thanks for reply,i read somewhere,i think jim cunning hams site that his upgrade was a piezo replacement.


Putting piezo pickups in is not exactly an upgrade... it completely changes
the sound, giving you a whole lot more low end and some peaky stuff up top
that the original pickups don't do. You might like that, you might not.

If you put piezo pickups in, you will need to reduce the amplifier gain by
about 20dB and probably decrease some coupling cap values to reduce the bottom
end buildup. (And yes, Cunningham is correct that the hum is reduced a lot
in the process.)

But it's a very striking sound change, it does not sound like the original
to me.

i'll contact Martinsound and see what the options are,i suppose its a thing of,if your gonna do it,do it right.
i was hoping that there'd be a slightly more economic approach.


Economic and EMT plates have never gone together.
