Hi folks,

Back to an old topic posted in the last (RIP) forum. It was about an audio wire pickup that could be cuted to any lenght. I need a pickup for an incoming 8 strings fanned frets acoustic guitar order and I don't found any pickup that long( 3 3/4").

any ideas are welcome

Monsieur Lamour!

Mon Ami!
that's about it for my French!

But I do know about the "audio wire pickup", since I posted that, and I have used it quite a bit.

First, Ben is right that Pick Up The World and probably other places will make you custom-length pickups, and this is the easy way to go if you aren't inclined to play around with electronics.

If you like to do it yourself, it's not too hard...well, actually it's pretty tricky at first.  First, the material is called "Piezo Co-axial Cable" (or something very similar.  I get it from Images SI, Inc., and it costs about 15 US Dollars per foot...cheap!  Here's the link to their web page with it..just scroll down til you see it listed: http://www.imagesco.com/catalog/sensors/piezo.html

You will want to either have an internal/onboard, battery-powered pre-amp or some kind of external pre-amp that gets plugged into directly with as short a chord as is practical.  For an internal/onboard pre-amp for piezo pickups, I use a Bartolini model that is very small.  I think the model number is MPB-1, or something like that. It's for combining a magnetic and piezo signals, and I just use the piezo channel. I get it from Allparts (http://www.allparts.com).  You need to wire the battery pack to it, and the pickup element, and wire the whole deal to an endpin jack.  Lots of work, but can be pretty fun.  The piezo cable material comes with a plastic insulation/coating that has to be removed, which is a bit tricky, and you need a special, tiny, rounded-end router
bit to shape the bottom of your saddle slot to perfectly fit the cable.

Yes, complicated...but sometimes the only way to get what you want is to make it yourself.

Good Luck!

Fred

Merci Benoit!

I have contacted PUTW and I've dealed with them.

Thanks Fred,

That's what I was speaking about! I will try this Piezzo material in any way (for a non linear bridge shape) in combinaison with a fishman preamp I have for long time. I 've made an electronic high school when I was () young. I love to play with that kind of stuff. I've tried some PVDF materials but it was not good enough for high quality sounds.

cheers
