Sorry if this is in the wrong spot, but I'm not sure where it should go. Feel free to move this, moderators! Anyway, here goes. I'm thinking of getting a power conditioner. Yes, I realize that many people here think of them only as a glorified power strip and a waste of money, but my rack is coming together and I want to simplify setup. Also, I have a power issue. Here's the issue. I live in an apartment building built in the 1960's. I don't even have grounded plugs! So, to make sure my amp was grounded, I bought a grounding adapter and have it going to a power strip that indicates whether or not it is grounded (thus far, it always has been). Here's the problem. When I have everything plugged into my power strip, the sound of my amp noticeably degrades. Is it terrible? No, it's just a hissing noise, but if I disconnect the other stuff (only one thing: a 1 Spot Pedal Power Adapter powering 6 pedals) the hissing is easily cut in half. So I guess here's the question. Which power conditioner would you recommend? I'm not looking to spend a whole lot of money (hopefully $50-60 tops) and am all for used gear. I just want to make sure it filters out "bad" power and potentially emi/rfi stuff if possible. In the end, I plan on using this power conditioner to power my amp, rack tuner, pedals, and a wireless system. Thanks for the help!
