You got it, Sasha, it's a fine tuning change we made to improve musicality while ensuring low hum.

Thanks Woody,

I have recently changed my templates to 12.7mm to accord with imperial 0.5" standards widely used in the US; but I have to say 11mm does look better when you properly dress the leads, more compact.

I have now received the pcbs, hope this week to commence despatch.

Cheers,

Hugh
