Enough outlets until your board overruns.

The art of daisy chaining is rampant but at least there's enough power to spare with this. I find that with simple math, 100mA is easily spread out depending on what I'm using. 1 outlet for my Nova (12V), one for my HoF, 1 for my Signa (18V), 1 for my MXR O.D, Tuner AND Analog Delay at once. I think I have enough space for a few more. No fizz, no hums, all quiet. Absolutely perfect.

Great compact power supply

Affordable price, 5 fully isolated outputs, multiple voltages (9,12 and 18v), small footprint - what's not to like? It's great for simple pedalboard and has enough power to do its job. ISO 5 is very silent, too. Build like a tank, definately worth taking on tours!

I like it

I intend to get the next one up ASAP since I have more pedals now. Love this though.

very good

Perfect for what I needed - isolated outputs,18V. The only issu I an pont is the silkscreened text is very weak and with a minimal scratch it comes off.
