Piezo for EUB

saxnbass · #1 09-29-2006, 10:55 AM

I got an EUB and I'm going to mess with the bridge positioning to see if it helps with the sound any, but if not, I'm going to be getting a new piezo for it. Any suggestions for a good Piezo for under the bridge on my EUB?

The size (height, width, and style) the bridge and body composition will dictate which pickup could be successful with your EUB. Give us more info.

I believe there was a thread on this not long ago, doing a search would probably be rewarding.

It's a 42" scale (3/4) Ergo EUB 4-string made of Honduran Mahagony. That's about all the specs I have about it.

I've had great success with these home-made ones on URB's and EUB's - www.fittell.id.au/piezo

Does anyone know if the piezo tabs can be cut down or if anyone sells smaller tabs?

Thanks,
S

Why do you need smaller ones? I find the 3/8" x 1" just about right for going under a bridge foot. I've also tried the larger ones that span across both feet - these would be good for upgrading a Palatino.
I haven't tried cutting one down, but I don't think there'd be a problem. I'd probably put a little insulation tape over the cut before adding the shielding foil.

I need an individual signal from each string for a project I am working on. Thanks for your response. Suppose the only way I will know how well it works and holds up is to try it.

Peace,

The K&K Sound Pure Classic guitar pickup has four of their small transducers, it's an economical ($107) way to get four compact sensors. From your posts I am assuming the Double Big Twin's 3/4" size transducers would be too large, though I'm sure I could get a custom setup with them cut narrow, such as is used for the rockabilly fingerboard transducer.

I've done a lot of experimentation with transducer positions and bridges, feel free to email me if I can be of any assistance.

Those piezos are only $2 each, so trial & error doesn't break the bank.
I was going to make a 4-pickup bridge for my EUB, but when I tried a piezo under the foot it sounded so big and balanced I stopped right there. I'm still planning to put 4 piezos under the bridge of my fretless Jazz.
Are you intending to process the pickups separately or just parallel them together? An advantage of running a few in parallel is that it drops the impedance down to a more reasonable range.

I'd suggest using small PZT crystals instead. More output, for one thing. I found a vendor on eBay that sells a variety of sizes:

Interesting. Which ones do you use? Is there a trick to connecting them? Do they need complete shielding like the piezo films?

TheSuzie · #12 10-26-2006, 07:49 PM

I would like to hear about those too.

I have multiple applications for both EUB and BG. One is to be able to buffer and adjust the individual strings to achive an even (or intentionally uneven) amplified response. Another is to provide individual string outputs to drive various synths and/or effects. Shhhh - don't let the DB purists know...
