Lil Rapidos opinion because there is not that much to say about an equal.
A switch
+ A 6-band guitar volume
In / out
9 volt battery or input.

All in his early 80's metal casing solid.

One could blame the low # of bands, but ...

UTILIZATION

It's simple, a little flick when one is 0.
boost up to 18 or - 18 dB

SOUND QUALITY

- Transparent Bypass
- Use in the loop of the amp, it works well, also upstream to the amp cruncher
I use it with an electric guitar.
- No breath.
Works well.

OVERALL OPINION

So cool, paid € 35 for OCCAZ, it makes the job that the Boss mm (tested)
Not much to complain about, it's the only pedal I have used EQ. How it works well.
I use it in the loop as a clean-boost for solos (I hardly touch the EQ settings, just to win treble + present)
