Sounds OK for a very very very inexpensive device.  The issue I have with it is the knobs are very sensitive. No resistance so they move when you hit the switch.  Strange but the gain knob changes the volume.  I have to keep resetting the knobs.  Plus the volume is very loud at the bottom of the pot.  As soon as you turn it up it gets loud very fast.. No really low volume setting.  I also think that if as advertised if your amp goes down you can go direct into the PA, should have a balanced 600 ohm output, not the 1/4 inch High Z one... So you have to go from this into a DI to get into a PA....

it is great for what i use it for  - that is dropping at the end of a chain to color the tone properly for distortion/overdrive the gain on it's own sounds good too- I would give it 5 stars if it was a little cleaner - you can't really bump the level w/o getting a little grit  - which has pluses and minuses but overall worth the purchase
