This is a crunch-distortion pedal.
Obviously it's an analog pedal.
Input and output jack 6.35.
Three pots, Level Tone Dist., Respectively, that affect the output level, tone and saturation.
External power supply or 9V battery.
Metal housing except the battery cover and pots, a little fragile indeed, a pity.

UTILIZATION

Configuration is very simple, with three pots are not lost.
It is easily the Son sought by varying the drive and tone.
No manual.

SOUND QUALITY

At the side sound grainy distortion gives a fairly clean side to the crunch, the distortion level varies between clean and distortion effectively reasonable, definitely a plus on that side.
As against the tone control is pretty bad and the pedal tends to eat quite a bit the bass and treble damages for distortion.

This is a really versatile pedal for crunch, with single or dual microphones you can easily find his Son.

OVERALL OPINION

This pedal should be easy twenty years, I was the data it holds up.
Having a crunch-distortion I really like this pedal.
This pedal is really effective in its own tone, but for a reasonable price that choice I would do without hesitation.
