The functionality is workable. No hum or noise heard when use. Tone won't be ruin when bypass or effect on.
For pros,
1. Affordable price:
I think there is no other 7 band graphic equalizer pedal product can be purchased by this affordable price.
2. Good look appearance:
In my opinion, this pedal has a BOSS-like appearance design and golden ratio (well...maybe almostly) dimension. The other similar low price EQ don't looks as well as this one. Moore is too slim, Artec si too corny...etc. Well, no offence, I think this is subjective and I write what I think.
3. Function workable:
This is the most important. Every frequency band worked as what frequency written.
For cons,
1. Not true-bypass:
I suggest Thomann should stop to advertise it is a true bypass pedal. I found the foot switch is a non-lock type and there are only 2 contact been controlled. It 's impossible to implement "true bypass" by this switch component with only 2 contact. But as I described above, I feel it not ruin my tone when bypass or effect on. I think non true bypass won't be problem.
2. Seems to be fragile
Although it looks like a BOSS pedal but the plastic part is thinner than and inferior to BOSS's. I haven't broken it after several times kick but I can feel it not stable as pedal from other major manufacture
3. Hard to find battery socket:
I don't have other pedal with same design for battery install. The manual inside doesn't describes it. So I have no idea to install battery. I have to youtube it myself then I learned how to install a battery.
4. No center detent on faders:
As other review describes, there is no center detent design on all the fader POTs so you can't adjust the level to precise 0dB. I can only ensure by aligning the line mark.
As a bass beginner, this pedal does be helpful to me for trying to be up on adjust tone of bass guitar. I think my penny is worth. This is absolutely best equalizer pedal choice to people has low budget.
