Repair on a Tanglewood Stingray copy pickup/control plate

Recommended Posts

I have a Tanglewoord 5 string Stingray copy that has 3 knobs and the input on a control plate:

The first knob does nothing, the second adjusts volume and the third adjusts tone. On opening the plate up I am presented with this:

The red and white wire on the left are soldered together, but not soldered to anything.

I am guessing that this is why the knob doesn't function.

Am I right in thinking that this is a connection from the pickup that controls volume for one of the coils?

Where should I resolder this to on the pot? directly onto it or one of the 3 legs?

 

Any help would be greatly appreciated :)

Most humbucker manufacturers go with the following convention:

red and green - south coil

black and white - north coil

So it looks like the 2 coils have been wired in series (one coil into the next) to give more output.

 

To get the classic ‘ray sound you’d have both coils running in parallel and a 2 band eq. 

If you’ve got a battery box in the bass already then it’s fairly simple to achieve this, but if not then it’s a lot more work.

To use two volume controls (one for each coil) as a passive arrangement follow standard Jazz bass wiring like this:

except that the top pot will have the black wire as the ‘hot’ and the white as ‘ground’ and the middle pot will have red as ‘hot’ and green as ‘ground’ .

you’ll probably notice less output like this, which might be why it’s wired in series in the first place...

Try it, you might like it in parallel!

Think I'll give it a whirl.....I can always resolder it back again :)

 

Cheers for your help with that - first dabble with the electronics and thought I'd been done when i saw the wires disconnected!

You could always replace one of the vol controls with a Single/Series/Parallel switch. That way you get instant switching between the coils and only the 1 Vol control to worry about.

Now that sounds good......is it something a basic person like me could work out? Also any wiring diagrams about for this?

It isn't that difficult. If you feel confident doing the 2 volume wiring, it shouldn't give you much trouble. I probably have some suitable wiring diagrams and will dig them out later.

Magic.......I would really appreciate that :)

It's not that easy to see the details on your pics (could be my eyesight though) but is the solder very messy. If it is, then it could be that someone inexperienced has been in there and caused damaged to the pots, by overheating them when soldering.

@gary mac the last pic shows a red and white wire joined together and not soldered to anything. As suggested it looks like a previous owner has wired the pickup in series configuration. The soldering/wiring in general is pretty bad to say the least.

Here is the wiring for the 3-way switch that someone did to an OLP so exactly what is needed. they only went for Parallel/Series, but it's the same wiring if you use a different switch. You will need to identify which wires go to which coils so a multimeter would be handy. As there are 2 whites and one appears to be grounded on one of the pots, I assume, (maybe not), white is the ground for each coil so substitute White for Black on this diagram.

Green and Red I assume are the pickup hot and black is a common earth.

the switch you need is a DPDT On/On/On

For my passive pretend Ray I got @KiOgonto make me a rotary switch which takes a standard knob. It switches between bridge coil/both in series/both in parallel/neck coil. The control plate looks standard with a volume, tone and rotary switch.

I really like it.

      I'm thinning the herd so this beauty has got to go. It's a stunning bass with a beautiful birdseye/flame maple neck that many 'rays of this era are known for.  This bass also had a fret level and set up by John Shuker last year.
      It comes with a hard case which I believe is original.  It's not one of the Musicman moulded cases, but I've been informed that it's a SKB which were used along with the G&G cases around this era.  It's certainly made for a Stingray as the inner moulding at the headstock has the lower cut-out for the G tuner.
      Manufactured 29th October 1992 Maple neck with Rosewood board Ash body Translucent Teal finish Matt black/white/black plate Metal battery cover 'Off-set' string entry type bridge with mutes 6 bolt neck plate Weight 9lb 13oz Neck width at nut 43mm It's in wonderful condition with only a couple of indentations to the finish on the body (nothing at all that has gone through the finish). 
      I'll try to capture these and add photos later.  EDIT - Photos added showing the worst bruises I can capture.  As you can see, they take nothing away from the bass. I'm just trying to be thorough.
      Collection or meet up only on this at present as I'm short of packaging materials. I am however willing to drive a fair distance for a motorway services rendezvous!
      Not interested in any trades at this time thank you.

      Hi folks, 
      I'm looking to grab a Status in the next few months, so I've decided to sell my pride and joy - My EBMM Stingray Special 4HH. I've owned from new and it has been my most prized possession the entire time. 
      Lovely finish, totally loved. I've just had it setup with new DR highbeams at RamJam in Aberdeen. 

      She's got a 18v 3 band EQ and the usual 5 way pickup selector. 
      And the neck 🥰 The ebony and roasted maple is amazing. It feels amazing. It's comfortably the best neck I've played - so taking a bit of a gamble of the Status! If it doesn't work out... I'll defo be back to the EBMM Special! 
      Comes with EBMM hard case and Schaller strap locks. If anyone wants more photos, just let me know. 
      This is the serial checker from EB. 

      Serial #F82390
      Manufactured January 3rd, 2019
      Build Code 108-CP-50-01-CS-BM
      Model StingRay Special HH
      Color Charcoal Sparkle
      Neck Roasted Maple Neck Ebony Fretboard
      Pickguard Black Pickguard 2018
      Hardware Matte Black Hardware
      According to the EBMM website, the colour is discontinued and a few places I saw online aren't getting stock for a few months. 
      I'm based in Aberdeen, but happy to look at shipping. 😉

      I'm selling my Poller 3/4 (standard) size double bass. Really great bass for students or jazz/rockabilly. I gigged it professionally for several years before upgrading.
      It's made in Romania in the early 90s. It has been my backup bass for the last few years but I can’t justify keeping two at the moment.
      Makes a great bass for a student or an electric bass player taking up upright - I’ve gigged it and and it is very light so great for carrying around to gigs etc. I’ll include a soft case and I can probably find a spare double bass stand if you would like one too.
      Price drop to £795 and open to sensible offers and happy to chuck in the Realist for a little extra.
      I'm currently located in Surrey/Kingston so delivery/trial around the south east is possible. You are welcome to come for a socially distanced play in the garden but serious buyers only please. Any questions let me know!
      Many thanks
      Dan

      The instrument is from 1998 and is in excellent condition for an instrument of this age. The frets are excellent, the electronics work great, the neck and the truss rod are perfect. The fingerboard is of a very nice and compact rosewood and the back of the neck is painted in a faded satin color, for a better smoothness. Matched headstock. There are a couple of marks and the paint is a little cracked in one place, as shown in the photo. Nothing to worry about or compromise the instrument. Original hard case included
