[sdiy] question: a simple blend circuit?

[Daniel Englbert]

Simple solution ... get a pot, on one out-side terminal put input A, on the 
other outside terminal put input B, in the middle terminal is the output...

wow, really? i thought it may be that simple, is it true? !

what type of pot 250k?


---------------------
original question

hi, i'm a relative fool when it comes to diy stuff, building guitar pedals 
from diagrams and kits is all my experience..

i enjoy reading this list nontheless, i find the subject really interesting

anyway, i have a question i was hoping to get some help on if anyone has the 
free time

i want to make a simple blend circuit for my bass guitar
i've been experimenting with piezo transducers along with the standard 
magnetic pickups

what i want to do is have a potentiometer control the blend between the two 
sources
so for example when the knob is turned fully to the left the magnetic 
pickups are passed to the output jack, if the knob is fully to the right 
only the piezo pickups are heard. anywhere inbetween would just be a mix of 
the two
i'd probably drill out an extra hole for this knob..

i was thinking of housing this in the control cavity where the standard 
volume pots are so the component count would have to be low...

is this hard to do? do i need opamps and a little perfboard? i have no idea 
how to do this, if anyone could help or point me to some schematic (or 
better yet component wiring diagram) i'd be SUPER happy!!!

i could barter some litttle bits of gear for the help! guitar pedals or 
something like that

thanks for your time
