the controls have a good feel to them for adjustments... not the best, but good quality parts were noted for this unit for just a basic pre amp... if you want a simple pre amplifier, without spending a lot this unit will do just fine....

Pro unit, this thing is too good to be true

work!!!!This unit is awesome!!!!

loudness button really brings out the clarity and punch this unit can do...

I just received this unit a couple of days ago, but so far I like it quite a bit, especially for the price.
