Hi all , I have a blue el34 6100 head and am considering selling and getting an sv20. I have other amps ( 2203 / shiva / mesa royal) for the higher gain sounds and the 6100 lead channel just isn't as great as those amps. So what Im after is an amp that can do the classic hendrix / ac/dc sounds and sv20 seems to be the one. possible cons - it has no master volume , is single channel ( maybe not an issue) , no fx loop-reverb. any thoughts? I do love the clean on the 6100 and channel 2 is ver good , but maybe none of these can quite get what an sv20 can? or is there another amp to be recommended?
