entirely possible for this humming and other noise to rise to a level that deactivates the

and therefore becomes audible. My advice is to stay as far away from

transformers and power units as space allows.

¼" unbalanced input jack. Plug your guitar in here using a shielded cord.

Depending on the type of cord and its shielding, you may occasionally encounter

interference from sources such as radio stations or powerful magnetic fields. When

this occurs, try connecting your guitar to the amp using different cords. What's more,

to minimize signal degradation due to high-frequency loss, use the shortest cords

feasible (as a rule, the shorter the cord, the less susceptible it is to high-frequency

attenuation).

Pressing this button ups input sensitivity, thereby increasing the amplification factor

and the amount of distortion in all four preamp channels , , and . The

LED above this button lights up to indicate is active. This feature can also be

switched via MIDI program change or Custom Z-9 Footswitch.

Obviously, the difference between Lo and High Gain is the latter gives you more

preamp juice. But I also tuned frequency response to suit each channel's gain structure,

which is a long-winded way of saying the four channels give you eight great sonic

choices. Depending on the selected channel and Gain knob setting, the spectrum

ranges from pristine clean to ultra saturated lead tone, rich in overtones and gain

reserves for screaming solos and crashing power chords. Whatever tones your style,

genre and whims may demand, you'll find it between these two extremes. The options

are too numerous to mention, so switch back and forth between Lo and High Gain in

each of the four channels to get to know their tonal characteristics and make the most

of these eight fundamental sounds.

Gain control for Channel 3. This knob determines Channel 3's input sensitivity; use it to

dial in the desired amount of saturation level.

Depending on Gain knob and Gain option (19) settings, Channel 3's gain ranges from

middling to extreme, which translates to big power chords and mean leads. Note that

Channel 3's midrange is scooped - that is, not as dominant as Channel 4's - lending

Channel 3 a distinctive tone quite unlike the other.

Extremely high gain and volume levels in Channel 3 can produce powerful

feedback. Avoid feedback squeals; they can lead to hearing loss and damage

speakers! At higher volumes, back off the Gain, Treble and Presence levels in order to

prevent unchecked feedback!
