Thanks all for your replies. I'll certainly be considering taking this further as my build progresses. I may not have expressed myself too well previously so to clarify ... My expression "wide e-bow" was meant to describe a dedicated pickup/driver pair rather than a hand-held device. I'm considering a rather radical fretless bass with a set of piezo bridge saddles AND a mag pickup (probably a humbucker) at the Musicman sweet spot. I was considering adding a pickup/driver at the neck end of the body, in order to keep the sustainer de-coupled from the rest of the electronics. With bass strings being nice and fat, with a lot of nice juicy magnetic material in them, and running at a low frequency,they may well take much less energy to get them going .. and .. well .. etc. etc. etc. I'm not worried about building the pickup. I've already got a couple of odd ideas I want to try out sop that I can get rid of a few of the 200 1/4 x 1/16 inch neodymium discs I bought recently .. but that's another story eh? Thanks again .. and now I think I'll drop back into lurk mode while I design and build that bridge ... Cheers, K4

Hi. I'm a noob, and a lurker up to now, and this amazing thread goes pretty much over my head .. I've read most of the thread over the past 4 days (or at least - those bits I understand backwards from now to around page 70) but it all gets a bit mind-boggling after the second day !! so I hope you don't mind if I jump in with a dumb question or two ... I'm part way through designing a piezo bridge, and I think a sustainer driver might be an interesting optional addition so ... Do you think that there still be problems with the driver interfering with piezo pickups the way it does with the mag pickups? Secondly, does a separate, self-contained, e-bow type, pickup/driver system need to have a pickup/driver pair per string, or could it be made to work like your current designs using full-width coils for pickup and driver? Would there be any downside to the "wide e-bow" approach to offset the fairly obvious upside of minimizing feedback/hum/fizz loops in the rest of the system?

Just in case its of use, here's a mail thread I had with Graphtech about the Floyd Saddles recently. The confirmed that I could make the thread public for the sake of anyone else who might be interested. ================= > > -----Original Message----- > > From: ..... > > Sent: Sunday, September 24, 2006 1:44 AM > > To: Tarina Dunwoodie > > Subject: Floyd Rose > > > > MESSAGE FROM THE GRAPH TECH WEBSITE: > > > > Name: Kevin Salt > > Comments: Hi Tarina, > > > > I get conflicting opinions from the musicians community so I decided to > > come straight to the source .. do you make Piezo saddles for the Floyd > > Rose tremelo? > > > > Thanks in advance, > > > > =========================== Tarina Dunwoodie wrote: > > Hi Kevin, > > > > I am sorry we do not presently offer FLOYD GHOST, still working on it!! > > arggg > > > > > > Tarina Dunwoodie > > OEM & Distributor Support > > Graph Tech Guitar Labs > > 1-604-940-5353 ext 33 > > www.graphtech.com > > > > ================ From: Sent: Sat 10/14/2006 12:07 AM To: Tarina Dunwoodie Subject: Re: Floyd Rose Hi Tarina, Can you then please tell me what item is represented by special order code PN-8080-00 ?? Thanks in advance, Kevin ================ Tarina Dunwoodie wrote: That is the Floyd Ghost, but it is not available. We sent out 10 sets as proto types but we realized the labour to make the saddles and for the customer to install them was far too much. We are still working on a better design to make these easier to make and install. Feel free to contact me if you have any questions. Tarina

Thanks Lovecraft .. in less than 15 minutes you saved me hours

I'm intrigued. I'm sure I've misunderstood things I've used as background reading, so please forgive a dumb question but ... If a standard LED has a Vf of around 3 to 3.3 volts, ans 2 AAs in series have a nominal voltage of 3V (more likely 2.8), why would you need series resistors to pull the voltage down in a parallel array? Surely the 3V is good to go already ?? I just tried it with a short array of 3 3mm red LEDs, and no resistors, and it seemed OK. It's particularly interesting to me because I just recently bought a fretless bass with the side dots in the "wrong" place (betweeen the fret positions instead of on them) so I was thinking of going LED at the same time as I sort out the dot positions. (OTOH - The foptic solution sounds like fun ....)
