundboard
transducer.
A magnetic
pickup gives more of the fundamental note and has a quicker attack.
Because it senses primarily the vibration of the string, it's best suited for
loud volume situations and will resist feedback the best. In other words,
a good choice if your playing in a band setting. It also will reproduce
notes lower in frequency than what the body cavity of the instrument will
reproduce. This is useful for lowered alternate tunings. I've also
found a magnetic a good choice if your playing in a wide variety of rooms with
different sound engineers. You really have to try hard to make it sound
bad. Some tips on equalizing a magnetic for optimum performance: Try
scooping out somewhere between 300hz - 400hz. Boost a narrow bandwidth at
63hz - 100hz for more thump. A slight boost around 6k - 10k will add some
sparkle if it sounds dull in the mix. Once again, use your ear!
A soundboard transducer senses
more of the body vibrations of the instrument at all three axis's (top, back and
sides). While they behave similar to a microphone there more resistant to
feedback. Keep in mind, they'll still feedback if pushed hard enough.
They're a great choice for reproducing more of the authentic tone of the
instrument and have a wonderful high-end definition. I tend to notch out all
frequencies at 150hz on down to take out the boominess as well as add of few db
of boost around 8k - 10k. When blending both pickups together I get my
low-end from the magnetic and the mids and highs from the soundboard transducer.
In regards to under the saddle
piezo type pickups...I really have not heard one that I like. Their prone
to string balance problems and tend to have a harsh 'quacky' sound that is
instantly identifiable. While they are not my preference I encourage
players to check them out.
