1) LOAD RESISTOR INPUT (Combo only)
Guitar pickups have different output
voltages. Using the load resistor plugs supplied with your combo amp, you can match
your pickups to the amp's input.
STANDARD ELECTROMAGNETIC PICKUPS
Convertible amps have 4.7 meg-ohm input jacks. Some players prefer using no load
resistor plug because they want the brightest sound possible and 4.7 is a good match
with their pickups. You should experiment with the two load plugs provided to find your
favorite setup.
It is recommended that the input impedance of the amp be 10 to 20 times higher than
the pick-up output impedance to avoid excessive "loading".
UNIOUE DESIGN PICKUPS
LOW IMPEDANCE PICKUPS: To optimize signal to noise ratio, input impedance should
be fairly low - typically 100 to 10k ohms. Try the lOk330pf load resistor plug for great
tone and low noise.
PIEZO TRANDUCERS
(built in to acoustic guitars): To avoid loading down Piezo
pickups, the input impedance should be high. Most players like the sound with these
pickups using no load resistor plug.
ELECTROMAGNETIC ACOUSTIC GUITAR PICKUP:
To get a warm, round sound,
many players like using the 1 meg load resistor plug, It gives a smooth high end and
quiets the signal.
2) MAIN GUITAR INPUT:
When using only one instrument, this is the only jack that is
live.
