DO NOT whatever you do let kbaudio touch your amp!!!! it will not come back to you in the shape you send it out in, and their communication sucks.
NO ONE USE KB AUDIO!!! I recently had a terrible experience with them. here is just a short part of mine: had my amp packed VERY securely bubble wrapped, popcorned etc by UPS and then they sent it back in a box 3 times bigger than it needed with very little packing material (why they didn't just use the box I sent it in I will never know) and it looked like Ace Ventura delivered it beaten with a baseball bat.
