Hi guys, I just bought my first ever electric and I've been playing it for about a fortnight using my friends Zoom 505 II multieffects processor. The only setting I really like and use regularly is the distortion I've made using values I found on a website. Anyways, I've now decided not to waste money on an expensive processor and slowly accumulate various expression pedals instead, starting with distortion first. Firstly, is this a good idea? And secondly, could you guys suggest some good distortion pedals within 100-200 US dollars that would be suitable for playing all genres of metal well, especially heavy and thrash? I've got my eyes on the Boss Metalcore, but reading the user manual makes me wonder whether it'll be suitable for playing the main genres of metal rather than the sub-genres. Could you guys suggest some better alternatives, if there are any?
