Planning on getting the powered version. I guess I'll inquire first. I use the Dex through the return effects input on my Acoustic Image Contra, bypassing the preamp as I understand it, and get plenty of volume.Are you planning on getting a powered MAS 1/6 or a passive one? Conceivably, you could just connect the ToneDexter directly to powered one, however I’m not sure if the output of the TD alone, has enough voltage to drive one. Perhaps a passive one would best.
