to make a long story short, I’m wondering if I can use a Morley AB switcher to switch between preamps. I have a rackmounted Hellborg pre and a SansAmp. I’m plugged into the front of the Hellborg coming from the tuner which comes from my wireless. How I’m envisioning it is Hellborg pre out to A of Morley Sansamp pre out to B or Morley and output to my Hellborg power amp. Would this work? If anyone has any experience using an AB to switch between preamps let me know!! Thanks.
