If steelvibe (Sean) is correct about the TWA'a input impedance being 500Kohms, it obviously wasn't designed to accommodate a passive undersaddle pickup. A passive mag pickup, a passive Pure Mini or any active system are still decent options if you're connecting directly to the TWA. (With most passive undersaddle pickups, you'd need an outboard preamp between the guitar and the TWA to get a full and pleasing tone.)

If you are just amplifying for your own enjoyment at home, steelvibe's suggestion to use headphones would certainly enable you to avoid feedback problems, whatever the pickup.

If you're looking to amplify loudly in a venue somewhere, that's a whole different ballgame.


In what situation are you having the feedback problems? I can tell you from experience that a Baggs M80 is a lot less feedback prone than a Pure Mini soundboard pickup. If you.re having problems with the M80, don't expect to be able to do the exact same procedure and have no problems with the Pure Mini.
