Tonerider AC4 Alnico IV Humbucker PAF Pickup


In Stock: Available



Not all guitars are created equal. Some just don't have the tightness and clarity that you expect, especially with lower output pickps.

The Tonerider AC4 is a matched humbucker set that is pick sensitive, rich in harmonics and with a tight bass.

The Alnico 4 Classics Set began life as a rumour. We'd heard for years that some boutique makers were sourcing Alnico 4, and player response was great. At least one famous pickup maker claimed they couldn't tell the difference between Alnico 4 and Alnico 2.

To develop the AC4, we used a great Gibson Historic Les Paul that had the perfect maple and mahogany combination that makes specially voiced Les Paul-style guitars.

We made a few of these pickups back in 2007 and they quickly became favourites, and launched them into our standard range in 2008. The Alnico II Classic set in Nickel is currently our bestselling humbucker.

    Tonerider AC4 Alnico IV Humbucker PAF Pickup set

    Posted by Trevor Cooke on 21st Feb 2019

    I got these pickups to replace the Epiphone Alnico Classic Pickups in my Lucille. My feeling was both pickups were a bit bland, lacked definition and needed ‘opening up’ somewhat. The Tonerider AC4’s arrived promptly and have a good quality feel to them. On fitting them and setting the guitar up the same as before, they needed a bit of height adjustment to both before getting the balance right. Now playing the Lucille through the same amp settings as before is a revelation – there’s a noticeable improvement in dynamic range, and wider breadth of tones from both pickups. Well pleased with the result!
