Description
QTA,Quadra channel Sound Controller
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.
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 5V).
