Given the paradox of an amperage from the fire of God and an affordable price, it is normal to find people to complain about the quality. I think we should have a bit of luck. Clearly, all One Spot is not the same, the fault of a quality manufacturing haphazardly (as microphones of the same model with a length of the coils can vaier a factor of two). Mine works, and well, even. Well, it will not if you have the Line 6 I think, but the power supply to the ridiculous price I found helps out well. I "garlanded" to power up to 15 pedal or keyboard (800 mA) and 5 pedals, never a worry! Of course I think I get a Voodoo Lab soon to supply several types of pedals with the same stuff, but ATTEDIT the One Spot's fine with me! Cables and guirlandezs available to meet all expectations. Given the price and my satisfaction (not a buzz), I put a good 10. But if one day I put 9 on Voodoo Lab're not going to believe that the One Spot is better than the Voodoo, it's just that I hope that the Voodoo is perfection, I expect not the One Spot.

Edit of 06/05/2008: I just bought a Line 6 Echo Park, One spot does not create any buzz with the unit, whether fed alone or not (I have 11 pedals chained to try on the same power supply No problem. According to the notice, a second Line 6 in the chain can cause more problems, but it remains to be seen)

Edit 21/06/2011: I just bought a Voodo Lab PP2 +. Not the same price, but the difference is audible. Moreover, it is not due to the build quality of OneSpot, but because of the daisy chains. This OneSpot in backup, is still a good investment for me.
