DRAGSTER™ LOAD CORRECTION
The Dragster is a load correction device designed to restore the full, rich tone you lose
when you plug your guitar into a buffered input such as a wireless system. Dragster makes
passive pickups “think” (and sound like) they’re connected directly to an amplifi er by
simulating the impedance of an amplifi er by allowing you to adjust the load on the pickup.
Guitar amplifi ers are typically high impedance inputs and pickups sound their best when
connected to an amp. Buffered inputs are typically low impedance and pickups can sound
“thin, weak and brittle” when connected directly to them. Examples of buffered inputs
are wireless transmitters, digital effects, mixers, sound cards and recorders. Dragster is
inserted between the guitar and the buffered input. The thumb wheel lets you dial-in the
perfect impedance for the most natural sound. Result? Your guitar tone regains it’s warmth
– it feels ‘right’ again and your performance sounds great!
Dragster is a compact, passive device featuring 1/4” connectors, lightweight aluminum
construction and a single ‘thumb wheel’ control. The Dragster may be sewn onto a guitar
strap for use with a wireless transmitter, or be hidden away on a pedalboard.

A Classic Guitar Tale
Player connects fi ne guitar to great-
sounding amplifi er and experiences
tonal bliss. Time goes by and effect

USB Interface
pedals and wireless systems get
inserted between the guitar and amp.
Player enjoys the new tones from the
pedals but misses the pure tone of a
direct connection to the amp. In order

to get back that tone, some players
swear off pedals and wireless entirely
while others invest in “bypass”
boxes. What these players are
experiencing is an impedance missmatch between their passive guitar
pickups and the buffered inputs
found in many electronic products.
