Orange Thunderverb - Clean preset

Close · 74/100 confidence. Most values readable. Minor gaps filled by inference from similar circuits.

The Thunderverb is a two-channel Orange head from the mid-2000s, offered in 50- and 200-watt versions. A relay-switched clean channel and a cascaded dirty channel each have their own ECC83 gain stages and tone stack, the dirty channel ranging from vintage Orange crunch to thick high gain. An ECC81 drives and recovers the spring reverb, a second ECC81 buffers the effects loop, and an ECC83 long-tail-pair inverter has relay-selected masters for each channel.
