I have had my Bogner Shiva head for about 3 years now and at times I love the amp and at times, although I dont hate the amp, I think about going in a different direction. I guess in summary, the Shiva does a very good clean and has a very good Overdrive and in that, the Shiva makes a great amp if youre looking at a versatile one amp set-up. I have found that I much prefer Pedals with the Shiva vs. using the actually overdrive channel for lead playing. I like channel 2 for its smooth deep crunch, but at times with humbuckers the crunch tone can get a bit muddied up. If your tonal needs are much stronger in the clean department, (Jazz etc) then you may look elsewhere and the same can be said for overdrive. (Hi Gain etc.) But if you need an amp that will cover lots of different material, then the Shiva may be something to consider. For me, I play everything from Pop/Rock to Classic Rock to Funk to Pop/Country, so trying to find one amp that covers all this is just about impossible at the tonal levels that I want to reach. I never could warm up to modeling amps, although I love some of the sounds, I am always left feeling a bit cold. As Leon has said, and Im paraphrasing here, its not so much the amp as the way you play that is most important, and while this is true, we all look for different tones to appease our pallets and what our own perceptions become as we grow as musicians. I guess I really feel at home with the Fender and Marshall sounds, mostly because my early influences reach deep into those tones. The Aiken Sabre, the VHT Pitbull or the Rivera Fandango all come to mind when I think about replacing the Shiva, but I wonder if I would be any happier in the long run? I have thought about going with a two head set-up, one head for great Fender cleans like a cowtipper head and one head for Marshall type overdriven sounds that could even get into hi-gain territory, even like a Soldano. There are just too many choices out there! Well I better get back to practicing instead of typing because that is more than likely where the truth lies in finding tonal nirvana!
