The THR series was developed for any location beyond the stage where a guitarist may need an amplifier. Apart from functionality, the main objective of the amplifier design was to heighten the fun of playing the guitar. The paintwork and colouring only improve with regular use, while the shape and feel of the knobs, screws and handles adapt to the mood of the guitarist. The THR amplifier mimics a tube amp with a power lamp that slowly lights up in orange – like the glow of a “virtual tube” visible through the front grille.
