The features on the pro power (version 2) pursuaded me to buy it over the similar but slightly lower output voodoo labs pedal power 2 as I have several current hungry digital pedals on my board. The extra current output per channel (including the 2 high output channels with 350ma per each) put it ahead for my pedal setup versus the voodoo labs. The first one arrived from Thomann with a grounding problem on the 8th output, Thomann processed a return (frustratingly and indfexibly insisting on all cables and connections also being returned, meaning a complete pedalboard disasemble and power cable removal was needed) and after a couple of weeks I received a replacement unit tonight which works fine but has a loose power connector which pops out of the unit when you remove the AC cable, meaning care is needed. Frustrating but not enough to deal with the trouble of a second return so I'll live with it, but am very disappointed in the brand. This is my first Carl Martin product and is likely to be my last...
Overall, the features are very good. Fully isolated and regulated DC including independent 9/12v switching per channel and 120/250v AC input switching, but I simply don't trust Carl Martin build quality anymore. I had reservations after hearing/reading similar problems elsewhere, but after my (frustrating) experience here with both the brand and the inflexible Thomann returns process, I would be very careful with CM stuff in future.
Tone and clarity is great from this, no question, and all the fidelity and high end is preserved in the guitars signal. If you absolutely need the high output (6x150ma and 2x350ma at 9v) then take the risk on the pro power version 2 but if you don't need the extra juice go for the voodoo labs PP2.
