Unfortunately misinformation strikes again... I am sorry to say.
THE FACTS ARE:
The materials are EXACTLY the same between the models (just that you have more choices with a custom shop model...hence the word CUSTOM shop) The specs are EXACTLY the same on all 3 versions including the Chinese made X Trem. You cannot see or feel the difference. Anybody who claims that the Pros are better than hybrids or the materials are inferior is misinformed or simply bias from reading forums with bad info. The forums are a breeding ground for misinformation. The other day i saw a guy answer another that our trems need no routing at all. Again i had to jump in and tell the truth. (to many forums to police) There is no difference in the metals. The ONLY difference is WHERE and HOW it was made. Its like this... L.A. Machinist ($75 per hr.) or L.A. factory worker ($15 per hour) or in China for the low labor rate. Its as simple as that. I have many customers that love the hybrid series and also have had many say the quality was as expected...very high. I play hybrids on 3/4 of my guitar collection and that should say something right there about quality.
By the way. the Pros lock too, they just haven't updated the site.
Next time you all have a question...ask me please. I work for Kahler and run the parts department and customer service dept. I answer emails hourly and work weekends and holidays just for your questions... Its my job.
