A: Yes, an external preamp can be connected to the instrument input of the Lowdown, be sure to send an instrument level signal rather than a line level signal to avoid clipping and/or damage to the Lowdown. An external pre-amp can also be run into the MP3 input jack, which would relegate the Lowdown amplifier to a powered speaker.
