[br]I've just got a new amp and I've noticed that when pushing the spring reverb passed 3 o'clock ish it starts to create a bit of noise, like white noise. At 3pm onwards it's quite a lush/ heavy reverb sound but it still sounds nice so I'd like to see if there is a way of making this quieter or if this is just normal?[br]It's quite an expensive amp (a Bad Cat Cub iii) and is tube driven spring reverb (12AX7). I have replaced both preamp valves and also tried turning the reverb tray the other way.

Thanks![br]Andy
