Stumbled on this Russian made overdrive on tinternet, hardly any info on it... Just this vid Took  a punt on it, arrived today ( only took 5 weeks to get here 😄).. Quite impressed It sounds great, good quality and small. Its quite a unique sounding overdrive very coloured (in a great way). If I had to compare it to anything then maybe boss odb ish at a push? ..... But way clearer and more meaty. I haven't a clue what the telephone/service connector on the back is for?!? Any
