The Wolfram Martin Simpson Signature Slide is engineered without compromise, to deliver unsurpassed tone, volume, sustain and feel.

Tone - our Martin Simpson Signature Slide sounds beautiful. With a rock-solid fundamental, great clarity and rich overtones, undesired buzzes and 'pings' are completely absent. Bass response from the wound strings is astounding, and sustain, volume and dynamics are unsurpassed. The extreme mass, hardness and mirror finish mean the slide saps virtually no energy from the strings through friction or vibration; it is retained in the string where your guitar can convert all that energy into tone. Many of our customers tell us that their guitar sounds like a whole new and better instrument.

"There is nothing about this slide that I was not totally knocked out by. It just glided over the strings like silk and the tone, volume and clarity of the notes produced was just incredible."
 
Michael Messer


Design - with its straight outer and tapered inner walls, the CAD-designed Wolfram Martin Simpson Signature Slide is thicker and heavier at one end. This balances the slide, throwing the mass towards the fingertip for a great fit and feel, and more precise control. The precisely radiused cylinder ends combine function and aesthetics. As well as enhancing the beauty and feel of the slide, they make sensitive interaction with the strings possible for techniques such as hammer-ons and pull-offs.

 

Material - our slides are crafted from an advanced high-density nickel tungsten carbide metal matrix composite, weighing nearly 30% more than lead and about twice as much as steel. This enables us to pack extreme mass, with all its tonal advantages, into a compact, comfortable and agile slide. Weighing over 190 grams, this is one of the heaviest guitar slides in the world. It is also one of the most comfortable.

Nickel tungsten carbide is so dense that a deviation of just one quarter of a millimeter could change the weight by over 10 grams. To accurately realise our balanced design and maintain consistency, we manufacture our slides to a minute tolerance of five hundredths of a millimeter.

 

Finish - our slides are lovingly polished by hand to a perfect mirror finish with diamond paste. The flawless finish enables the slide to glide effortlessly over the strings - particularly the wound strings - with virtually no friction or string noise. Nickel tungsten carbide is extremely hard - comparable to sapphire and almost as hard as diamond. It will not mark or scratch with normal use. Looked after, a Wolfram slide will retain its beautiful finish and look as good as new for many, many years.

Martin Simpson chooses Wolfram Slides

Martin Simpson is widely acknowledged as one of the finest acoustic and slide players in the world. Along with his superb technique and the subtlety and depth of his playing, his slide is a key part of the astonishing tone he achieves. Martin has used a custom-made tungsten carbide slide for many years. We took this slide as our starting point, and made it our mission to improve and fine-tune every aspect of it: the tungsten carbide composition, the dimensions and gradient of taper, the radiusing and the quality of finish. Our aim was simple: to create the ultimate guitar slide.

When we showed Martin our very first production prototype in January 2013, he declared it the finest slide he had encountered and endorsed our product - he now uses his Wolfram slide exclusively.

We have worked together to bring the Wolfram Martin Simpson Signature Slides to market in limited numbers, so that it can be enjoyed by serious slide guitarists around the world.

"These are literally the finest slides available, anywhere... If you're a slide player, this could change your life."
 
Martin Simpson
