JHS Angry Charlie Settings Guide
The JHS Angry Charlie is a Marshall-in-a-box overdrive/distortion based on the JCM800 2203 preamp topology. Four controls (Volume, Gain, Bass, Treble) capture the essential JCM800 voicing — the tight, aggressive midrange crunch and scoopable low-end that defines classic rock and hard rock guitar. It works best into a clean amp, letting the pedal supply the British crunch rather than the amp.
The best JHS Angry Charlie settings start with: Volume at 5/10, Gain at 5/10, Bass at 5/10, Treble at 6/10. Adjust from there based on your amp, guitar, and room volume. For Classic Rock: Volume 5/10, Gain 5/10, Bass 5/10, Treble 6/10.

Settings by Genre
Gain 5, Treble 6 — the JCM800 crunch zone. The Angry Charlie reproduces the mid-forward Marshall character. Keep a clean amp behind it (Fender, Roland JC-120) and let the pedal do all the gain work. Into a naturally breaking-up amp, back off the Gain to 3.
Gain 7 provides full hard rock distortion. The Angry Charlie at this level captures the 1980s hard rock rhythm character — aggressive, mid-forward, with tight bass.
Lower Gain for a warm, lightly overdriven British crunch — responsive to pick attack. Higher Volume increases presence in the mix. Use the guitar volume knob to clean up from this setting.
Maximum Gain with Bass pulled back and Treble pushed produces a tight, aggressive high-gain tone in the JCM800 family, though a purpose-built high-gain amp will still out-saturate this pedal at its absolute ceiling.
Minimum Gain with Volume above unity works as a bright, mid-forward clean boost, pushing a clean amp toward its own natural breakup rather than adding the pedal own distortion character.
Tips & Common Mistakes
- The Angry Charlie is a preamp-level simulation — into a clean amp it behaves like having the JCM800 preamp in a pedal. The character is most convincing into a genuinely clean amp (Fender clean, Roland JC-120) rather than an already slightly-dirty amp.
- Stack a Tube Screamer before the Angry Charlie (TS Drive 0, Level high) for compressed, singing lead tone. The TS tightens the low end and boosts the input, pushing the Angry Charlie into a more saturated, harmonically rich zone.
- Bass and Treble interact with Gain more noticeably on this circuit than on a simpler overdrive — small EQ changes at high Gain settings produce larger audible shifts than the same changes at low Gain.
- Because this pedal models a specific preamp stage rather than a full amp, pairing it with a cabinet-simulation pedal or plugin for direct recording gets closer to a convincing full-amp sound than running it into an interface with no cab sim at all.
- For rhythm parts that need to sit under a lead boost, set the base Gain slightly lower than instinct suggests and rely on a clean boost or a second overdrive stacked in front for the lead lift, rather than maxing Gain for rhythm alone.
