If you're looking for a pedal to turn your amp into a classic British amp (let's not mince words here - AC30), then you should consider the FETBOX Custom V 7.2 from Studio Daydream Handmade Pedals. It offers two channels - Clean and Gain - with an extra 'High Gain' mode as well. It's built to last (forever) and sounds as you would hope. The Fetbox Custom V7.2 is definitely on my all-time greatest list of Vox-in-Box pedals. 10/10.
