Positive Grid AD Clean Amp is available under the Clean amp group and is inspired by the AD 30 from Orange.
According to the Orange Amps30 WATTS OF BRITISH CHIME
The AD30 really is a one-stop shop for all shades of pure British chime and crunch. Every retro, Class A tone you need is right here, thanks to four EL84s, a GZ34 (5AR4) valve rectifier and a pair of 2-stage channels, each providing a different flavour of no-nonsense Orange tone. Whether you’re looking for shimmering cleans, edge-of-breakup jangle or fire-spitting classic crunch, the AD30 has it all in a simple, road-proven package.
