Can I get SVT3 owners thoughts on the Tube Drive control? As people say, it does run counter-intuitively in that it is supposed to be more 'tubey' turning anticlockwise, but really all mine seems to do is make the volume quieter and slightly more dull! I'm certainly not complaining, as the head sounds generally valvey anyway, but wondered if it's something wrong with my head? I've had it serviced and new valves (and biased) but it's just the same. Anybody else find it useful knob?
Also, while I'm at it, I tend to run the gain so that the peak LED comes on nearly all the time. It doesn't distort unpleasantly, in fact it sounds great, but am I damaging the head or shortening the valve lifespan by doing this?

Its less than 2 weeks old from new and you've had new valves and a service?
