One thing aside from the guitar is, they have REALLY, REALLY good customer service.
I purchased an SX 5 string about 2 weeks before Christmas, but didn't have a chance to really examine it until last week - I decided to send it back because of a few minor issues (the kinds of things that can happen with even the most expensive guitars - shit happens). The owner (Kurt) emailed me back on Sunday night at about 11:30 PM to say, even though I had passed the alotted timeframe for a return, they would accept it and send me a replacement anyway. To me, that's incredible devotion to your customer.
So - QC is really good with them, but on the rare occasion you do recieve a guitar that needs to be returned, there is no hassle whatsoever. Honestly, for me, the customer service component of the purchases I make is hugely important. I want to know that if I have an issue or question, that the company I deal with is approachable, and Rondo definitely is. I will most definitely purchase another guitar from them in the future.
As an aside, both of my band mates have made recent purchases from them and the quality of the instruments have been perfect. No complaints at all. I would recommend them to anyone looking to buy another guitar.
