Info On Prs Sweet Switch

[tubescreamer]

Hi!

what is the function of the old PRS sweet switch? How it is connected?

Thanks

If I remember correctly, it came about with Santana playing live switching to a radio transmitter instead of a long cable. The change caused the circuit resonant frequency to shift, which altered his tone (long cable = extra resistance, impedance and soem capacitance). The sweet switch involved a small resistor and inductor which mimicked the residual effect of a long cable so he could nail his tone even when using the radio mic. PRS very soon traced it back to a perculiarity of the pickups he was fitting at the time, modified them to eliminate the problem and declared the sweet switch redundant.

For a simlar idea (complete with component values), with a lot of extra tech info, check out Jack Orman's Guitar Pickup Simulation article in the AMZ Lab Notebook.

It seems like the simplest method would be routing the hot signal from the pickups through a mini-switch before the output jack (or the volume knob) that was pure signal when "off" or run through a capacitor to bleed off a little high end in the "on" position. I'm planning to go with this on my current project as hitting a switch quickly to get a smoother tone is a lot quicker and takes up less control space than a regular 1-10 control pot and knob on the face of the guitar.
