tion with the Lead Master to adjust the amount of distortion and volume for the channel. For cleaner sounds, this control would be set to lower settings and the Master set higher...for slight breakup, the controls would be set in their middle ranges...for heavier distortion, set the Lead Volume higher and the Master lower. Pulling the Pull Bright will increase the high frequencies of the signal, while also reducing low frequencies for a chunkier, tighter attack. This function is very useful for fine-tuning the amp’s tone and feel for different guitars.
9)Lead Master—The Lead Master sets the overall volume of the Lead chan- nel, and can be used to balance the volumes between it and the Rhythm channel. The interactions between Volume and Master are described in detail in the previous section entitled 8) Lead Volume/Pull Bright.
10)Bass EQ—This passive EQ adjusts the low frequency equalization of the amplifier. It interacts with the Middle and Treble as described in the 12) Treble EQ section. For a tighter low end, use the Bass EQ set to lower settings. This is particularly helpful when using the amp at very loud settings. This EQ works for both Rhythm and Lead channels.
11)Middle EQ—This passive EQ adjusts the midrange equalization of the amplifier. It interacts with the Bass and Treble EQ as described in the 12) Treble EQ section. For a heavier, more distorted sound, set the Middle lower. For more of a vintage-style, cleaner sound, set the Middle higher. This EQ works for both Rhythm and Lead channels.
12)Treble EQ—This passive EQ adjusts the high frequency equalization of the amplifier, but also interacts with the Bass and Middle controls as follows: As the Treble is increased, the Bass automatically decreases and the Middle slides down in frequency. Conversely, if the Treble is decreased, the Bass automatically increases and the Middle slides up in frequency. This interac- tion is typical of vintage-style passive EQ, and is responsible for the increased effectivity of such a simple system.
13)Reverb Intensity—The Reverb Intensity controls the amount of rever- beration effect in the amplifier. This effect is created by an authentic spring reverb pan, and sounds essentially like playing the amp in a large room. The Reverb can be defeated with the footswitch, or by turning the Intensity control fully counter-clockwise.
14)Reverb Tone—A traditional Kustom feature, the Reverb Tone allows the user to fine-tune the sound of the reverb effect. Turning this Tone fully clock- wise yields a very bright reverb effect with emphasized “spring.” By turning the Reverb Tone down, a warmer, less-springy sounding reverb effect results. The warmer reverb tone allows for more reverb intensity without dominating the sound.
15)Jeweled Pilot Light—Indicates that the amplifier’s power switch is in the On position.
16)On/Off Power—Provides AC power to the amplifier when in the “On” position—switched to the left.
17)Standby—This allows the amplifier to be powered up, but with the tubes in a non-operational mode. The Standby can be used instead of the power switch between performance sets, since it allows the amp to “shut down” while keeping the tubes warm and ready to go. It’s also best to power the amp up with this switch set to the right/off position until the tubes have had a few minutes to warm up, although modern tubes are more tolerant of this.
