My friend Terry made a clear plastic jig for fitting K&K contacts to the bridge-plate - easy peasy to use, and it places all three piezos at the same time - a piece of piss!

I’ve never heard an under-saddle transducer that I liked, and I will never, ever have barn-doors, pre-amps, volume controls, batteries etc. in my guitars - that stuff belongs outside the instrument AFAIC. But, like most things to do with guitars, pickups are subjective and my poison may well be someone else’s meat!

Keep on pickin’ and grinnin’!
