Late NBD - Cort Curbow, including shaggy dog story about a modding adventure

[neepheid]

As I went down the road to the SE Bass Bash in November I stopped off en route to purchase a bass for the hell of it, a Cort Curbow.  I had always been really intrigued about them, what with their use of man made materials and I always thought they looked pretty neat in some finishes.  I spied one for sale, a sunburst one and figured "what the hell?"

 

 

So, I like how it looks, and I like how it feels to play.  Unfortunately, whilst sounding fine in headphones, it was utter garbage live with the band.  Where are my mids?  This thing is so scooped by default that they're barely noticeable.  I had to crank the mids on the preamp AND crank them on the amp just to be audible, seriously, it just disappeared.

 

Well, I picked it up for a tasty low price so I figured it was worth modding.  I procured a Bartolini Classic Bass soapbar of the appropriate size and shape (MK4CBC) (thanks @Bass Direct) and someone on here sold me a Glockenklang 3 band preamp for a decent price (cheers @Fettsman) and got to work on the mods.

 

Fitting the pickup was a piece of cake, the only thing of note I had to do was accomodate 2 screws on one side instead of one.

 

 

Then I replaced the stupid "slap switch" (which scoops an already inherently scooped bass some more - WHY?) with a much more useful parallel/single/series switch and fed the pickup into that.

 

However, fiting the preamp was another matter.  This body is thin, and to compound the issue, the knobs are sunk into the top.  There was no effing way that Glock was going to fit in there as supplied.  I mean, I was modding it anyway - don't need a blend control on a single pickup bass after all.

 

First problem - the body of the push pull volume control was just too tall, even if the shakeproof washer was eschewed.  So out with the drill and the forstner bit to remove some material from the cavity to sink it down enough so the lid will go down...

 

 

Just made it!  Not a lot of material left, but this luthite stuff seems sturdy so I think it'll be OK.  Then onto the main board, which was way too tall.  So, to scheming.  Thankfully, while the control cavity in the Curbow may be shallow, it is thankfully quite wide.  Lots of dead space above where the bass pot would go...

 

 

So to cut a long story short, I turned it through 90 degrees.  The pot legs wouldn't bend enough while it was mounted, so I had to desolder the pot, bend little 90 degree nubs on the ends of the terminals then resolder it thus:

Did a test fit (the small board attached to the mid pot was able to be bent sufficiently with the pot in situ)...

 

 

Yas, the lid closed.  So I soldered up the rest of the wires...

 

 

Cheeky little single connector block thing for the myriad ground wires I had to connect together...

 

Great success!  It now has mids when the preamp is flat!  I took it to a subsequent band rehearsal and praise be, I was able to hear myself with the preamp set flat.  MIssion accomplished!

 

I hope you enjoyed this shaggy dog story and if you only take away one thing from this, is that it's usually true what they say - where there's a will, there's a way...
