Hi. New member here. I've been lurking a long time and decided it's time to join! I play a good number of musical theatre pit gigs, and I often double on bass guitar. For years I've run both upright DB and BG into an a-b switch and then to a Sansamp para-driver. The Sansamp handles the piezo and I use the volume knob on the BG to match levels. It works, but now there are many options. EA makes a sweet doubler 2 channel amp, and there's a new Bassbone OD, or the V2, which also can handle the piezo impedance. Basically my questions are: Is the Bassbone gonna be quieter? My Sansamp has a little hiss. Nothing terrible but it's there. What are the advantages of a 2 channel amp. The EA is $$$ and a new pedal like the bassbone is a lot less. With the amp, you still have to buy a selector switch. Thanks for the input.
