Back in the shed today. Mowing lawns, spraying clover, fixing leaky VWs and... finally doing some bass work.

Image

Took me a couple goes to get the first PU wire hole right, but once I'd done that one, I got the other 3 right (or close enough) on the first go. :)

Image

I was worried about what I'd do with the wire, but it turns out I could tuck the wires away quite neatly. Yay!

Image

As you can see the control cavity is rather snug. I think I'm going to go; Vol, Vol, Piezo blend now. Should give me a bunch of different tone (myth) settings and get rid of the issue with the double gang pot I showed you last time.

Image

In the mean time, I'm wetting the neck down and knocking down the grain, ready for hand rubbed poly.

Image

The vic ash the neck is made from is a really open grain, so you have to do this at least 4 times to get it perfect. The Jarrah board, on the other hand, is great and doesn't yield much grain standup.

Decided having a thousand bits laying around was risky for the damaging the finish. So I screwed them to together so I can damage it more comprehensively. ;)

Image


Image

As per usual, there were the usual assembly bit of fettling needed. The neck plate isn't torqued down tight yet. I'll do that once I get the neck on. I'm on my 4th coat of wipe on poly. It's looking good. I'll post some pics of that soon enough.

K, so for my next trick...

Should I wire my HB PUs in...
1. series or
2. parallel?

Why not both? 2-way mini switch ...

Try both ways and see which way works best blended with the piezos ('cause there is no room for a push-pull pot in that cavity you made!)
:yep

I decided a while back that I wasn't going to do that. I just don't think I'll use that option enough to justify more controls and the like. I found on the liquidambar 5 string, that I just used one of the two depending on the strings. For flats, paralell, but for roundwounds, series. So maybe I'm answering my own question with tapewounds...

In other news... I put it together last night. :)

Image

Even my wife noted just how much larger than a regular bass it is. Due to extra width added from the finish, I'll need to do a little shimming on the side of the bridge block, but no biggy. Then it's time to start shaping the bridge and get some strings on it.

Back on the bench and checking a few things out...

I got the output socket on last night and started messing around with PUs. Just for a laugh I tried the barts I've got too.

Custom nordies...

Image

Barts...

Image

The barts are much taller than the Nordies. I'm leaning toward them at the moment, but I have one little issue.

Image

Basically, when they poured the epoxy into the case, it ended up high on the bass side. I've shaved some of it down a little, but it still needs to go lower.

Image

I'm not above filing it down. My only concern is that the B string will end up really boomy with the PU so close to the strings. Thoughts?

Do they have to sit on top? If not rout down 5 mm or so.

Yes, they have to sit on top. Can't rout into the top surface of the wings. That will compromise the stability of them as timber is weakest in compression.

Maybe raise the neck height with washers so the fingerboard sits higher than the pickups?

I could raise the neck height, but that involves proper shims and the like. I think it's Nordies for the win. :)

If the body is at least 20mm thick I'm fairly certain cutting a 5mm recess rout for the pickups wouldn't do anything and you would get the added bonus of actually being able to tweak your pickup heights properly instead of being stuck having to shim them

On a guitar, I'd agree with you. But with such a long scale and the bass side horn is noticeably flexy. So, I'll go with the Nordies instead. ;)

I must say I'm a little disappointed, Pete - where's your sense of "crazy content" gone?
You can always re-enforce the body with a couple of carbon rods ... .

^ bahahaha! :D

Well that might come into play down the track, but for now, lets see if we can keep it together. ;)
