The amp operates with a single 12AX7 tube in the preamp and uses a solid state power amp. The FX loop enables you to put your time based effects (or Phasers, Flangers and Choruses) behind the drive section and keep the effects sharp and not prevent them from being too muddy. Because of the High Gain structure of this amp, a noise gate, like our ?Gate of Kahn? is a good idea to make your heavy chords nice and tight. The amp also has a CLEAN channel that can take pedals really well, which makes it flexible and a great little companion for many situations where your ?big? head is just not sensible. The amp has a speaker out rated at 8?. Careful, the amp is small, but loud? its 20 Watts can be quite a handful. If you want to practice quietly, use the built in headphone out with speaker emulation. The icing on the cake is the BLUETOOTH connectivity. Easily connect with your BLUETOOTH enabled device and play music through the BantamP. This is great to practice with PlayAlongs or to learn songs.
