I own a Jackson Randy Rhoads RX10D Electric Guitar. Last time I tried a guitar of my friend (don't remember which guitar :/), it required much less strength to do bendings and his guitar was more dried than mine! Also, because of the dry, the bendings have rasped his wood, unlike mine.
This costs me a lot of speed. I think it's the Floyd Rose. Does someone has any idea??
Ohh, and I use standard E tuning with this gauge of strings:
Your friend may have lighter string or a shorter scale length, of say 24.75 vs the 25.5" on your Jackson. In this case you would have more tension, thus more difficult bends.
Out of curiosity, how many springs are in your trem cavity?
