Some strange things are happening now. They might be perfectly normal, but as I bought it second hand I'm unsure of the intended manufacturer behaviour.
1. The thing is loud. I mean really really loud. In a gig practise situation, I would have the HD500X output set to max, the channel volume set to high on the amp, then the master volume at around half way. Now, if I have that I get serious volume/feedback from the amp. I've had to reduce everything quite a lot. So much so it's messed up a lot of my presets!! Sounds like a stupid comment, but I'm wondering if it's supposed to be quite that powerful (subjective I know).
2. If I roll my guitar volume down to 0% I get a quiet weird clicking/hum sound. That's even if I plug directly into the amp. It's not so much of an issue, but highlights something that might not be right.
Any ideas?
Thanks :)
