A completely passive circuit that changes the frequency response of your pickups.

Los Angeles, CA (September 6, 2019) -- It started with a problem that needed a solution; how to achieve greater diversity of guitar tones without switching instruments on stage. The journey led to the discovery of an electrical “back door” whereby the factors that affect pickup response could be altered in a completely natural way. 1960s mode is like taking winds off the pickup, unleashing chime and sparkle, and works great on cleaning up thick humbuckers. 1970s mode warms up bright pickups like single coils, enhancing woody mid-range tone. The Decade effectively triples the sonic options available on any instrument with passive pickups.

Diatonic sequences are powerful tools. Here’s how to use them wisely.



• Understand how to map out the neck in seven positions.
• Learn to combine legato and picking to create long phrases.
• Develop a smooth attack—even at high speeds.

Knowing how to function in different keys is crucial to improvising in any context. One path to fretboard mastery is learning how to move through positions across the neck. Even something as simple as a three-note-per-string major scale can offer loads of options when it’s time to step up and rip. I’m going to outline seven technical sequences, each one focusing on a position of a diatonic major scale. This should provide a fun workout for the fingers and hopefully inspire a few licks of your own.
