I want to get a reverb pedal I think. Mainly for lead lines, sometimes tremolo picked, in a (extreme) metal setting, but also some cleans probably. I suppose it would live in the loop mainly, but I think it could be cool to try reverb in front too, but don't really know. I often tend to like music where the reverb is pretty huge, so I maybe don't want something that's too subtle. I'm really not sure what to get, there's so much out there. I've looked at Boss RV-6, TC HOF, Digitech Polara, and also the bigger ones from Strymon, Empress etc. And also the EQD Afterneath looks cool. But since I haven't really used a lot of reverb before I don't know what would do the job best for me. Also I've read some people talking about lack of headroom on pedals, which concerns me a little bit, since I mostly use EMGs. And if I use the pedal in the loop maybe that could be a problem? Should I be concerned about headroom?
