Its a typical rock sound but its also very good for blues. The main advantage is the sound character. Don’t expect a Mesa or Fender Twin clean sound. The first channel provides a crunch sound at high volumes (but it depends on the guitar).
The distortion of the second channel provides a big ACDC and Lenny Krawitz rock sound. The sound character is amazing. You have the impression that youre playing with an authentic amp.
Considering that these amps are easy to tune, I thought I could increase its performance. I first replaced all condensers with high-quality components (power supply and signal sections). The lows didn’t increase but the sound became a bit clearer.
Small technical correction: the distortion of the second channel is produced by diodes. Some people say these diodes help the amp produce a higher distortion but the truth is that the amp overdrives thanks to the diodes.
