The gain is applied before the tone controls. 13.) Bright - this enhances upper Treble frequencies and helps provide clarity to darker sounding guitars. 14.) Rhythm Volume - this is a volume control for the Rhythm Channel only. 15.) Rhythm Bass - this passive EQ adjusts the low frequency equalization of the amplifier. For tighter low-end response, set the Bass control to lower settings. This is particularly helpful when using the amp at very loud volume levels. 16.) Overdrive - this increases the gain of the second stage of the 12AX7 preamp tube on the Rhythm Channel. 17.) Rhythm Middle - this passive EQ adjusts the midrange equalization of the amplifier. It interacts with the Bass and Treble EQ as described in the Treble EQ section below. For a heavier, more distorted sound, set the Middle lower. For more of a vintage-style, cleaner sound, set the Middle higher. 18.) Rhythm Treble - this passive EQ adjusts the high frequency equalization of the amplifier, but also interacts with the Bass and Middle controls as follows: As Treble is increased, Bass automatically decreases and the Middle slides down in frequency. Conversely, if Treble is decreased, Bass automatically increases and the Middle slides up in frequency. This interaction is typical of classic, passive tone controls and is responsible for the increased effectiveness of such a simple system. 19.) Boost - this is a volume control for the overall amplifier that can be used to boost the volume of solos. The optional HV footswitch can be used to activate this boost. 20.) Effects Level - this control adds the effects section and mixes it into the main signal. Sixteen different effects are available. 21.) Toggle Tap - this momentary switch performs different functions, depending on which effect is selected. Page 6 describes each effect in detail and how to enhance its usefulness with this switch. 22.) Effects Program Select - this switch will select any of sixteen different effects. Page 6 describes each effect in detail. 23.) Effects Active - this switch engages the effects section. The footswitch over-rides this switch when it's plugged into the amp. 24.) Jewel Light ■ this jewel light lets you know that the amplifier is on. 25.) Power Switch - this switch turns on and off the AC power to the amp. 5 HV™ 100THD EFFECTS Effects Level - this control adds the effects section and mixes it into the main signal. Sixteen different effects are available. Effects Program Select - this switch will select any of the sixteen different effects. Effects Active - this switch engages the effects section. The footswitch over-rides this switch when it’s plugged into the amp. Toggle Tap - this switch is a dual function depending on which effect is selected. On “Toggle” effects, this button cycles through alternate variations of the effect. For example, for the Spring Reverb, it cycles through 3 different degrees of brightness. On “Tap” effects, this button selects the rate time at which the effect cycles, by tapping the switch twice. For example, for the Delay setting, it selects the amount of time between delay repeats (If the 2nd tap is beyond the maximum setting, the time will default to the longest available choice).
