FRONT PANEL & CONTROLS:
VOICING SWITCHES: Each channel contains two voicing switches which can further alter the HEARTBREAKERS' sound.
CHANNEL 1: TRIM / FAT: This toggle affects the "HI" mode only. It adds midrange warmth and gain saturation to round out the sound
(FAT), or reduces saturation to leave the natural sound of your guitar more intact (TRIM).

NOTE: Use CAUTION when switching to the BOOST position - turn the MASTER down! The extra gain that is added when
this voicing is chosen increases the volume substantially.
CHANNEL 2: TRIM / FAT: This toggle affects the "HI" mode only. It adds midrange warmth and gain saturation to round out the sound
(FAT), or reduces saturation to leave the natural sound of your guitar more intact (TRIM). BRIGHT / WARM: This toggle affects both
"HI" and "LO" modes. BRIGHT dips the midrange in both modes - creating more sparkle and letting more low end breath through for
clean sounds in the "LO" mode. In the "HI" mode, BRIGHT strips mids to allow the guitars' natural character to come through more
