GZ30 Head "Austin Special" Specs:

The GZ30 "Austin Special" head is based on the GZ30 but with much larger Power Transformer and a huge output transformer with optimized primary. Transformers are custom built by Mercury Magnetics for the GZ series of amplifiers.

Voltages are higher, the output transformer has 4 , 8, and 16 ohm speaker outs .

Phase inverter has been redesigned for optimum operation. The power supply has been redesigned for a more modern and versatile sound.

Fuller body tone more highs and lows than the little brother combo amp.

There is a two-position switch on the back of the amp labeled "A" or "B".
In one position, the first pre-amp tube is running in triode mode. In the other position the V1 pre-amp tube is running in dual-triode parallel mode. The difference is subtle, but the option is there!

"The amp is designed to be part of your 'instrument'. Accepts all Pedals very well and I personally recommend the Wampler Faux Reverb pedal.  The wampler reverb pedal combined with the GZ30 creates a 3D sound. Please enjoy the GZ30 Austin Special." - Billy Z
