Markbass Little Mark Tube Transducer by Googe published on 2010-10-18T21:01:24Z This is my Markbass Little Mark Tube amp with a transducer attached. The first part is with the mic attached to the top above the input and then moved back to the fan. The second sound is with the mic on top over the fan. The third sound starts out over the fan and is then moved over the power supply, which is right next to the fan. The last part is over the power supply. Genre SFX
