hi folks/ just got my SF-2 from lothar (music-station) in germany and it was really nice to plug this long-awaited apparatus in. how sweet it was...!!!!incredible!!!!the possibilities were stellar! BUT when i turned the volume up a terrible current-hum...well, not creeped up but rather jump violently on me & my speaker...just using my F-1X+gallien-kreuger amp is dead silent...how come the SF-2 is producing this noise? any tips well be welcome! thanx!
It's not entirely clear, but do you have the SF-2 plugged into the effects loop? If so, try cabling like this:
F-1X --> SF-2 --> GK amp
Let me know how it works out.
Also try isolating each piece so that none of the components are touching each other. Probably not it, but worth a try just to see.
I'm wondering, would incorrect voltage jumpers do this??
1000 gracie for your advice. well...i was sent info on how to place the jumpers on the (god, it?s good!) F-1X (we have 230V in sweden so i used the 220v stance). the SF-2 is juiced by the adapter that came in the package. on other rigs (inferior ones) this hum is not unusual. it?s sometimes taken care of by holding on to it/grounding. not very practical while playing!
have a nice weekend good folks!
everything sounded good at the gig - i was oversensitive...worse was my new epifani-cabinet were i discovered that one element in my 4x10UL wasn?t attached/screwed into the cabinet. and buzzing and trying to pop out.......pretty embarrasing for epifani!
