Anyway the actual point of my post is that I'm a little confused re: impedence matching with the piezo pickups. My main rig is an Ashdown Mag 600r which has both high and low inputs (for active & passive basses) with a range from High Instrument Input Impedance 3.9MOhms / Low Instrument Input Impedance 10KOhms...however from checking out Bob Gollihurs site I see that "Piezo transducers can be in the 1-2 million+ ohms range. ULTRA-High impedance."

...also I've seen some posters commenting that the WAV 4 runs "very hot" for a passive bass..so, which is the best input for me to run the wav 4 from?...also by the looks of things it seems I might need to purchase an external pre-amp like the K&K..(I have a sansamp programmable bass di will this do the job?).
Apologies if these are very simple questions..as I said I'm a complete newb in this area and I just want to get the best out of my new purchase.
Thanks in advance for any advice
cheers
