Hey Miles, I've got a slight problem I'm wondering if you can help me with?
I use a Laney VC30 112, usually ran at about half volume on the clean channel with a Hotplate. Today whilst playing I noticed a high pitched squealing coming from the amp. It happened with both my guitars, and with and without my pedal board hooked up (so I'm sure its not something caused by my pedals)
I'm thinking it could be a tube problem, but the amp was completely re-tubed only a month ago. Plus on average the amp only gets used about an hour a day.
Thanks in advance for any help you can give me.
