The Granger M502 Solo Plexi valve amplifier is hand-wired, all tube, inspired by the famous 50 watt master volume amps of the late 70's and 80's, but with two master volumes which are foot-switchable. All the classic tones that defined over a decade of hard rock anthems, with the ability to switch to a solo volume and back to a normal volume. The controls are simple - Presence, Bass, Middle, Treble, Preamp (gain), Master Volume, and Solo Volume. The preamp consists of 3 ECC83S valves and power is rectified by our own Premium Rectifier board (UF4007 diodes) to produce a punchy, tight powerful low end. The power section runs on two EL34 which produce well over 50 watts when fully overdriven. For the service-minded player, an external bias adjustment with low voltage test points allows the user to bias the amp when replacing output valves without removing the chassis (standard feature, only requires removal of the back panel). Custom options include Ultimate FX Loop, passive effects loop, tolex & piping change, and a custom cover with the Granger logo.
