Re: Looking for experienced advice on Bogner Shiva or Hughes & Kettner Duotone
Just to clarify here, Bogner did release an EL-84 Shiva, however, it is a very rare amp. The EL-34 is what you're looking for if you want your cleans to stay clean (which I would imagine is what you're looking for for reggae). The overdrive is great on its own (doesn't really need a pedal unless you're looking to do really high gain stuff). What I really like about the Shiva is that it sounds great at lower volumes thanks to the well designed master volume. Obviously, to really enjoy what the amp has to offer you want to get those tubes cooking a little bit and it does open up as you turn it up, but at low volumes, it does surprisingly well.
I also owned a Hughes & Kettner Triamp at one point (it has two channels that comprised the Duotone - Channels 1a and 3b). The cleans are good if you have a humbucker guitar, but are lacking if you like single coils because the clean channel is a bit on the thin side (although it is sparkly and articulate). The overdrive is a bit thinner than the Bogner, but it's more aggressive (it can do high gain without any pedals). The Duotone, like the Triamp needs to be pushed to give up the goods, but it sounds decent at lower volumes.
