The Evocations hope to ‘evoke’ the sound of a 50s Gibson Les Paul, aiming to replicate the open and unbalanced sound of early Gibson PAF pickups – using traditional 42AWG wire to achieve a vintage output without underwinding, attaining a vintage correct tone that still pushes even modern tube amplifiers.
 
To properly encapsulate the full range of PAF tones, the Evocation is available in two variants: the Evocation I, and the Evocation II.
The Evocation I is modelled after the driving, raunchy PAF tone that made original Les Pauls icons of rock and roll, with plenty of punch and guts, but incredible levels of tonal intricacy. This is the original Alchemy Evocation pickup set, and has been described by a customer with an LP style guitar as having "so much more tone" and "making my guitar sound the way it always should have".
The Evocation II has more of a focus on clarity, with a more airy and lyrical quality, and has been styled after slightly lower output PAFs that would turn up from time to time in Les Pauls, as well as humbuckers found in late 50s semi-hollow guitars such as the original ES-335. The Evocation II neck pickup has been described by a customer who has played a '59 Les Paul as "the closest I've ever heard to the original burstbucker sound".
 
The Evocation I bridge uses an AlNiCo IV magnet for organic, vintage highs, with solid mids and relatively tight bass response. The neck is powered by an AlNiCo II magnet, emphasising the natural warmth of the position, producing a gorgeous and complex middle position sound, and making the set overall as versatile as PAF pickups, capable of bassy, warm cleans, clear, soaring highs, and driven, crunchy classic rock tones.
 
The Evocation II bridge is powered by an AlNiCo II bar magnet with a lower wind to achieve a more subdued and warmer overall tonal response, with deep, intricate mids and rounded trebles. The calibrated neck pickup is AlNiCo III powered, and gives a comparitively open, airy and transprent sound to the neck position, allowing the tonal complexities of the instrument to shine through unimpeded. The balance of a softer bridge tone and more transparent neck gives the Evocation II an incredibly rich middle sound, and the overall tonal quality of the three postions makes them perfect for blues and softer classic rock playing, with unparalleled cleans and soulful lead tones.
 
All Evocation models are made using the classic slower scatterwind and unbalanced coils associated with the original PAFs.
