1. Guitar input jack
1/4" jack connection for guitar input.
2. Intermediate drive gain control (on side)
Used to fine tune the distortion of rhythm channel-1. Works
in conjunction with DRIVE GAIN switch, DRIVE-1 and
LEVEL-1 controls.
3. Drive-1 control
Used to adjust the amount of input gain & distortion for the
rhythm channel-1.
4. Drive gain switch
Used to set the overall amount of distortion.
LOW = 0dB, MED = +9dB, HIGH = +20dB.
5. Drive-2 control
Used to adjust the amount of input gain & distortion for the
lead channel-2.
6. Mid boost 1 and 2 switches
Separate switches for rhythm channel-1 and lead channel-2.
Used to fatten up the sound for more cut and sustain.
Channel 1 High: Boosts +8dB @ 390Hz
Medium: Boosts +4dB @ 390Hz
Out: Flat, no boost
Channel 2 High: Boosts +12dB @ 390Hz
Medium: Boosts +7dB @ 390Hz
Out: Flat, no boost

7. Filter control
Anti-presence gently reduces
compensate for overly bright amplifiers.
8. Low frequency control
Active 'post-distortion' tone control. Boost or cut ±14.5dB at
100Hz. 12 o'clock position equals zero boost/cut.
9. Top end switch
Shapes the Trimode's overall high frequency response.
BRIGHT: +6dB @ 10kHz, adds sparkle and character.
FLAT: switched out of circuit, no boost or cut.
DARK: -6dB @ 1.8kHz, compensates for bright-sounding
amps.
10. High frequency control
Active 'post-distortion' tone control. Boost or cut ±10dB at
4.3kHz. 12 o'clock position equals zero boost/cut.
11. 12AX7 vacuum tube
The Trimode combines solid-state circuity with a tube
(valve) to create a wide range of distortion from slight over-
drive to bone crunching saturation.
12. Level-1 control
This is used to adjust the overall output level of rhythm
channel-1.
13. Level-2 control
This is used to adjust the overall output level of lead
channel-2.
14. External power supply connection
15VDC (400mA) PSU connection.
15. Effects loop insert jack
1/4" TRS insert jack allows effect pedals to be placed in the
lead channel-2 signal path. (Tip=Send / Ring=Return)
16. Guitar output jack
1/4" jack connects to amplifier's input.
17. True-bypass footswitch with LED indicator
When the Trimode is bypassed, the guitar signal passes
straight through without any effect. The full size
illuminates when in true-bypass mode.
18. Channel toggle footswitch with LED indicators
Toggles between rhythm channel-1 and lead channel-2. Full
size LEDs indicate the active channel.
