Laney Gh100Ti preset

Verified · 80/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Laney GH100TI is the Tony Iommi signature amplifier head, a 100-watt all-tube design co-developed with Black Sabbath's founding guitarist. It features a dark, massive midrange voicing with tight low-end and high-gain capabilities suited to the heavy riffing style Iommi pioneered. The GH100TI is one of the few factory signature amplifiers to closely replicate the actual stage and studio tones of the endorsing artist.
