BanTamP XL series features a channel switching footswitch, 6 knobs--specifically speaking, 2 channels can be controlled independently, now we have better control over the volume of CLEAN Channel and DISTORTION Channel, and adjust their GAIN and TONE independently. The JACKMAN has to fill some giant shoes and it manages to have the same mid-gain drive sound that reacts beautifully to your playing and guitar volume. just like the classic rock monster, the JACKMAN needs a bit of help to push it further. The JACKMAN 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. Use a TS-type pedal (like the JOYO Green Legend or Vintage Overdrive) to push it into higher gain territory and hear it sing. 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. The icing on the cake is the Bluetooth connectivity is great to practice with PlayAlongs or to learn songs. 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. Precaution: ***If you want to use the attached footswitch to switch channels, please first set the CLEAN / OD switch to "CLEAN" Please do not dissemble or repair this Amp Head by yourself. Please keep the manual and box for future reference. Mini Amp Head 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. With 2 channels flick the JACKMan amp to the CLEAN channel and use with your array of guitar pedals. A two channel amp makes a guitar head twice as versatile as alternatives and a makes great companion for musicians at practice or on the road. The JACKMan will keep it clean and puts everything in place for the drive of your life. Headphone Out with Built in Cab Speaker Amp Simulation, the amp has a speaker out rated at 8? and can also be operated at 16?. Careful, the amp is small, but 20 Watts is loud and will deliver a handful, you get the same great tone as you would from a mega amp.
