Introduced in spring 2010, the Orange Thunder 30 is an all valve class A 30 watt, twin channel amplifier, powered by four EL84 power valves (two more than the Orange Rocker 30 model). It is available in head and 1 X 12 configurations and includes an F/X loop (not featured on the Rocker 30) and the 1x12 is front loaded.

The Thunder 30 was designed to incorporate the best of the Rocker and Thunder series. The new amps have two channels: the first is a classic vintage channel which has crystal clear clean sound and when turned up delivers a thunderous vintage power amp overdrive. The second overdrive/distortion channel features a shape control like the Thunderverb models to give a British tone crunch.

According to the March 2010 Orange press release:

The Thunder 30 combo offers the perfect balance between power and portability and is ideal for regular gigging. It’s small and light enough to be portable whilst also offering a phenomenal tonal range for use in the studio environment.
