so i have had POD farm for quite some time and it sound pretty good for the most part. i have 2 really big problems though. number one and probably the most important of the 2, is i cannot for the life of me get it to produce waves. i have my guitar right into my firestudio tube and it sounds good, but when i record there are absolutely no waves at all, just one straight line. ?? ive tried adding in this DI ( [ame]http://www.amazon.com/Behringer-DI100-Ultra-DI-Direct-Box/dp/B000CCSWPQ[/ame] ) so i can adjust the xlr preamps but it does nothing and makes it have feedback. any thoughts? also, when i play 'juns' and mute it with my left hand, it makes this sort of swooshing noise after each one. ive adjusted the noise gate and cant seem to get it to go away. ideas?
