Fretless 7 string chambered Headless bass

(like the 5 string, but with 2 more!)

--------- o ----------

 

After a conversation I had with Steve lawson early last year (Bassist/Guitarist scribe, awsome solo artist and general all round good guy...can I have my next lesson cheap?) we were discussing what my ultimate bass project would be. I had always felt that a six string fretless is just about as exclusive as I would go. But Steve pointed out that every one and his mate makes "sixers" these days and that they are pretty common. So I said "How about a seven?" thinking that would be it. Then Steve said "How about a seven string....headless! No one makes one of those." (Except David King at BGS). He also mentioned that he'd love to try my 5 string headless as a fretless. I wasn't about to rip the frets out of my main working bass. But I could build a 7 string version of it. Same body shape but adapted slightly to work as a seven. So it was settled, but to be frank I didn't even think it was possible. A headless bass requires very specific hardware and if Status, ABM or Steinberger don't make it then forget it, it isn't going to happen. So I sat on the project for about six months.

Then I noticed that Rob Green was fitting individual tuner/bridge blocks on his current range of headless basses. If I asked Rob nicely enough I could use 7 of these racked together to make a complete unit....Hmm just the headpiece to worry about.

I spoke to Arron Armstrong about the pickups (He thinks I'm nuts...so does my wife, they could be right. I am starting to think that "hobby" is latin for mental illness!) who said that there should be no problem. So it looks like this project is starting to happen. I have a lot of the wood, I have the concept, the bits are nearly ordered....I best get sketching! ( 10/08/00)

 

The body shape will be an adapted version of my 5 string headless, with a few improvements.

If I get time, I want to fit green LED dot or fret markers to the fingerboard.

The woods I have selected are a sample from all my previous basses.

---------- o ----------

The wings are a 5 piece sandwich made from 3 diferant woods. Cocobolo, maple, wenge, maple and then cocobolo.

The Neck will be a 7(ish) laminated all through construction, made from Maple, Paduak and Walnut.

This Bass will be chambered (I have to get the weight down some how!) and this time it will have the fancy sound hole which I left out of my 5string headless.

The two most comon responses I get from my web site are for the 5 string headless. They are: "Why didn't you use that fancy F hole", and "did you make the body hollow".

Answers: The body is hollow, but the hollow chamber was only 1" deep (I goofed with my measurements). I had to really rush making the 5 string, my wife was pregnant and due only 10 weeks from when I started the project. I wanted to get the bass finished ASAP because I knew I wasn't going to get any time after! I also forgot to load my camera with film and missed the opportunity to show the hollow sections being layered together. The rosewood top was 3/4" deep and way too hard and deep to cut a decent sound hole and the chamber was too shallow.

I will be using the same 3 band Bartolini circuit I used before, but I won't bother with piezos, I'll leave that to specialised basses from now on.

---------- o ----------

I fancy a single coil pickup and a wide Music Man style humbucker pickup with matched outputs. I find the wide spacing of the humbucker helps with the Coil tap switching. I find that with a narrow humbucker (like my 5 string) a coil tap sounds like a quiet version of the same pickup. I assume this is because the two coils are effected by their close proximity to each other. Both pickups will need to be custom wound. Probably fitted with my infamous 5 way rotary switch, although I didn't fit one to my 5 string headless, maybe I'll use the same wiring option. It really depends on how the pickups are made.

The centre section is all through and is made up from nine laminates of quartersawn Maple, Paduak and Walnut.

The Fingerboard is Rosewood and is very straight grained. It is also very thick so I won't have to use much of a neck angle.

After carefull planning, I shouldl be able to yield 2 seven string headless necks from this one blank. So I may build a fretless 7 and a fretted 6 or 7!

I have bought a 2 way acting truss rod and a pair of graphite strengthening rods (hey it is a 7 string!), which were kindly supplied by Rob Green of Status-Graphite.

Here is a shot of my 5 string headless with one of Rob Green's new individual bridge/tuner blocks along side to compare. The new unit is the same length but will have a more narrow width across the bass when using the same string spacing. Thanks Rob for 7 of these, without them this bass just wouldn't have happened. The beauty of these units are that they combine a individual bridge and tuner into a single unit. I just rack 7 together and I don't have to source a 7 string bridge and a 7 string tuner block.
