Hello,
I have an acoustic guitar which have an undersaddle piezo pickup which needs a preamp which is built in in the body of the guitar.
I want to add to these factory equipment a bridge position piezo transducer which doesn't need the preamp because have a discrete high output,i add after this transducer a log pot of 500k,and i connected the output together with the output of the preamp to the same endpin jack of the guitar.
All working fine.
My questions are,do i have to add a series resistor?
Is the preamp short circuited?
the output impedance of the preamp is 3.5k,of the piezo without preamp at the order of Mohm...
Thanks for the answer in advance!
