Mark, congrats on your new guitar. I heard a Casino in action once and it sounded incredible, a decent choice. I can't really add to much that hasn't already been mentioned, you have some very good info here. I do agree with everything that's been said, the type of material and thickness of a pick does more to the tone than most would ever realize. I'm not formiliar with the scale length of the Casino, but if it's like a 335, then one thing you will notice is that the 1st and 6th strings have a tendency to want to roll off the edges of the finger board. A little practice in developing a different playing technique will help. The reason is, the 335 and Les Paul guitars have a 24 3/4" scale vs. say a Fender Strat which has a 25.5" scale. What this means is it takes less effort to bend strings on the short scale and it takes less string tension to tune the string. Some people use a heavier string on these guitars for that reason also. The heavier string will allow lower action because of the higher tension. The occilation pattern of the string is less and allows for lower action without fret buzz and less prone to rolling off the fingerboard. Heavier strings will increase tone, more resonance. I'm experimenting with my 335 and LP now myself. I'm using 10-46 now but I'm planning on trying a set of 10-52. The reason is what I mentioned ,roll off and tone. I tried a set of 9-46, (light on top /heavy on bottom) on my Strat and could not believe how balanced they sounded. I maintained the ability to bend strings like crazy, kept the sharp piercing tone of the 9's and gained much more bottom end with the heavier bass strings. I was also able to lower the action . So a set of 10-52 (light on top/heavy on bottm) would do much the same on the 335 and LP. It's all about what works and sounds good to you, experiment and have fun. One other thing I'd like to mention is what you use to tune a guitar can make a world of difference also. I'm a ferm believer after years of using a digital tuner and comparing the difference between a strob tuner. They are very expensive but they do work, ask anyone who has changed over. A digital tuner can not come close enough to get it right. Strob tuners are 30 times more accurate and are the only device that can set the intonation properly, a digital can not do it accurate enough. You can hear the difference, they are much faster than a digital. Have you ever heard about the dreaded G string curse, have you experinced the 3rd string tuning that never sounds right, always the first to be out of tune, well the strob will eliminate this problem.
