DRIVE control: Used to adjust overall amount of input gain &
distortion. For even more drive, use the GAIN switch.
GAIN switch: Used to boost the gain at preamp input. LOW = 0dB
MED = +9dB HIGH = +20dB.[+] Hint: Start with GAIN in low position
and DRIVE at 9:00 o’clock and LEVEL at 3:00. Then add DRIVE.
FILTER control: Used to balance the high frequency ratio between
the amplifier and the ToneBone - Hint: start adjustments at the
full clockwise position and work backwards.
MID BOOST switch: Gives you +7dB & +12dB boost @ 360Hz.
Allows guitar to cut through the mix; especially useful for soloing.
LOW control: Active ‘post-distortion’ tone control. Boost or cut
±14.5 dB @ 100 Hz from 12 o’clock position.
TOP END switch: BRIGHT = +6dB @ 10KHz FLAT is the
Recommended position when the amp’s bright switch is on. DARK: -
6dB @ 3.3KHz, normally used with super bright inputs.
HIGH control: Active ‘post-distortion’ tone control. Boost or cut
±10dB @ 4.3KHz from 12 o’clock position.
LEVEL control: This is used to adjust the output level without
altering any of the tonal characteristics.
Foot-switch: True-Bypass type; i.e.: when the Tonebone is off,
the signal passes straight through without any effect. An on/off
status indicator LED is provided.
