I have had my ROM FX PRO now for 2 years and it is awsome the best IMHO , one of the differeances with the PRO over the CLASSIC Rom FX is you can have 3 fx sounds operated by 3 micro switches that could be mounted in the lid or behind the chest plate anyware really where you can press them , aswell as the great static burst modes , i think John who makes the boards is a top bloke very helpfull , ROM FX ROCK ON
