Should the length or the quality of the used guitar cable
have an important influence on the sound of a guitar ?
Certainly not !
But unfortunately it's a fact, since the capacitance of the connected cable and the inductance of the magnetic pickup form a tuned
circuit and its
resonance frequency happens to be mainly dependent on the value of the cable capacitance.
In addition, the capacitance of the cable forms a lowpass filter in conjunction with a
dimmed volume pot and thus affects the function of this control.
More information on this subject can be found here.
("The PURR") tries to offer an alternative.
It's an external solution, without any
need to modify the guitar itself, with an internal 9V battery as its power supply.
lower end of the guitar strap,
will be connected to the jack socket of the guitar via a
preferably very short cable, a patch cable for example,
Its output will be connected to the amplifier or
the effect chain
via the usual guitar cable.
What length or electrical quality (capacitance) this cable now has is relatively unimportant, it has no influence on the sound any more.
By means of a 10-stage rotary switch various capacitance values can be placed in
parallel to the guitar output / the pickup.
Thus cables of different lengths or qualities can be simulated. The resonance frequency of the pickup can be
adjusted to one's

the original amplitude of the guitar would not be sufficient to do so.

Additionally / alternatively, the unit can be turned off by a toggle switch on the back.
