QDD A built-in distortion on Electric guitars that has been designed
on the Simulation of Historical Drive Sounds. In general, an
external effector has been used the Distortion effect because of
the fact that the external effector make more professional drive
lately. However, the QDD can make a precisely simulated sound
with very simple and economical way of installation and provide
a various distortion features that allows to increase your guitar's
commercial value. The way to install the QDD inside of guitar
can eliminate the cable noise. - Low profile / True
bypass @ Clean tone / Heavy Metal distortion / Improved overdrive
tone / No switch poping niose / Long battery lifetime
(3000 hours)
QTB This
is 4 step clean booster with passive bypass mode. The QTB has
4 different level of gain control - Low profile / True
bypass @ Clean tone / 0dB / 6dB / 14dB / 20dB No switch poping niose / Long battery lifetime
(3000 hours)
QTA / QTP This
circuit was inspired by the historical 5 band tone selector used on Vintage guitars. It has an
Active and Passive version. The QTA circuit has the gain control
and provides 4 different peak resonances. The low output impedance
provides operation stability and low noise level. The QTP has
the passive tone filter of the traditional RC methods that makes
4 different tones while very little level is reduced.
Easy installation on any passive pickup or active or bass guitars.
The system requires very little currents (QTA, QDD : 0.16 mA) from
a 9 V alkaline battery. Use the SMT and a closed Switch location
to make the installation easy. (more than 4000 hours in continuous use. -
workable voltage : drop down to 5 V ).
Applications
: Electric Guitar and Electric Basses
