Cirrus onboard preamp

Post by owl199 » Mon Feb 22, 2021 5:04 am

Hi all out there.
I am new in this forum so I hope not to make too many errors on my first trial.
I bought in 2003 a Cirrus 4 in USA and received it in Italy, where it did his fine work until 10 days ago where the onboard preamp died.
I thought to install an aftermarket preamp and try to repair the original instead to send the whole guitar around the world, so I purchased a Glockenklang 3 bands 5 pots and went to install it, when I realized that pickups have 3 and not 2 wires coming out.
There are a white shielded and a red unshielded wire each pickup.
Can somebody help me finding out how the wiring of those pickups are intended to work?
Many thanks all of you!!!
Tiziano

Hi Tiziano

The red wire takes a power feed from the batteries.

VFL pickups are true actives in the sense they need power to work.

Divert power from the battery connects, pass it through the pickups then return it to the preamp.

Thanks Kodiak, it´s a confirmation of what I supposed, actually I already wired them that way, I just need to insert batteries and test it.
Once again:Thanks!!!

Unfortunately still silent, will have to extract and check the pickups.
Can´t imagine that both went fried at once...but!
I am crying for having to disassemble my good old Cirrus, and moreover I hate not having it more like original.
Amp ist tested working, cable is tested working, new preamp, so it can be only the pickups.
Have to lookout for new Pups, I guess.At least I have a wide range of choice since I already changed the pre, just look to find something fitting in the cavities, I dunno want to work on the body, is a peacock blue, and the finish laquering is extremely delicate to handle.
Will come back once I solved the problem.

Might be something very simple like the battery clips, the ones Peavey used were very flimsy.

Looking forward to hearing " it's Alive " :)
