How much does rosin change with changes in temperature or humidity? I have a variety of rosins, but have been using Fiddlermans rosin since it came out. For whatever reason (can't remember) I started using other rosins and ended up going back to Jade and was happy with it. Yesterday I noticed a thick layer of rosin on the strings giving off that grey, dull look. I tried to get it off with a wine cork, nylon scratch pad, wood stick and my fingernail. I finally resorted to alcohol which worked. I have been using more rosin lately than I normally use. I can go 3 or 4 days without adding rosin, but lately its everyday. But that could be because I rehaired one bow and the other I am using is new and synthetic hair. I will sort it out, I'm just wondering if you have had any similar experiences.
I reached a similar conclusion about the bow that came with my cheap EV. It was synthetic hair. This was before I purchased my FM Concert and two FM CF bows, but I did have a horse-hair bow belonging to my old Skylark.
With the synth-hair bow that came with it - rosin built up on the EV strings and body - and I was repeatedly re-applying rosin and cleaning-down the strings and asking myself - am I applying too much ? but no - because the synth hair bow would eventually just slip, and glide over the strings... ( I was playing / messing-around a LOT in the beginning ). Finally thought - try the Skylark bow - what a difference !
At about that time, I got the FM Concert, and some weeks later got a second FM CF bow ( because - believe it or not - I dropped the skylark bow on the floor - RIGHT on the tip - and it broke ! It is beyond repair, but I keep it to mess with the "upside-down-bow" playing four notes at a time thing..... (infrequently, and only when I need an excuse to do something insanely crazy...)
Anyway - long story short - I dumped the synthetic hair bow... It will never see the light of day again....
I suspect it has more to do with the synth hair than rosin type, temperature or humidity - of course you can "make it work" - but - WAYYYY too much effort for me to bother with @MrYikes ! LOL
I seriously recommend not copying my mistakes. D'oh -
Please make your own, different mistakes, and help us all learn :-)
I am not good enough to feel a bow's worth while concentrating on the bow, but when I'm concentrating while playing music, it will suddenly occur to me that there is a problem. That happened today with the synthetic hair. I was playing and realized I didn't like the sound so I switched to FM carbon and was happy again. At least now I have tried it and have made my determination about it. All is good.
