I know you guys will like to hear this with me being new to this..i ordered the service books to the rockola,507 and 444..hope to get a answer on a stepper in those books

No worries i hope to figure it out seems that a rockoka 444 is not popular for wall boxes

That does help.....do you know what stepper works for them to combine

hello im new to the site,,this is my 1st post..but i do have a rockola 444 and a 507 as well ..what stepper did you use?..thanks trevor
