All the Strymon multi-power supplies are just the best. The Ojai is the smallest of the bunch but, as expected, it is very well and robustly constructed. Powers every pedal perfectly, without any noise in the chain. I was initially thinking of buying the Zuma 300 as it has the power supply integrated (one less brick to deal with), BUT actually, having the 9V inputs and the power supply separate allows me for more space flexibility in the pedalboard. As other reviews mentioned already: It only has 5 inputs but you can get an expansion if needed and use the same power supply brick. Yes, Strymons are expensive no doubt, but in my opinion worth every cent. If you are serious about your pedal chain power and sound these are a no brainer.
