Features

The LT-ECHO 15 is the practice amp, packing all the great tone and innovative features you would expect from a Blackstar. The patented ISF (Infinite Shape Feature) circuit gives you infinite adjustment over the characteristics of the tone control network and takes you from the USA to the UK and anywhere in between. So now you can effectively design your own tone and finally find 'the sound in your head'.

The LT-ECHO 15 also has a fully specified speaker emulated output allowing any guitarist to get amazing tone straight to tape or disk, or through headphones.

Add to this an MP3 / Line Input, allowing you to jam along to your favourite tracks, you have everything you need for practising or recording. Gain 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.

The patented ISF allows you to choose the exact tonal signature you prefer. Fully counter clockwise has a more American characteristic with a tight bottom-end and more aggressive middle, and fully clockwise has a British characteristic which is more 'woody' and less aggressive.

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.
9. MP3 / LINE IN
   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.
10. SPEAKER EMULATED OUTPUT & HEADPHONES
    This output emulates the tonal characteristics of a guitar speaker cabinet and provides a natural overdrive tone for connection to a recording device or mixing desk, and for use with headphones. Note: when a lead is connected here the combo's internal speaker is disconnected.
11. POWER INDICATOR LIGHT
    The power indicator will light when the amplifier is switched on.
12. POWER
    This switch is used to turn the amplifier on and off.
