Coron Distortion 15
a 1981 Coron brochure
Distortion 15 has been developed to make beautiful distorted sound with your guitar, piano or other instruments.
The distortion control makes soft, precision distorted sound at lower level position, at middle level you can get a tube amplifier type distorted sound and at higher level you can get hard type distorted sound like Fuzz tone.
This Distortion 15 has much higher output, it about three times than ordinary other units.
So, you do not need to use a power booster unit for balancing Normal/Effect levels, and also you may use this unit for a power booster at lower side position: these meaning are depending on your instruments output level.
