Iris Amp Settings Suggestions
- Bass: 5

- Master: 6
- Cut: 4
- Gain: 6
Note: The Matchless DC-30 amp typically features controls such as Bass, Treble, Cut, Volume, Master, and Gain. Mids are not always present on all Matchless models, so the midrange may need to be shaped using external EQ or pedals.

Set your amp's output first (master), channel volume, then your EQ.
Guitar-Related Tone Tips
1. Volume
- Set the guitar’s volume to about 75-90% for a full yet controlled output.
- Use a volume pedal or amp volume adjustments for dynamic live performance blending.
2. Tone
- Keep the tone control slightly rolled off—around 70%—to reduce excessive brightness.
- Aim for a warm, rounded sound that retains clarity in arpeggiated chords.
- Use amp EQ settings to further sculpt mids and highs for a smooth presence.
3. Pickup Selector
- Use the middle pickup position if available to blend neck and bridge pickups.
- If using a two-pickup setup, switch to the neck pickup for warmth in rhythm passages.
- The goal is a balanced tone that captures both warmth and sparkle of the 12-string style.
4. Humbucker or Single Coil Preferred?
- Use humbuckers for a fuller sound and to avoid excessive noise or buzz with jangly chords.
- Mini-humbuckers or Filter’Tron-style pickups provide excellent articulation and smooth overdrive if needed.
5. Ideal Guitar Type
- Electric semi-hollow 12-string guitar most closely matches the tone of “Iris.”
- Models like the Gibson ES-335 12-String or Rickenbacker 360/12 are ideal.
- Semi-hollow body adds resonance and warmth while 12-string configuration gives the iconic shimmer and depth.
