Behringer UM300

It sounds like a Metal Zone.. if that's what you want this is a bargain pedal. It has a huge range of tone (too much really), the mid EQ has a massive range is is super sensitive. There are insane amounts of gain in this pedal, more than you could ever want or need. The range of usable sounds is pretty small in my opinion but the same can be said of the Boss pedal. For the price it's a bargain, my only complaint would be the cheap plastic enclosure.

I might have just used it 2 or 3 times before its jack broke done. Not so good tone but if you just need a cheap distortion to pedal there you have it.

This pedal is supposed to be an exact Metal Zone copy. I found that it has too much of this mid honk (the MZ has it too but less prominent) that I can't get rid of. Plastic enclosure and plastic jacks are definitelly not optimal but you get what you pay for - I wouldn't gig with it but for home use I don't think it will break.

The pedal sounds okay on it's own but it probably sounds better through a proper amp. I would be careful with the level-knob as turning it past the midway will cause eardrum-splitting feedback.
The knobs are too close to each other and and too stiff. It is very hard to turn them without accidentally turning other knobs.

It does the job and is worth its price.Would recommend to someone who's looking for cheap pedals. Otherwise would look up for something else.

When it was written ultra metal I expected the sound of Slayer but not black metal

You cant argue with the price of this pedal for what you get compared to a lot of the other distortions available. plastic casing so dont go stamping on it. Perfect for something to get started on or practice with. ** Please dont go playing live with this pedal - humans should not be subjected to this pedal at high volumes.** I bought it to put through my little practice amp for a bit more gain.
