I visited the showroom yesterday, me and my friend, we were considering taking some lessons (Guitar and Piano). Shady took us in a tour to see the showroom and take a look at the instruments they have in there, meanwhile we got to watch a little girl learning Piano :) As Shady has explained, the lessons are always one-on-one, given by certified teachers.
In regards to the instruments, we have seen some of the best brands, when it comes to guitars (loved them!), there are Takamine, Manuel Rodriguez, Cordoba, Dean guitars, and Luna, all displayed in a very nice way.
Drums on the other hand, were all Pearl Drums, one of the world's finest brands. I'm no expert in the equipment, however during the tour Shady showed us Line 6, Avid Pro Tools and Mbox, which I took pictures of, for those who are more experienced to check out :)
One more thing caught my attention was the books arranged on stands in the reception area, collection of books that vary between composing music books, and books about learning how to play different instruments..
