I ran out of space on my power supply on my bass pedalboard and was looking to move the current one to my guitar board and then replace the one on my bass board. The price differential between isolated power supplies with 7 or more spots is somewhat surprising. I figured this would be a commodity thing and in general pricing would be around the same. Is a Strymon or a Cioks power supply really that much better than an MXR Iso Brick? Why the disparity in pricing? Why do ya'll pick what you use on your board?
