I had considered getting one of these a few years ago - I can't remember how many pedals I had back then, maybe 4 - but the sales rep at my local store kinda talked me out of it. Probably correctly. Fast forward to today, I have since accumulated a Strymon El Capistan and more recently a Klon KTR. These, plus my other 3-5 pedals in the chain (depending), were being powered by a One Spot daisy chain. My wife walked by while I was playing one day, and she said "what is that high pitched squealing?" I hadn't noticed up until then, but one of my pedals was obviously emitting a wicked squealing noise. A bit of experimentation, and I determined that the El Cap was the culprit. A bit of reading online, and apparently the Klon KTR's "charge pump" is partially responsible, although I am sure the total mA draw of my pedals wasn't doing me any favours. I got a few gifts from the local music store, none of which I needed, so I returned them for credit and picked up a Trueton CS7 power supply. Well the squeal is gone! In addition, the power supply comes with an 18V option, so I tried that out on my Timmy and it sounds pretty great! So the CS7 was a good option for me to eliminate noise from my rig. Just thought I would share.
