1) INPUT Connect your guitar to this input using a standard ¼” shielded instrument cable.
2) GAIN This knob sets the gain level (on each channel), and it is the preamp’s most powerful control. It not only determines the amount of
drive or saturation (for getting clean, crunch or overdriven sounds, or anywhere in between), but also plays an important role in tone shaping.
3) MASTER This control is the master feed from the end of the preamp channel to the tube power stage. Each channel features its own
MASTER control thats allow you to perfectly balance the volumes of the three channels, which can have very different sound styles and gain/
drive levels. On each channel, the master control allows you to obtain a wide range of sounds in relation to the gain setting—for example,
very low-gain sounds at high volumes, or high-gain sounds at low volumes.
4) PRESENCE The PRESENCE knob featured on each channel controls high frequencies, above those controlled by the High knob. It’s an
effective and useful part of the channel’s tone controls. Turning up the Presence knob gets you a crisp and sparkling clean sound in channel 1,
or crunchy rhythm sounds for aggressive riffs in channel 2. On channel 3, turning down the presence control gets you a darker, more rounded
tone for single-note lead playing.
5) BASS This knob controls the amount of low frequencies in your sound. The EQ curves of the bass controls are different on each channel.
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.
Also as the gain is turned up, it’s a good idea to slightly lower the bass control for a more balanced sound (starting with the bass setting at
around 12 o’clock).
6) MIDDLE The Middle control regulates the midrange frequencies and it is an important part of your tone shaping. The frequency range it
boosts or 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.
7) HIGH The High knob controls the amount of high frequencies in your sound. It can produce unwanted noise (hiss) or pickup feedback when
really cranked, so it’s best to avoid extreme settings, especially on channels 2 and 3, due to their higher gain. On Channel 3 you may find that
the highs need to be set a bit lower than the other channels, especially for soloing.
8) SOLO) This +6 dB boost is activated by the Smart Controller, and it is optimized for notching up your volume for solos during live perfor-
mance. The SOLO control can only be engaged when the effects loop is active, since it’s part of the effects loop circuit.
