The Granger M100 "SuperPlexi" valve amplifier is a hand-wired custom reproduction of the legendary 100 watt amp that defined arena rock. Townshend, Hendrix, Van Halen - all names synonymous with huge crushing rock anthems and their larger-than-life sounds. This 100 watt monster carries on that tradition, and a little more. It is built like a tank, based on tried and true circuitry, but features key component value selections that bring out the sweetest "Plexi" tone possible. Clean tones are easily achieved at any setting by rolling off the guitar volume. As with some of the vintage amps of the 60s and 70s, each channel has two inputs, one high and one low impedance, and a volume control. A (post phase inverter) master volume (Ken Fisher Type 2/Lar-Mar PPIV type) can be added to achieve overdriven tones at lower volumes (recommended). Each channel shares the standard Bass, Middle and Treble tone stack and Presence control. The inputs can be jumpered to utilize both channels with channel 1 being the lead and channel 2 being the normal voicing. The preamp consists of 3 ECC83S valves and power is rectified by UF4007 diodes to produce a punchy, tight powerful low end. The power supply filtering is based on the legendary 67-68 era "12000 series" amps, and this arrangement produces a great combination of punch and touch response. The power section runs on four JJ EL34 which produce well over 100 watts when fully overdriven into saturation. For the service-minded player, an external bias adjustment with low voltage test points (1 per output tube and 1 common ground) allows the user to bias the amp when replacing valves without removing the chassis. Custom options include VariWattage, a switchable X-Gain Mod, True Bypass effects loop (TBFX), passive effects loop, tolex & piping change, and a custom cover with the Granger logo.
