1.) Mic/Line Input - this is a 1/4 2 conductor input jack for plugging in a Hi-Z microphone or instrument. It is intended for
microphones but will accept other instruments as well.
2.) Guitar Input - this is a 1/4 2 conductor input jack for plugging in your instrument. It is intended for guitar or Hi-Z microphones
but will accept other instruments as well.
3.) Mic/Line Volume - this control is the output volume control for the mic/line input. Slowly increase the control to increase the
volume. If you are using a high impedance microphone, be careful when increasing the volume. Depending on mic position, it
may feedback if mic is in front of speaker.
4.) Mic/Line -
this switch will select a mic or line level input. If you are using a high impedence microphone, be careful when
increasing volume. Depending on mic placement, feedback may occur.
5.) Guitar Volume - this control is the output volume control for the guitar input. Slowly increase the control to increase the
volume. If you are using a guitar with an on-board preamp, set its level for a mid position before increasing this control otherwise
distortion may occur.
6.) Active - this switch will place a -20db pad in the circuit which will allow use of active on-board electronics from pre-amplified
guitars. This will help keep the signal extremely clean.
7.) Frequency -
this control is a tight Hi-Q cut filter notch with an extremely narrow width. It sweeps between 50Hz & 500Hz and
fine tunes the midrange of the acoustic guitar. This helps elimate unwanted ringing tones. It is preset to -10db.
8.) Low - this control is the bass control. It is active and set to boost or cut frequencies at 60 Hz. This will effect the low frequency
signals. Turning it counterclockwise, the low will be rolled off -18db. Clockwise, it will boost +18db. Especially good for cleaning
up preset patches or making thin toned guitars sound fuller.
9.) Mid - this control is the midrange control. It is active and set to boost or cut frequencies 1.5KHz. This will effect the mid-low
frequency signals. Turning it counterclockwise, the low-mids will be rolled off -12db. Clockwise, it will boost +12db. Especially
good for cleaning up guitar overtones.
10.) High - this is the high frequency tone control. It is active and set to boost or cut frequencies at 5KHz. This will effect the high
frequency signals. Turning it counterclockwise, the highs will be rolled off -18db. Clockwise, it will boost +18db. This will add or
subtract the high end shimmer and clarity.
11.) Reverb Level - this control adds the spring reverb and mixes it into the main signal buss. Reverberation creates a trail like
effect with the sound. It lets the notes hang in the air longer, extending the sound.
12.) Chorus On/Off - this is the switch to turn on and off the chorus circuit.
13.) Chorus Level - this is the Speed Control for the chorus circuit.
14.) 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.
15.) Jewel Light - this jewel light lets you know that the amplifier is on.
16.) 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.
Effects Loop I/O - these are 2-2 conductor 1/4 jacks. This will allow an external effects device or equalizer to be patched back in before
the power amp section in this amp. One is send and the other is return.
Footswitch Jack - this is a 3 conductor 1/4 jack. This is for hooking up a footswitch to turn on/off the chorus and reverb.
