Preamp pedal question
Hi All,
My first ever post on this forum. Mainly an electric player moving more into acoustic.
I own two acoustics, one with a Fishman UST and the other with a K&K pure mini. Both passive without any installed preamps so I’m wanting a preamp pedal to complement these two guitars.
My question regards input impedance. I have heard it said that piezo pickups benefit most from a preamp input impedance of 10M Ohm (found on some boxes) rather than 1M Ohm (found on some others). This begs the question why many boxes only have this lower figure including the one I am considering buying.
Can anyone comment on this 1M Ohm vs 10M Ohm comparison. Is it an issue that should dictate my choice of preamp ?
My other question regards the success (or otherwise) of plugging an acoustic preamp pedal into the FX loop Return of an electric guitar amp (bypassing the preamp stages but retaining use of amp reverb and master volume controls).
But my main question is the impedance matching one ....
Very many thanks for any replies.
