JHS Pedals Charlie Brown V4 Overdrive

The JHS Charlie Brown V4 is a Marshall JTM45–inspired overdrive designed to replicate the thick, chewy, vintage British rock tone. It includes a 3-band Marshall-style tone stack that lets you dial in classic sounds—from ’60s-style crunch to rich, liquid rock—with just the Drive knob and your guitar’s volume control.

Takeaway
