    Just want to ask for help from you guys because i have a project to make which is a power supply for my guitar pedals. Problem is i want to eliminate the transformer for it to be more portable, i mean smaller size.. I want to ask a little bit of information from you guys regarding this matter, Is it ok to use 1n4007 as a bridge rectifier so that i could directly connect the plug to the ac outlet (220Vac)

    tnx in advance for any help!! i would really appreciate it..
