This is a 7-band equalizer 50Hz, 120Hz, 400Hz, 500Hz, 800Hz, 4.5kHz and 10kHz. It also has a level control. The amplitude of the 8 settings is + /-15dB. This is an almost exact copy of the Boss GE7B. The housing is made of metal. The pedal seems sturdy as a whole (so far).
I used it recently with a Cort Action 4 string and a Fender Frontman 25B (3 knobs EQ to noon). Cursors are a little less easy to use than a Boss (I own the GE7) but nothing insurmountable. No unwanted noise when I press the pedal. The switch between on and off is smooth.
Nothing to say: settings are effective. This is surprising for a pedal this cheap (about 20 € in PlugSquare, shipping included). I give it an 8.
For those not wishing to invest in expensive gear without sacrificing quality. It does the job properly. Very good price / quality ratio, I put a 8.
