So what is the best bang for the buck when it comes to compressors? MXR has a number of them I see. Their 'block' logo one is pretty cheap price wise, but maybe not very well liked. Trying to stay around $100 or less, new or used. Want to use it before a Skreddy Rover Fuzz, od pedals in general, to add sustain, but also for clean stuff. Don't want a noisy one, if that is possible. Any suggestions?
