Hey guys, i'm gonna order some new pre tubes in the next few days so thought I might as well get this sorted at the same time.. When using the DI on the V8, there's a lot of hum coming out of the PA, especially when I use gain II and it's on post EQ. Also, when I turn up the master, there's quite a bit of hum and noise. I've also noticed when playing in my bedroom that when I use gain II and sit facing away from the amp, there's a lot of buzz as well (still is when I face the amp, just more when I face away), which I suppose would be grounding issue of some sort? Anyway, just wondering if one of the preamp tubes (especially the DI/gain II factor) would be causing this? If so, any of the V8 owners know which one, so I could replace it? Also, could the grounding issue in my room etc be a dodgy cable perhaps? At a battle last year, the bass amp (not mine) fell from a stack about 5' high and bent the end of my planet waves lead, the shop nearby replaced it with a cheap-o jack end and i've used it ever since. Could that cheap end be an issue (never really had a problem with my other amp though). Cheers!
