The Bogner Shiva Tube Guitar Amp Head with EL34 Power Tubes features two highly evolved channels, capable of clean tones that shimmer like icicles in winter, and tube saturation so powerful it should be illegal. Foot-switchable boost function for both channels, variable for channel 2. EL34 models are whopping 80W and have a nice throaty growl with aggressive English-style midrange to punch thru the mix. The Shiva also has a tube-bufferedm series FX loop. The Shiva channels the synergy of one's heart and hands.
