1995 American Standard Strat

In walks a chap with a beaten-up case and a conundrum. Always a good sign of an exciting project. This was a case of someone having a guitar they adore, have owned for years but as the musical tastes and styles evolved, the guitar couldn’t keep up. This is a frequent story. And as usual, single coil pick-ups can’t achieve the sonic brief of humbuckers. I lent him a couple of humbucker-equipped guitars to take away to explore and drew up a list of options for his beloved US Strat. A second meeting soon followed with his own DAW and set-up, and a line of guitars with different styles of pick-up to play through ready for him to explore the realities of the options. Many types and designs of single coil, P-90 and humbuckers fed his tracks and the nearest we could get to what he needed was a pair of VH-7 Fernandes dual blade single coil sized humbuckers. High powered ceramic pick-ups such as the VH-7 are ideal for the heavy distortion sounds but lose their advantage with softer clean tones, where the original Fender AmStd coils delivered that perfectly. What this chap really wanted was everything and all in between!

A few conversations with some of the industry’s finest brains later and we draw up a plan that takes a few risks, but we think will deliver.

A set of custom wound AlNiCo 8 blade single coil sized humbuckers was ordered from Harry Häussel – Germany’s finest pick-up winder. I will set them low in the plate and find that pick-up height that gets the “sweetness”, yet has all the power and definition expected from a hot ceramic.

The pick-ups would be 4-conductor so he can obtain true single coil tones from all 3 – this guy uses all 5 positions on the selector but left the TBX control alone, keeping it just on the bright side. The upper tone knob had nearly seized up through lack of use. This gave me ample room to develop a wiring and control philosophy to really unlock the available tones from these pick-ups.

A criticism of all the single coil guitars in the DAW experiment was the buzz – especially with saturated signal paths. A criticism of master coil split functions is the usual volume drop and essentially changing the whole guitar from one set of tones to another. A limitation of the traditional coil split function is a coil removed completely from the palette. A criticism of traditional designs to overcome all of this is a guitar full of switches and knobs – usually hard to identify in the dark, and a messy looking guitar. My control philosophy would therefore attempt to unlock as much of the tonal palette from 3 humbuckers as possible without changing the fundamental look of the guitar.

The neck and bridge humbuckers are controlled by the lower tone control. At zero setting, the pick-up is a single coil with 15% of the adjoining coil in the circuit. Turning the knob increases the percentage of the adjoining coil until a true humbucker is reached at 10. This is a push-pull pot and the position of this determines which coil is permanently in the circuit. Pulling up the knob selects the coil nearest the bridge as the permanent coil; pushing it down swaps this to the adjoining coil. This does a decent job of migrating the humbucker tone towards a Tele or a Strat tone – not exactly emulating a Tele obviously, but the brightness of that coil gives it an extra treble edge.

The middle humbucker is split in half by an S-1 switch on the master volume, and the upper tone knob is a master tone control with a Centralab PIO 0.022μf capacitor.

The range of tones is vast, while still behaving, feeling and playing like a Stratocaster. As with all upgrades that take a departure from the original control philosophy, this takes a few hours to get used to, and probably a few months to discover what the guitar can deliver for you, but this achieved and exceeded the initial brief.

A few raised eyebrows expected with the AlNiCo8 spec, but set them at the right height from the strings and you will be rewarded by the best of all worlds. This particular specification suited this project – but the fundamental design would be applicable to many others with different types of pick-ups and budgets. This was not a cheap project, but when the inspiration and thinking is taken to this level, this investment has saved the customer money in that he doesn’t need to buy another guitar.
