CONTROLLED PICKUP SWITCHING

 

 

This feature is advanced and can be disregarded if you prefer to use a standard wired guitar with 

a mono cable! 

 

Why ? 

Go from a clean sound with your neck pickup to a distortion sound with your bridge pickup with 

one step on your MIDI-foot controller only. 

 

How it works ? 

The input jack on the front panel of the Quad15 is a stereo jack connector ready to accept two 

signals, where one pickup signal at a time can be routed to the preamp via a built-in relay. Press 

down the “Input” selector on the front panel to switch between the “Rear” and “Front” signal 

from the front panel input jack. 

 

 

 

 

 

The simplest way to modify your guitar for programmable pickup switching with the Quad 15 is shown above. A stereo 

jack cable is required along with two volume pots or one double pot. To be able to use your guitar with standard mono 

input cables for other amplifiers, there are several options to incorporate a pickup switch in your guitar as shown in 

the following examples. 

 

IMPORTANT: To use this feature, make sure that NO cable is connected to “Input Rear” on the rear panel. (Pre-gain 

loop is not possible). NOTE that MIDI-controlled pickup selection requires custom-wiring of your guitar, which might 

require a skilled person to do the modification.

 

 

NOTICE: When selecting “Input Rear” on the front panel to connect the ring from the “Front input” to the preamp, it 

will still be the “tip” of the “Front input” jack that is fed to the buffered “Guitar out” jacks on the rear panel. 

 

See block diagram on page 27.
