Wudtone CP (Holy Grail) Tremolo Bridge

Wudtone CP (Constant Pivot) Holy Grail Tremolo Bridge Plate (pat pending, GB1217632.7) is now available in our online shop here. The Wudtone CP VT, same patented design, more vintage correct material, look is also available in our online shop here

Hello there, glad you made it!

Just to let you know, this is lengthy webpage. It aims to:

  • explain the design flaw of Leo Fender’s original vintage bridge plate
  • show you in detail how the Wudtone CP (Constant Pivot ) bridges are designed and manufactured to offer maximum vintage tone with completely stable tuning.
  • share some of our customers delight.

Thank you in advance for reading on.

Leo Fender’s original vintage bridge plate 

A tremolo bridge has always been a key component in the overall sound of an S type guitar. Although there are lots of options along with the current 2 point trem system commonly used,  experience and general consensus would suggest the rather crude, original fender 6 screw vintage bridge, still offers the tone. We share the view of many, that contact with the body of the guitar is what matters for authentic vintage tone and increased sustain. Many guitarists still prefer to use a vintage style bridge because of this, however, there always has been a design flaw with the original, due to the pivot point, which has to slide up and down the screws as it is used. This is turn can affect the tuning stability.

Design flaw in the original plate.

When set up as intended, the original vintage plate operates with two pivot points, A and  B shown on the diagram above. When tilted point B has to slide down the bearing screws and then back up again. Reliefs ( usually countersinks ) are cut underneath. The problem is the force created by string tension is being applied through this sliding pivot point B, which, due to friction, doesn’t always return to the same stable position and correct pitch.

Furthermore, the start of the bevel cut underneath can be a factor affecting feel and stability. If the start of the bevel is in front of point A, the plate will feel very stiff and its movement will be limited. Essentially the plate is trying to dig its way into the body because the length of the diagonal (shown as green arrow) is longer than the vertical space available ( shown as the red arrow). In these circumstances, set up requires the mounting screws to be slackened off a bit and so there becomes even more room for variation in the pivot point B and tuning issues that arise as a consequence. Here is a video showing the issues that arise with set up and operation of an original plate, along with operation of the Wudtone CP (constant pivot) Plate.

As long as you don’t expect to go too far ala Joe Satriani, a carefully set up vintage bridge has few problems for the gentle Shadows kind of trem action.

Having said that many guitarists are hesitant using their vintage trem or simply deck it to avoid set up/tuning problems. Innovative guitarists such as Jeff Beck and Scott Henderson have carved out their own sound, finding ways to express themselves with more trem action in their playing. Why can’t every guitarist have a reliable way to explore a wide envelope of trem action along with a lovely vintage tone?

Well now they can.

The Wudtone CP (Constant Pivot) Technology

At Wudtone we have manufactured a bridge plate that :

  • is easy to set up and works consistently.
  • always returns to pitch.
  • improves vintage tone through even better connection with the body of the guitar.
  • offers smooth feel, with increased sensitivity
  • inspires confidence to explore a wider envelope of up pitch, down pitch, trem action and sounds

The Wudtone CP (constant pivot) design

Here’s the tuning fix (we gave the bearing screws some relief too!)

The design enables the bridge to pivot on the bearing screws at point A. This pivot point remains constant because recesses machined into the top surface of the plate provide relief so that the pivot point A does not need to slide up and down the bearing screws as the trem is used. Having a constant pivot point eliminates the cause of wear and tear, but more importantly completely fixes the tuning problems guitarists experience with the original plates.

An accurate, extended, always on, body connection.
 
The arc between the two green arrows on the underside of the plate (B) also creates a constant connection with the body of the guitar for maximum vintage tone and sustain. We make the bridge in a unique way to maximise contact with the body(see below).
 
Each bridge comes with a stainless steel shim to spread the load on the body, further increase the contact area and provide a low friction metal to metal contact where the bridge slides over the shim at B. This increases sensitivity and improves feel, especially for the light chord shimmer type of use. We have also added some extra mass ( always good for tone) and shaping on the back edge of the plate.  This makes the bridge feel much more comfortable under the palm of your hand when playing. 

Killer Tone

High quality materials + maximum contact = killer tone!
The Wudtone CP Holy Grail plate is made from 3mm, c75, hardened and tempered spring steel. The Wudtone CP VT is made from 2.6mm vintage correct material.
 
 The Holy Grail material is considerably harder (1470 nmm2) than other bridge plates, indeed it is so hard it cannot be bent to form the rear edge as is the case with all other plates we are aware of. 
We machine this super hard material so no forging or heat hardening is required. These processes usually result in a bridge that is slightly convex underneath. The Wudtone CP Holy Grail is perfectly flat underneath to maximise contact.
 
In addition the Wudtone CP bridges don’t have any countersinks underneath. It would be easier and cheaper to countersink but we want as much contact with the body as possible, so instead we machine away the absolute minimum of metal ( see pic left).   This means that the Wudtone CP bridges have 67% of the available footprint in contact with the body. In comparison a stock Fender/Callaham with countersinks manages around 45%. The other bridge you see in the picture (a Wilkinson with elongated countersinks) only 21%. More bridge/body contact = more vintage tone and sustain. 

Max vintage tone, completely stable tuning, confidence, comfort, enjoy!

The Wudtone CP Holy Grail bridge ( pat GB1217632.7) is designed and made in the UK. It is fitted to all our custom guitars and available as an after part upgrade, compatible with existing blocks and saddles with either vintage 2 7/32 dimensions or narrower 2 1/16 MIM and hybrid dimensions in Nickel or Real Gold Plate in our online shop . Combine with the Wudtone 1018 Cold Steel Tone Block  to maximise clarity, sustain, resonance and pure vintage tone!

NEW:

If you want a more vintage correct material / looking tremolo bridge  but with the tuning stability you may expect from a Floyd Rose , The Wudtone CP VT ( same patented design as the Wudtone CP Holy Grail ) is now available in our online shop here

If you have an American Standard / Deluxe Stratocaster and want some real dynamic and vintage tone, we now have an easy fit conversion just for you. More info on the American Standard Conversion here.

TESTIMONIALS
“I have to say that this is the best tremolo i’ve ever had! Great tone and stability!” Marco, Finland 
 
“This bridge plate is clearly a significant positive development in the long history of the Strat trem and I’ll be strongly recommending it to any customer who is interested in improving both the tuning stability and tone on their Strats.” Andy Tatlock – A6 Guitars
 
“Got the bridge plate yesterday and all I can say is WOW! The fit and finish are spectacular, my Callaham trem block fit perfectly as did my Raw Vintage saddles. Best of all, the tone is stellar and it really does work as advertised I’ve had absolutely no tuning instability regardless of how hard it is used; it returns to pitch every time. Thanks for a great product and customer service.” Scott USA
 
“the tuning stability is truly impressive and the guitar rings rings like a bell.” Nico Sabatini, London
 
“I have received the custom pivot bridge plate and the trem block. Well What can i say…I’am Speechless! Tone quality and stability is extraordinary. I don’t want to write a bible about this bridge … this is the best!”  Anura Milan Italy.
“this bridge is a masterpiece ” ebay buyer miri55
 
“I’ve never been able to part with big bucks for a Fender cos I’ve always felt their trem is basically flawed, and I never fancied a two-point trem on a Strat, myself. The Wudtone CP trem really is a nice solution. “ Chris Bird, Bath UK,
 

“I want to express my gratitude for such a wonderful job and say that I am very happy with the result! Sound – above all praise! Sustain and correct tuning. Thank you very much once again. Best regards from Russia!” Albina, Russia
