1.) CD/Tape Input - this 1/4" 3 conductor jack will allow you to plug in a CD player, tape or any other source
to practice along with. It sums the left and right signals into a mono signal. To control the volume of the
source, adjust the output volume of the device. We suggest you turn the volume all the way down then
plug in and adjust the volume according to your taste.
2.) Guitar Input Jack - this is a 1/4" 2 conductor input jack for plugging in your instrument. It is intended for
guitars but will accept other instruments as well.
3.) Lead Gain - adjust this clockwise to increase the amount of distortion you add to the overdrive signal.
Used in the lower ranges of the control, you get a less distorted sound, a "bluesy" tone. As you increase
the gain, you add tremendous amounts of distortion to the signal for a harder edged "crunch" tone.
4.) Channel Switch - this switch selects which preamp you are using. It will switch between the Rhythm and
Lead channels.
5.) Lead Volume - this control is the output volume control for the Lead Channel. It follows the same tone
circuit as the other channel. It's gain structure is determined by the lead gain control but this serves as the
overall master volume for this channel.
6.) Rhythm Level - this is the volume control for the clean channel. It's gain structure is preset for maximum
signal before distortion and determines the output level of the amp.
7.) Bass - this control is the bass control. It is passive and set to shelve frequencies at 65 Hz. This will effect
the low frequency signals. Turning it fully clockwise, the signal is left alone. Turning it counterclockwise,
the lows will be rolled off.
8.) Preamp Switch - this switch selects which preamp style you are using. It will switch between the classic
USA warm sound or Brighter sound famous in the UK.
9.) Mid - this control is the midrange control. It is passive and set to shelve frequencies at 1KHz. This will
effect the middle frequency signals. Turning it counterclockwise, your signal will "hollow out" the mids
which is popular in today's music.
10.) High - this control is the high control. It is passive and set to shelve frequencies at 5KHz. This will effect
the high frequency signals. Turning it fully clockwise, the signal is left alone. Turning it counterclockwise,
the highs will be rolled off.
11.) Digital Effects On/Off - this switch engages the digital effects section.
12.) Effects Level - this control adds the digital effects section and mixes it into the main signal buss. Several
different effects are available.
13.) Program Select - this switch will select any of eight different effects. 2- Reverbs, 2- Delays,
Chorus/Reverb, Flange/Reverb, and Tremolo.
14.) Jewel Light - this jewel light lets you know that the amplifier is on.
15.) Power - this switch turns on and off the AC power to the amp.

Speaker Out - this is a 2 conductor 1/4" speaker output jack. This will disconnect the internal speaker and
allow an external speaker cabinet to be employed. Rating is 8 ohms.
Line Output - this is a 2 conductor 1/4" line output jack. This will allow an external amplifier or mixing
board to be supplied with the signal from this amp. This signal is attenuated and comes from the power
amp.
Headphone Jack - this is a 1/4" 3 conductor jack for plugging headphones. It will sum the signal and put
the sound in both ears, thereby creating a pseudo-stereo sound. Volume will be determined by the volume
control on the channel you are on. It will disconnect the internal speaker when plugged in. This will allow
quiet practicing.
Footswitch Jack - this is a 3 conductor 1/4" jack. This is for hooking up a footswitch (optional) to switch
channels (tip) and to turn on/off the digital effects (ring) .
Suggested Settings
(These settings are general starting points. They
are designed to get you close to the sound you
are looking for. If the control is not shown, then it
doesn't apply to this particular sound. )

Clean Rhythm or Country Guitar - these settings are the basic clean sounds and for general rhythm
guitar, country lead guitar, and funky/chunky rhythm sounds. Usually, country guitar is a brighter, more
trebly edged sound. The bottom end depends on what type of guitar you are using. Digital Effects
depends on taste.
Rhythm guitar is mostly a clean full type of sound. A little less treble than the country sound and a bit
more midrange. Digital Effects, again depends on taste.

Blues Lead or Mellow Crunch - this setting is particularly useful in blues or softer rock songs and It
is good for leads as well as rhythm parts. It is good for power chords in back of leads.You need to
switch to the lead channel to make these settings work. Blues, depending on the guitar you use,
usually adds treble but with more midrange and a "fat" bottom end. This setting does not have as
much gain as full out crunch, adjust the gain control to the amount of distortion you desire. Blues
usually has a reverb trail on the notes. Chorus is sometimes used to create a vibrato style sound.
Adjust to taste.

Alternative/Harder Edged Rock - this setting will deliver more of a cutting tone. Whether used for
rhythm or lead sounds, it will "cut" through the drums and get you heard. If you need more "grunge",
increase the gain control for more distortion. This style of music requires a slightly thinner, harder
edged tone full of midrange. Less reverb is required as it tends to muddy up faster songs but Chorus
give the tone a fatter fuller sound. Adjust to taste.

Heavy Metal/Maximum Crunch - this setting is a good starting point for the "notched out middle"
sounds associated with metal and heavy alternative sounds. Adjust the Treble, Lows, and Digital
Effects to taste. Usually, for a rhythm tone, you want to have more lower end and less for leads.
Distortion is an integral part of this style of music and this amp delivers it quite well.
