alright, I am buying two boss pedals, CE-5 and DD-3, i know both can be powered by Boss PSA-120S adapter. Just need to know whether that adapter can supply power to these three pedals

MXR Dyna Comp, Cmatmods Ratified(Rat clone with extra tone switch) and Polytune Mini

P/s can any recommend me cheap but good pedals? just chorus, delay, comp and distortion, besides above mentioned?

I've got the UK equivalent of that adaptor and it powers the full size Polytune and an MXR Custom Comp just fine. Can't see any reason why it wouldn't work with your tuner and compressor. Not sure about the Rat clone, sorry.
