Soundhole pickups acoustic guitar amp are based on the same technology as electric guitar pickups. They detect the motion of the progress directly over the electric guitar pickup, which is commonly mounted in the soundhole (or, on archtops, between the bridge and fingerboard by effectuation of screws or a clamp). Since they ignore the motion of the top and the air, they are very immune to feedback. However, neither the acoustic guitars top nor one's fruit directly detects the progress motion above the soundhole, so these acoustic guitar amp pickups have the potential of reproducing an unrepresentative sound. This acoustic guitar amp was true of some early soundhole pickups; but more recently some remarkably good sounding soundhole pickups have embellish available. They still tend to have a somewhat fatter, slightly more electric sound than alternative transducers; for some tastes, this is a benefit.Since acoustic guitar amp do not detect air or top vibrations, soundhole pickups are favored by players who use techniques like right-hand tapping and harmonic slapping that crapper create undesirable tapping and squeaking noises that are sometimes excessively amplified by other transducers. They are also easier to install (and remove!) than most other guitar-mounted transducers.
The most popular acoustic guitar amp (and expensive!) help by far among professionals is the Sunrise ($170), which has been used by a rather impressive itemize of players (Leo Kottke, Phil Keaggy, Richard Thompson, Shawn Colvin, David Lindley, Michael Hedges, Alex de Grassi, Brooks Williams). In addition to the rather pricey pickup, the ``Sunrise sound'' requires that one use a broad quality, broad impedance preamp; depending on the model, this crapper add from $100 to $500 or more to the price.
