Pros
If you are a musician, it will be tough to find a better place to work. The discounts are immensely helpful when it comes to gathering your gear. However, sometimes it is difficult to find a reward in the (often) large amounts of work you are asked to do. The concept is wonderful: Work in an environment where you are able to sell gear to people who need it. Commission makes sense in this workplace; sell a larger item, see a larger reward. However, this is about where the problems start.
Cons
Although as a GC employee you are working in the largest music retail supplier in the US, you are not readily equipped to sell that merchandise, which leads to the misconception that employees are ignorant. This is often not by choice. Without proper training on new items (which of course is supposed to be covered in the online certifications, but this feels more like homework than actual knowledge building), we are often left without an answer when a customer asks about a new piece of gear. This leads to wasted time using the dreadfully slow computer terminals to locate an answer. We are ill equipped, underappreciated, and under compensated.
