V20 Nitro amplifier

The Granger V20 Nitro valve amplifier is a 20 watt, high gain powerhouse, ready to rock any studio or club. The controls feature Presence, Master Volume, Bass, Middle, Treble, Normal Channel Volume (Gain), and Lead Channel Volume (Gain). A 2-button footswitch controls a mid/solo boost as well as channel selection. The preamp consists of 3 ECC83S valves. The power section runs on two 6V6S in push-pull (Class AB). A solid state (diode) rectifier and ample power supply filtering produces tight, punchy low end. For the service-minded player, an external bias adjustment with low voltage test points allows the user to bias the amp when replacing valves without removing the chassis (standard feature, only requires removal of the back panel). The 1×12 combo features a Warehouse Guitar Speakers 12″ Reaper speaker. Other speaker options are available upon request.
