OD + Clean boost blendable. The output is OpAmp not transistor.
The clipping OpAmp is a JRC4558

UTILIZATION

Very Easy, or almost. Let say you can have all clean or mix OD and clean.
The trick is to use it Trebble to max Volume to max and play with the gain and the clean.
It is very agressive with a "Hi Gain" preamp, it actually does a great job. It is not so great for pure vintage tone.

SOUND QUALITY

Sounds great, it cuts right thru, sound great with modern guitar, no problem with it.

OVERALL OPINION

A very good pedal if you good a modern set-up, it would work with a vintage setup, but there is better.
