5
8) MASTER (CH2)
This control is the master feed from the end of the preamp channel to the tube power stage. It allows you to obtain a wide range of sounds/
colours in relation to the gain setting—for example, very low gain sounds at high volumes or high gain sounds at low volumes.
9) BASS
This knob controls the amount of low frequencies in your sound. When you’re starting to explore sounds on the amp, avoid boosting the lows
too much as this can reduce your attack and muddy your sound—especially as you turn up your gain.
10) MIDDLE
The Middle control regulates the midrange frequencies and is an important part of your tone shaping. The frequency range it boosts and cuts
has a big effect on the character of your sound. For a more scoopy tone, lower the mids. Turn the knob up for more focused attack and better
pitch definition.
11) HIGH
The High knob controls how much of the preamp’s high frequencies are blended into the signal. It can produce unwanted noise (hiss) or pickup
feedback if really cranked, so it’s best to avoid extreme settings.
12) RIVERBERO
Level control for the onboard Accutronics® spring reverb.
13) PRESENCE
The Presence knob controls high frequencies, above those controlled by the High knob. It’s an effective and useful part of the amp’s tone
controls. Turn the Presence up for crisp, sparkling clean sounds, crunchy rhythm sounds and aggressive riffs; lower it for darker, rounder
sounds and focused single-note lead tones.
14) SOLO
This control can be activated by footswitch. It boosts your signal level by 6 dB to step up your volume for lead playing in live performance.
