Hi I have a problem with my Beatle bass... It's a short scale that should be strung with flats... the kind of strings I can't buy in my city! I found D'Addario Chromes Medium scale... is this a good replacement, and should I cut them short? One more thing, what gauge should I go for... since I play in Eb tuning! Will 50-70-85-105 do the job? It's a bit urgent, since I broke the last set of PYRAMID's Thank you!!!
