Thanks for the responses. Yes Mark, I was trying to draw in people who like to argue or observe other people arguing - that seems to include most people.

UB Ed, I did wade through all the threads you linked, and found brief references to Art Thieme using a "Helpinstill" and Songster Bob (I think it was) using a "Woodpicker". It seems that they're not very popular around here.

Are transducer and contact synonyms?

Spaw, I've looked over the PUTW website a few times and am still confused as to how they basically work. The thin rectangular shape suggested to me that they are a variety of under-the-saddle pickup - but it seems that you can also tape and untape them to the top if you want to? Or is that even the standard way to use them? Would you call PUTW a contact pickup? I tried reading their preamps page and didn't understand a frigging word.

What's a preamp? Will it fit into my case's compartment? Do you have to be smart to use one?

WS, Grab, and Rick: when you talk about finding the perfect place to stick the thing on, is this a one time experiment, or does it take a lot of time and trial and error every time you put it on? I'm wondering if it would be feasible to switch the pickup from guitar to fiddle and back again in the middle of a show while casually discussing my navel. Or do people even shift around the pickup on a guitar between songs to make different songs bassier or treblier?

Use small words, I've spent most of my life trying not to think about this kind of thing...

Thanks, Marion
