1.0dB INPUT: The signal output from an instrument (active or pas- sive – typically passive) or a line level signal may be connected here by means of a shielded instrument cable. The signal at this jack is sent into the preamp at full amplitude.
2.
3.MUTE: This switch, when depressed, mutes all outputs except the Tuner Out (28). This is excellent for tuning your bass with an elec- tronic tuner without having to adjust any levels or turn down your stage volume.
4.COMBINE: This switch, when depressed, allows the clean chan- nel to remain active when the overdrive channel is selected, combin- ing the two channels to create a
CLEAN CHANNEL:
5.VOLUME: This control adjusts the output level for the clean chan- nel and the input to the Octave circuit (16). Adjust this control no high- er than that which causes the Peak/Mute LED (6) to flash on strong signal peaks.
6.PEAK/MUTE LED: This LED flashes when the signal level in the preamp approaches clipping. When the Mute switch (3) is depressed, this LED remains illuminated until the Mute is turned off.
7.STYLE: This
– experiment with the Style and other EQ controls for the results which suit you best.
POSITION 1: Fully “scooped” mids (mid cut)
POSITION 2: Traditional passive tone setting
POSITION 3: Basically flat
POSITION 4: Boosted high end
POSITION 5: Basically flat with low end
8.BASS: This is the primary low frequency control which has a range of 22dB @ 50Hz.
9.ULTRA MID: This is the primary midrange control which has a range of 13dB @ 250Hz.
10.TREBLE: This is the primary high frequency control which has a range of 22dB @ 8kHz.
11.CHANNEL SELECT: This switch selects the clean channel in the out position and the overdrive channel when depressed.
OVERDRIVE CHANNEL:
12.OD BOOST: This switch, when depressed, adds gain and tone shaping to the overdrive channel signal for heavy overdrive.
13.GAIN: This control sets the level of the signal entering the pre- amp stage.
14.STYLE: This
POSITION 1: Mid cut – for clean to
POSITION 2: Slight mid cut
POSITION 3: Basically flat
POSITION 4: High end
POSITION 5: Large mid peak tailored for heavily overdriven sound combined with the clean channel
15.VOLUME: This control adjusts the output level for the overdrive channel.
16.OCTAVE VOLUME: This control adjusts the output level for an added signal which is one octave lower than the instrument’s original signal. This signal is dependent on the clean channel’s Volume con- trol (5) and can be switched by the Octave footswitch (31). The effec- tiveness of this signal depends on playing style, pickup selection, and neck position.
17.FX BLEND: This control varies the mix between the direct (dry) signal and the effects (wet) when the effects loop (26,27) is used. Full counterclockwise results in all direct signal (no effect) and full clock- wise gives all effect and no direct signal. The clockwise position is equivalent to a series effects loop and should be used with such devices as limiters and equalizers.
18.MASTER: This control sets the overall output level of the amplifier.
19.OD/CLEAN LEDS: The red LED (“OD,” upper) illuminates when the overdrive channel is selected, while the green LED (“CLEAN,” lower) illuminates when the clean channel is selected.
