  1. I don't believe you'd need six sensors and six amps. If the six coils are in parallel they could easily be turned off by an on/off switch. I realise that they may have to be staggered, perhaps a humbucker kind of thing with three coils in each single coil. The driver I have made is from an old single coil pickup, and bending was sustained just as well as the single notes. I think this is because the poles are fairly close together and its not like its a beam of magnetic energy shooting out from the pole. Thats it, I'm going to make a triphonic coil and if thats a success I'll consider making a hexaphonic one. Didn't you all find that you had strings being magnetically induced into vibrating that you didn't want to when you were playing on some other strings?
  2. I'm using old strings off my Warwick bass. I do realize that the tension of bass strings is quite a bit more than nylon strings, but after extensive testing and then stringing it with the bass strings and playing it for a while, the neck was fine. It was quite lucky, I was expecting it to bow crazily or even snap. That is what I mean by "yes it does work". Now, what I meant by "just not the third fret" is a reference to what I was talking about with the uneven fretboard. Although it technically doesn't have frets, the third fret position on all strings hums because of the unevenness. It is the only fret position to do this. You refer to it as 'that "bass"'. I prefer to call it a 'fretless short scale acoustic-electric bass'. Edit: I neglected to capitalize an 'i' Edit 2: I found another one.
  3. I don't know if anyone has ever mentioned this, but I think someone should. 30 AWG copper wire is 0.338 ohms/metre (http://www.powerstream.com/Wire_Size.htm) and using maths we can work out that you need approximately 23.669 metres of wire for an 8 ohm coil. This just takes the guess work out of it, I mean, dozens of places I've read that you do 'a hundred or two' turns. I vaguely recall talk of six coils, one per string. I do wonder where that discussion led, but you'd need approx. 142.012 metres all up (23.669 m per coil). Assuming they're coming off of the one amp and they're in parallel (to be able to turn them on and off), when only one coil is turned on it would have immense power pointed at one string (rather than the big six string drivers where the power is applied to six strings). Power equals voltage multiplied by current (maybe). The current will be divided between all the coils which are on, thus the more coils you have turned on the less power each one puts out but the total power is the same. I think three coils would be easier, especially if you use the pole pieces from pickups as the core (winding 24 metres of wire around those would make them big). Anyway, I hope this hasn't been all discussed before otherwise I'll get yelled at. Love From Samuel.
  4. Wow, I just realized there was a muffin, toast and a banana. And a turkey! It never occurred to me just how food orientated Sublimarine is. It wasn't really a food theme though...
  5. If anyone is wondering about what happened to the first El Madonna http://www.sublimarine.com/em1/P1010058.JPG http://www.sublimarine.com/em1/P1010059.JPG And let's not speak of El Madonna II
  6. I made it. If you like that muffin with a face you'll like the song. Talking Muffins found on Sublimarine X
  7. Late last year the music department at my school gave me a free nylon string acoustic guitar... http://www.sublimarine.com/em3/P1010747.JPG http://www.sublimarine.com/em3/P1010748.JPG The person who correctly guesses why wins a prize. So I set out on a journey with my dremel clone, sander, drill and jigsaw, a journey to fulfill my dream to have a fretless short scale acoustic-electric bass. http://www.sublimarine.com/em3/P1010749.JPG http://www.sublimarine.com/em3/P1010790.JPG http://www.sublimarine.com/em3/P1010796.JPG http://www.sublimarine.com/em3/P1010797.JPG http://www.sublimarine.com/em3/P1010801.JPG http://www.sublimarine.com/em3/P1010805.JPG http://www.sublimarine.com/em3/P1010818.JPG http://www.sublimarine.com/em3/P1010841.JPG http://www.sublimarine.com/em3/P1010848.JPG http://www.sublimarine.com/em3/P1010824.JPG http://www.sublimarine.com/em3/P1010829.JPG http://www.sublimarine.com/em3/P1010838.JPG First I ripped off the top, I mean, who needs that anyway. I bought a huge piece of some kind of board from Mitre 10 for about five dollars. It was some kind of pretend wood. It has great tonal qualities, I'm sure. I unfretted it and sanded it all down too. I knew this thing wasn't going to take normal bass strings unaided, so I beefed it up with some bracing (especially around the neck). The hole in the back is for restringing and access to the electronics (a twenty dollar staggered bass pickup, a volume control and a rotary switch with various different capacitors going to ground for tone). Due to the nature of that hole, I was forced to leave the pickups in during painting. I also cut a slice out of the headstock and glued it back on, and I cut the ends off the tuning peg holder thing, cause I only need four strings. I filled in the frets and the writing with epoxy. Damn that epoxy, it caused me so much grief. I was fixing up the second 'a' in Madonna and I mustn't have mixed the epoxy properly and it wouldn't cure and all other problems. I ended up having a fairly uneven fretboard (third fret dead) from sanding. I also lost most of the two n's in Madonna from trying to fix the third fret. I took it in to a fancy Spanish luthier and they said they'd fix it for 200-450$, I laughed at them and went to a music shop near my house where I know the guys and now it's getting flattened properly for free. And I also scored another nylon string acoustic guitar, this one was only kind of broken though. I wonder what I'll do with that... I applied the primer with a roller, and airbrushed the blue. And here is the (almost) finished product, all that needs to be done now is get it back from the guy who was flattening the fretboard. I'll probably have to redo the 'El Madonna III' in it. http://www.sublimarine.com/em3/P1010854.JPG http://www.sublimarine.com/em3/P1010850.JPG The finish was looking good 'til I airbrushed the clear coat on. In those pictures the volume and tone controls aren't pushed through, and I haven't decided what kind of knobs I want. The input jack is on the side. Due to the bubble sound holes, it isn't acoustically amplified that much. Well, a bit but not enough to compete with a normal acoustic guitar. If you're still having your doubts, yes it does work, just not the third fret. And if you're slightly confused by the pictures in the pictures, go to www.sublimarine.com. And that's my story.
