So the company that I work for does a huge partership/fundraising thing with the United Way. This year to kick it off, they decided to get a bunch of musicians together from within the company and have a little mini-concert for the employees. Well, there ended up being 3 bands and we had a backline company come in to set up a stage and PA with a drum kit, various amps, etc. I chose to use one of the new Fender Twins that they supplied and just bring my pedal board and guitar. To make a long story short, I was very disappointed in the amp. I thought that the Twins were pretty much the pinnacle of that shimmery Fender clean trademark. I couldn't buy any high end it seemed, and even with the gain setting on about "2" I was still right on the edge of breaking up and distorting. I used the Heritage 535 btw. For what it's worth, I often gig with my little Fender Concert and the Heritage and never have any trouble getting a good crisp sound. To me, there's a point where you can detect the tone of an amp and a guitar respectively and this was certainly the case yesterday too....the amp wasn't working for me. Maybe I got a bad apple or the tubes were old? It was only 3 songs, but I was hoping that it was going to sound ALOT better than it actually did. It was however better than sitting in the office all day.
