Building a Wal....ish

Recommended Posts

Has anyone compared the Turner pickups with the Herricks ? I visted the Herrick website https://www.herrickpickups.com/ and there is an interest blurb on what he does different:

 

Practically ALL our Multi-coil pickups are built with an integral full Soft Steel or Wrought Iron chassis. This chassis ensures that the tone is true to the genuine, Multi-coil sound . The reason for using a chassis is not just so that the pole pieces are height adjustable to handle just about any radiused finger board, but more importantly to Ensure that the Tone is Un-Coloured & Un-affected by the magnets used in construction .

The multi coils in Herrick Pickups are driven by the Magneto-Motive force passing through The Steel chassis & Pole pieces rather than the simple 1-magnet-per-coil set up used by other multi-coil pickup makers. 

A magnetised chassis makes the Tone experienced by the player as Transparent as possible to enhance the Natural tone of the actual woods used in your specific Instrument.

This is an important factor when choosing a multi-coil pickup system in both a passive circuit or with an active pre-amp as the Tone focuses on the woods used in construction, which makes every Instrument's tone Unique.

It's true that our multi-coil pickups are a little more expensive than other brands that lack a proper Steel or Wrought Iron chassis.

But when the benefits of the superior build are considered, Herrick multi-coils represent unbeatable value for money & a sound Investment for our customers.

 

Sure sounds interesting..

I definitely haven’t. Interested to hear others experiences. I’m not exactly sure what all of what was posted means either, but I assume that someone with better knowledge can translate.

is that that the pole pieces are steel and the magnets are at the bottom (like a Dimarzio P pickup) as opposed to where the pole pieces are the magnet (fender style) ?

 

 

That's probably what they're referring to...  steel pole pieces and steel "keepers" (chassis?) with magnets charging those, rather than something like Alnico rod magnets as poles.

Like Wal did/does with their pickups, as Pete mentioned early on in this thread: 


It's also how I do mine, with the English voicing versions having the thicker mild steel keepers and ceramic magnets that charge the and the pole screws (Original voicing construction is the same, but with shorter/thinner keepers and magnets, different wind count and wire gauge):

These look like the Bartolini HI-A pickups which had an individual coil for each string.

Well NFP Special preamp should be here in a few days, gonna start making a new scratch plate for my p bass to accommodate the Turner multicoil and preamp. Then it’s just a case of sitting and bracing myself for the teabagging when the pickups arrive in the UK and I get the customs bill 😬

An interesting thing about the Herrick pickups is something a bit odd. Now, Martin advertises them as obviously needing routing for the depth. That's fine of course. What he didn't say was that the ears where the screws go in aren't straight and slope outwards towards the bottom. So, I had to get a tech to file half the casing back by 3mm up to halfway up the pickup.

 

Now when I said this, Martin told me he'd had feedback about this issue with standard MM cavities which I thought was peculiar he didn't say that or list it on his website.

 

Alas, I've not yet got the neck for the bitsa thr pickups are in, so I can't tell anyone how it compares to a Wal.

I haven’t seen any Stingray pickups or cavities with a slope/angle, and I’ve owned a few Stingrays…

It wasn't the pickups themselves. It was the ears where you'd put the screws through the pickups into the body. What it meant was that even discounting the difference in depth, they didn't fit without being filed down. I just thought it was weird that it wasn't on their website as there was no way they'd properly fit a Stingray route without some filing.

It’s happening 🥲

@funkle any thoughts around adapting the P-bass and placement? I was thinking when I make the new pick guard I’d make it slightly lower so that the pickups can sit closer to the bridge.

 

The electronics cavity might need to grow a slither to accommodate the extra control too!

Please excuse the crudeness of the mockup, the size of the pickups is correct but missing the ears/lugs/screw thingys.

Hi gues! Sorry for my English.  I was very interested in the information from this thread, and I tried to make my own version of the wal amplifier.  I had to change the input stages to be able to adjust the original frequencies of the pickup.  I made a test recording yesterday on jazz bass

P. S. : Don't judge my performance too harshly, I tried to record this quickly, I haven't played tool band covers before

You built a preamp this preamp of your own design ? It sounds good to me and the play is nice.

Вы построили предусилитель собственной разработки? Мне это кажется хорошим, и пьеса хороша.

You're right my friend. I studied the data in this thread and designed an equivalent circuit for the wal pickups. I corrected for deviations, and designed the amplifier's input stages so that the connected pickups were corrected for the frequencies of the original pickups.

Heck, the Turner multicoils just arrived today and they’re hefty! Here’s a DiMarzio Model P for reference.

Build quality is fantastic on these!

have fun with the router you're buying tomorrow! :D

Haha well fortunately my dad was a luthier and still got all the gear and a small workshop available for use 🙌


Gonna be a fair bit of work, gotta make the router templates, router the new cavity for the bridge, extend the P cavity for the neck and then make the scratch plate.

 

Got a long list of other bits to sort like fixing a few dings, sorting a loose screw on the neck and strap lock where it’s loose. Also wanna take some of the gloss out of the finish.

 

May be a few evenings before I get to play it 🥲

Hello, friends!  I did a short review of my Wal based preamp.  Sorry for my terrible slap, it doesn't work for me.  The preamplifier has 2 input stage modes.  Here is the first version, the second version could not be recorded.  The second version has more presence.  Thank you for watching!

Just finished routing the pick guard and some finishing touches like countersinking the screws etc. Was just about to connect it up and realised all my flathead screwdrivers i need to connect the pickups and preamp have gone missing 🥲

Very happy with how it’s turning out, ended up spacing the pickups a little further than initially intended largely down to cosmetics and symmetry.

Hi all!  I recently posted examples of the sound of a wal clone preamp with cheap Chinese pickups.  I decided to go ahead and wound the pickups to approximate the specifications of the original wal pickups.  I made a series of calculations and determined the characteristics of the original sensors, after which I made low-impedance coils of 1k6 and 1k9 resistance.  Since the resonant peak of the original sounds determines the maximum only for the pick attack function, I decided to correct the peak on the spot.  The pick attack frequency is in the range of 6300-6700Hz, so I simply adjusted the resonant peak of my sounds after taking measurements.  I'm planning to make full-length multi coil pickups soon.  As an example of the sound, I attach a small cover.  I apologize for my English, and for the cover - this is the only track that was played nearby, which I decided to play :) there are two modes in the first and second verses, respectively

Hi all!  I'm probably getting pretty fed up with my posts, but today I finally finished building the pick attack, and I want to show you what happened.  I apologize for the poor performance, I am not a tool player, the sound is not processed in any way, there is no vst.  I am ready to answer any questions regarding the wal amplifier.
