I did some further research on the internet and found that the PVP12 originally is ment for guitar. It has input and output and must therefor be connected between source and amplifier.
I wonder if this can be used with KN7000 because there is only one connection for the expression pedal. I think that every expression pedal only consist of a potentiometer which can be changed to meet the requiredvalue. Maybe I am wrong.
Is there any expert on the forum that can tell me about the electrical diagram of the original Technics expression model?
Hope to get the answer soon because I have a reservation at seller up till tomorrow.
