This amp is a unique hybrid combination with a solid state power amp and a tube preamp.  It is capable of a loud clean volume but can also get the added tube warmth when needed.  A wealth of digital effects are also built into the amp giving you unlimited possibilities to change your sound.  The RG75D G3 Plus also features a single 12" Celestion speaker and includes a 4 button footswitch to switch channels, switch between 2 different gain settings (on the overdrive channel), activate a "clean boost" function (for the clean channel), and turn the effects on or off.
