We start with a stock  great sounding classic 30 watt Celestion G12H30 70th year Anniversary. We then convert it into a Hellatone by exercising the suspension for 15 hours so when you get it, it has a warmer tone on the very first note. This process gives the Hellatone 30 an even richer low end than it already had. The model 30 has wonderful mids and highs and a beautiful overdrive tone. If you drive it hard, you get a real nice cone break up that sounds fantastic. Large heavy 50 oz magnet!
