INSPIRED BY OVER A DECADE OF ELECTRIC GUITAR STRING RESEARCH

HT pickup technology is a new material-based innovation made possible by principles and insights learned from the research and development of Cobalt and M-Steel string technology.

HT Single Coil Pickups

The Luke 4 HT single coil pickups can achieve an ultra-high-output, powerful, low-end response while retaining a clean, clear tone at lower volume levels. This set of pickups has been crafted for a complimentary tonal offering across all five switch positions.
HT Humbucking Bridge Pickup

The Luke 4 HT bridge pickup outperforms regular spec pickups with ultra-high output, more dynamic range, and excellent touch sensitivity. The pickup garners a powerful low-end response while retaining a distinctively clean, clear tone and definition at lower volume levels.

Luke 4 – Push Push Boost Circuit

Push Push Boost Circuit

A push-push volume knob activates the Luke 4 HT preamp boost and is factory set to 12db. Via a trim pot inside the control cavity, the preamp can be adjusted up to 20db if needed for heavy rhythm parts or high-octane soloing whenever the user chooses.

Luke 4 – Designed to Perfection

Designed to Perfection

The Luke 4's double-cutaway design features a balanced, resonant Okoume body for extreme playing comfort. The premium roasted maple neck is beautifully figured and features a soft "V" profile that comfortably fits in the palm of your hand.

Luke 4 – Schaller Locking Tuners

Schaller Locking Tuners
