Sound, Character and Amp Modeling
The Silver Jubilee series was based on the JCM800 2203 and 2204 models but added new features. The 2555 has a preamp with three gain modes: Clean, Rhythm Clip and Lead. Softube says the preamp is higher in gain and somewhat darker and smoother than the JCM800.
The power amp tubes can switch from pentode to triode operation, which halves the output and makes the power amp distortion silkier and less aggressive. The developer states that this behavior has been modeled in the plugin.
