ECHO 15 Front Panel
1. INPUT
Plug your guitar in here. Always use a good quality screened guitar lead.
2. GAIN
This control adjusts the amount of overdrive or distortion.
When the Clean Channel is selected, low settings counter clockwise (CCW), will
deliver a clean sound. As the Gain control is increased clockwise (CW) the sound
will move from clean into break-up, until at its maximum position, a full crunch tone
is arrived at.
When the Overdrive Channel is selected, the Gain control adjusts the amount of
overdrive or distortion. Low settings, counter clockwise, will deliver a clean sound
on the edge of break-up. As the Gain control is increased CW the sound will become
more overdriven moving through crunch tones until, at its maximum position, a full
distorted lead tone is arrived at.
3. OD (OVERDRIVE)
Press this switch to select the Overdrive Channel. When the switch is in the Overdrive
Channel is selected. When the switch is out the Clean Channel is in operation.
4. VOLUME
This controls the volume of the Clean and Overdrive Channels. Turning it clockwise
increases the volume.
5. TONE
The Tone control allows adjustment of the balance between treble and bass
frequencies within the sound. At low settings (counter clockwise) the sound will be
warmer and darker in character. As the Tone control is rotated clockwise the sound
will become brighter.
6. EQ/ISF (Infinite Shape Feature)
The patented ISF control allows you to choose the exact tonal signature you prefer.
Fully CCW has a more American characteristic with a tight bottom end and more
aggressive middle, and fully CW has a British characteristic which is more ‘woody’
and less aggressive.
7. DELAY ON/OFF
Press this switch to engage the DELAY. When the switch is out the DELAY is off.
8. DELAY TIME
This controls the amount of time and feedback on the DELAY. Turn the Knob
clockwise to increase the time and feedback for a spacious large room feel, and
counter-clockwise to decrease the time and feedback for a more slap-back type
effect.

Connect the output of your MP3 or CD player here. Adjust the player’s volume to
match that of your guitar to enable you to play along. Note: the connection is stereo.
