Last winter, my desire to acquire a boutique Marshall style amp started to get the best of me. I was looking for something in between an 18 watter and a 50 watter. It also had to have the ability to get some serious crunch without ear bleeding volumes, and an fx loop. After much deliberation and trepidation, I decided to pull the trigger. A couple months ago, I took delivery on my first custom amp - the Category 5 Tempest. The Tempest features two discreet channels - a Volume/Tone channel based on a JTM45/Fender Bassman, and full tone stack Plexi channel with fx loop and footswitchable mid boost. The Plexi channel features the tone stack from Joe Bonamassa's custom Category 5 Plexi. This amp also has Power Scaling and an absolutely killer reverb on both channels. This amp is true Marshall glory. I started laughing when I first plugged in because both channels really do sound like a JTM and Plexi respectively. The JTM channel provides a warmer, cleaner tone than the Plexi channel. It makes a great platform for your overdrive pedals, and also works really well when combined with the Plexi channel. The Plexi channel can really get the grease going when you start getting into the 5-8 range on the volume. The mid boost provides what's described as a Dumble-style midrange. I have played the proverbial D-style amps, and I think the mid boost on the Plexi channel delivers on that claim. I also hear a little Matchless C-30 in this channel. Very harmonically rich. Chords just ring out with all kinds of cool overtones. For me, this amp really shines with single coils. My Strat and Nocaster may have never sounded better. Everything I always wanted my Fenders to be. Thats the thing with this amp. It really brings out the best qualities of your instrument. A Strat sounds like a Strat, a Tele sounds like a Tele, and a Les Paul sounds like a Les Paul. I also have to mention the great service Don at Cat 5 provided. Always attentitive and patient, and he did a great job keeping me up to date on the amps progress. The after sale support has been great too. Keep in mind, this amp didnt exist when we started discussing the details. The platform was there with their 18 watt Tsunami, but I was looking for something with more headroom and an fx loop for one of the channels. From what I understand, this will be a new model in their amp line. These guys are definitley worth checking out.
