Thanks guys, that's very helpful! Hopefully Hohner will be able to either send me some, or confirm if they're both M3's that I need and what length they are. Do any of you on here have a Steinberger/Hohner? I absolutely love mine, but sometimes get frustrated with the way it's balanced - like the low end of the fretboard feels miles away unless I tilt it almost like an upright bass! Anybody tried modding theirs with a homemade strap extension? I'm thinking of trying it out, as I can't find anywhere to get an original one.
