Extension $
Ken
Is it really as labour intensive as they say to make a proper extension? I saw you said you were making them in your shop now, did you make the one for the hart? It looks great. |

All my extensions are by Arnold or Jeff so far. Compared to other extensions I have seen, these are the best so far. I have tried other extensions from various basses that come thru the Orchestra and basses that come in here and sometimes, I feel sorry for them. The one with those 'easy to install' Capos cannot be flipped with the back edge of your fore finger on the fly. More likely with these and others with sharp points, you will hurt yourself. Using a full hand or two hands even to hold your bass and flip or close a capo makes a 5-string bass look more appealing. |

Woops
I guess I read than incorrectly, still a nice extension though.

No one noticed that my odd D extension is actually made from a single fingerboard with the extension cut out.
Half size string length with added 2 notes on a 1/8th size bass. Tuned A D G C with a low G. Bass bar and soundpost modifications were necessary. The bass sounds great. |

That's... unusual, at least!
Got any more pics? What do you use the bass for? |

D extension
Lemur had this bass for a while:
http://www.youtube.com/watch?v=Q2wWDdPSvnQ It's the only other D extension I've seen. |

If you have an Extension, it should be to a 'C' and nothing less. Why bother at all putting something on? I can tune down and back up as easy or more to D or Eb without any alteration to the bass. I did a rehearsal last week playing the New World Symphony, the 3rd time in a year as I did it with two other Orchestras last season. In the beginning are two low Eb's and I used my C-Extensions set at first to Eb for the start and later down the page I closed it to E for the rest of the piece. Last week I just tuned down to Eb for the start and tuned back up with no sweat being that it was just a rehearsal, leaving my bigger basses at home that I have extensions on. I think putting on a D-extension is like doing it half way. It makes no sense to me and if you can't change back and forth while playing without interruption, it's not a workable extension in my opinion. |

Well heres how it went:
I started of with a 1/8th size bass. (about 80cm i think?). Its my feeling that at least for me qualitatively, a half size string length is the absolute minimum. So 97 cm. In order to achieve this with the same neck heel note, I had to extend the string length in both directions. I have a D extension on my Romanian 1/2 size with 97cm string length so this bass was made to match. BTW the D extension with the open A and D is great. The notes reinforce and actually swell when in tune. Extra long fingerboard. Normal width tapered in the back to the neck width. With one tuner turned around and most of the bottom curve to the pegbox taken away, the two extra notes can be fingered in one easy motion. Since moving the bridge down sets the bridge on a stiffer part of the top, some internal mods were done, and a lot of tension was taken off with a very high French style tailpiece. This is a low tension system. Sound post is above the bridge. To bring out the upper bass resonance peak when playing acoustically a hole was made in the shoulder to compensate for the small cavity (and top and string length) that is expected to reproduce the same tuning as a normal instrument. In a smaller system dealing with the same low tuning, the alignment changes and the bass is much more critical and sensitive to small changes. The bass was made to amplify, but has a well balanced sound acoustically if not as loud. The goal was to make the bass work correctly "mechanically". I found that by only amplifying just the missing parts of the lowest octave it can sound like a well balanced normal sized instrument played acoustically. Mostly I play fully amplified though. As far as comfort, It balances well and the feel of the board and the string spacing are even better than my 1/2 size. Oh, one last note. Its now tuned a d g c with a g extension. so I only lose 3 half steps. Evah pirazzi c was the only string I could find that wasn't thin and twangy. Same thickness as the spirocore G. A pleasure to play. The bass is now antiqued black like the bass I bought from Ken in 84. It was immediately taken more seriously as people tend to hear with their eyes. |

It is is a bit more difficult, but nothing that a long nose plier couldn't make much easier.

Can you explain why you think the post above will cause trouble down the line?

Was the post perfectly fit to begin with? If not, it is already damaging the Top. Possibly it will crack the top or poke thru it. I have never heard of the post being above the bridge. Playing a 1/2 sized basses with an extension and tuned up a 4th is a Tenor bass of sorts, not a double bass. So, everything is weird about this. Post some pictures so we don't all get a headache trying to imagine this. It is way off topic anyway so we might as well end the story with some visuals.

Is it off topic then? The soundpost of course was refitted. Maybe you thought I would have just moved it as it was after doing all this work. Where's the argument here? I see none. I think that it arises from its unconventionality. Haven't jazz players used extensions by the way? Is this forum only for classical bassists. Is it only for traditional techniques? is it open minded? I would hope so. I would hope to find any interesting or even controversial information in a forum such a this. Is that not what a forum is about? We can all learn something here. The bass works well as a contrabass too. And like I said, as a tenor bass, with the extension it only loses three 1/2 steps. |

One thing, when I say above, I don't mean clear of the foot. Same position as what would be called below.

Finally finished extension for my Geiger bass!
Slideshow: http://s389.photobucket.com/albums/o...view=slideshow I still haven't mounted it. Also need to smooth out the varnish a bit. This is the only one I've made from scratch. I ended up with just enough room to bring the string back over the scroll and over a second smaller pulley which sends the string down to the "A" tuner. Ken, you make a valid point about the sharp ends of the fingers, but the example you saw was very early work. For many years now I have a greatly improved leather wrap, including a larger radius at the end. If this is still not enough, I can on special request wrap a thicker band of leather and make an even softer edge, but everyone out there who uses them seems perfectly happy the way they are. There is an aesthetic thing here too. Some people prefer so see less bulk on their scroll! |

Looks great, I was thinking a two piece extension would make routing the string around the scroll easy. Glad to see someone implement it the way I imagined. Here is an extension I finished last night.
