Yeah I was looking at the madcatz website, which has a link direct to distributers of them in the uk – they’re official rb2 add on’s mate – they won’t work with rb1 drumsets though – so hope you have the rb2 set! I think there’s a 3 symbol and 2 symbol add on….not seen the 3 symbol one anywhere in the uk
Google madcatz mate and then from there you can find the link (sorry can’t view those sites in work)
