First, this is from 09/10/2012: Ok folks, I was let down by my (month and a half old) YBA300 at a gig Saturday night (09/08/2012)....early in set #2 I lost volume...I turned to look things over....after checking connections and all for about 30 seconds it came back....this happened two more times before a snap crackle pop and then I had nothing. Grabbed the trusty GK 700RBii out of the trailer and finished the night off with it. Getting ready to call traynor, from what I've heard about their CS, I'll be back in business quick. 09-15-2012: I called the merchant where my wife purchased the amp, and after talking back and forth with him all week, Traynor CS said it sounded like a preamp tube. I am waiting to see if they plan on taking care of it. I felt like since it was only six/seven weeks old I needed to call him instead of Traynor. I'll give him another day to get me fixed up, if not I will call Traynor. In late September I received a preamp tube from Traynor, and replaced it....That did not fix the problem. 10/02/2012: After several emails with CS....They finally agreed to have it shipped to them for repair....no charge to me. 10/22/2012: Received it back. 10/26/2012: Tried it out at a gig.....there was some pretty intense noise that would raise and lower only when I adjusted the volume knob. I unplugged everything and plugged everything exactly the same into my GK 700RBii (No noise and performed flawlessly). This is unacceptable after spending so much on a head, and how could they send it back out when it isn't in perfect working condition? I wanted so much to like this head, in fact I loved it for my first six gigs, now I can't trust this thing....It sure is something paying 1300+ for a head and not being able to to trust it....I have been without it more than I have been with it for the past few months. Yorkville/Traynor CS wasn't as helpful as all the stories I have read on here, aside from one Mr. Keefer...I had to be extremely persistent to get them to ship it without me paying for it....I am hoping to get a replacement or my money back now. I have never been so frustrated with a piece of music equipment in my life! This is my fourth Yorkville/Traynor bass amp/or head that I have owned in the past twelve years, and the first time I have had a problem. So basically I am gigging with my 550 dollar GK 700RBii head, but I have almost 2K in both heads....My problem? The YBA300 is being used as a decorative piece right now! Say a prayer to the bass gods for me!
