By virtue of their electrical properties, tubes generate a special waveform when they're saturated, which is why tube engineering has tremendous tonal advantages over solid state or DSP solutions, particularly for crunch and lead sounds. Tubes enter the saturation zone gradually or softly, which lends tube-driven tone its trademark yet totally unique character.

well. It sounds like its not set up correctly. If u take it to a local guitar shop they should be able to alter the bridge so it is correct for the strings ur using ! Or u could just change to a different string gauge. It basically sounds like u have the wrong gauge strings on it. Thats what it probably is. I'm not 100 % sure though :(
