Additional Guitar and Amp Tone Tips
1. Volume
- Set your guitar volume knob to 10 for full output and aggressive tone.
- Ensure your amp’s master volume matches the desired stage or practice level, but keep preamp gain fairly high.
2. Tone
- Guitar tone knob should be set to 10 for clarity and brightness.
- Use amp EQ with the following ballpark settings: Bass at 5-6, Mid at 3-5, Treble at 6-7.
- Add tight compression and high-gain amp tone with some mid-scoop for a punchy metal feel.
- Use a precision noise gate and some light reverb for ambience without muddying the tone.
3. Pickup Selector
- Use the bridge pickup for a tighter, more aggressive tone suitable for heavy riffing.
- For lead parts or solos with sustain, switch to bridge or combined bridge + neck setting if available.
4. Humbucker or Single Coil Preferred?
- Humbuckers are preferred for the high-output, thick, and aggressive tone found in “Judith.”
- Active humbuckers like EMG 81/85 or passive high-output options like Seymour Duncan JB are ideal choices.
5. Ideal guitar type which is a ESP LTD
- ESP LTD models with aggressive body shapes like the EC or MH series are great choices.
- Look for models with set-neck or neck-thru construction for sustain and resonance.
- Prefer guitars equipped with high-output humbuckers (EMG 81/85 or Seymour Duncan Distortion). Active pickups are ideal.
- Solid mahogany body with maple top for warmth and harmonic content.
- 6-string with a fixed bridge or string-through for tuning stability; use drop D tuning to match the “Judith” tone.
Gear Recommended for Covering Judith
- Gibson Les Paul Custom: Used by Billy Howerdel; offers thick, sustaining tone ideal for heavy riffing in “Judith”
- Diezel VH4 Amp: Howerdel’s main amp during the Mer de Noms era; known for articulate high-gain tones
- Mesa/Boogie Dual Rectifier: A secondary amp Howerdel used live; great for aggressive, tight distortion
- Boss DD-5 Digital Delay: Used for ambient and spacious lead parts
- Line 6 DL4 Delay Modeler: Employed by Howerdel for looping and experimental textures
- Prescription Electronics Overdriver: Adds smooth, vintage-style drive layered over amp distortion
- Ernie Ball VP Jr Volume Pedal: Helps with dynamics and delay swell techniques
- Dunlop Cry Baby 535Q Wah: Adjustable Q control gives tonal flexibility for expressive leads
- EMG 85/81 Pickups (Optional): Active pickups used on some guitars for tight, aggressive sound
Expanded Suggestions and Best Practices
- Use a tight, focused distortion tone with high midrange presence and moderate bass.
- Scoop low mids slightly to match Adam Jones’ tone signature.
- Use a bridge humbucker pickup for aggressive attack and clarity.
- Apply light compression to tighten palm-muted riffs.
- Set gain to medium-high; avoid over-saturation for clarity in rhythmic passages.
- Utilize a noise gate to control feedback and sustain between staccato riffs.
- Keep modulation effects minimal or bypassed to maintain raw tone.
- Use EQ to emphasize 1kHz to 2kHz range for defined lead lines.
- Reverb should be minimal or off to preserve a tight, dry mix.
- Match tempo and syncopation precisely; timing is critical in riff execution.
