Frequently Asked Questions
The AH-4 will generally have a higher output than a JB, offering more drive and sustain, but the JB retains a more nuanced dynamic response.
Yes, the 50mm spacing is standard for many guitars, but you'll need to verify your guitar's pickup cavity dimensions and routing to ensure proper fit. It'll be a modern, high-output addition to either guitar.
3.4 kHz is a moderate resonance frequency, contributing to the pickup's mid-forward character and helping it cut through a mix, but it won't be overly bright.
