I'm from Salisbury, Wiltshire and I literally got my new Kemper Powerhead yesterday and have had no more than 2 hours with it, fitting it around kids etc. I can thank people on this forum for convincing me to take the plunge!
I got the powerhead and mixed it with an Atomic Reactor passive wedge, playing with a PRS 20th anniversary standard 24 and a Les Paul Classic 60. I play in a funk band and also a rock band, in which I use mainly mid-gain settings, nothing too thrashy.
So far I am very impressed and was actually very surprised that my favourite sounds so far are the clean amps. I've only been through the presets after updating to the latest OS and factory pack and not tried any commercial rigs. The VAB clean 2 sounds beautiful on this set up and there were a few useable metal tones. However, I couldn't really find any nice slightly overdriven sounds - they tended to sound very 'grainy' when diggin in to get breakup, quite unnatural sounding and some of the high gain tones sound quite hissy/harsh. The best are either clean or lots of gain. Remember when saying this I know I need more time with it and need to be able to experiment with settings and even guitar volume pots etc to roll back on some of the higher gain rigs to achieve different sounds. Can anyone suggest any rigs they like for a good overdriven blues tone please and feel free to suggest any others too:)
In general, I am very impressed and know that with more tweaking, research, finding rigs and help from this community I will become even more impressed with this piece of kit!
