I just bought this power supply. I used an earlier Korg KA 189 power supply on my Behringer pedals with a daisy chain power. This power supply was supposed to be compatible with these pedals (she had been sold as such), but it caused a horrible hum, and most of the pedal LED Delay never went out when I bypassing the effect, so that 'using the pedal with batteries there was no problem.
So I bought the OneSpot and I use it with a garland feeding my 4 Behringer pedals and miracle! More hum, no more breath, and led to the delay pedal off when the effect is bypassed (which is still more convenient).
So any good product. Bought € 25, and I think I could make if I want a dozen pedals with no problem, because with 1700 mA there is enough to see.
The value is definitely excellent.
I'm glad to have discovered this product on Audiofanzine!
