With all these high recommendations, I had to investigate these Joyo pedals. I have just popped down to Fairdeal Music in Brum & grabbed an ACTONE & an AMERICAN Sound pedal. They are branded in Fairdeal as 'Rocktronics' pedals, but are exactly the same thing from the same factory. I had a demo through a Fender Bassman amp, so it was not exactly the correct set-up to get the full-benefit, being coloured by the Bassman's tone. However you could tell the difference when the pedal was kicked in. I haven't had a chance to try them at home yet, but I will do a test through a PA & possibly a wedge Monitor too in a few days to get the full flavour of the pedals. Certainly, you do get a jangle-tastic clean rhythm tone with the gain set low & the mids backed off. I play mainly Rhythm guitar with my friends & it is general '60s pop, & not just Shads, so I have great hope for these being very useable pedals. We generally put our guitars into the PA with a bit of modelled amp & effects in front, so these can potentially be ideal, rather than lugging actual heavy amp combos around.
