After jamming on this all weekend I thought I'd give my impressions. First of all, the tone of this amp ( Sound City ) is most interesting. What's MORE interesting to me is this has become a 'case study' in people's perception of tone. I'm going to get right to it..........this amp does NOT do it for me personally. I find the tone just plain lacking in what I like in an amp. I live on the 'edge of breakup' and this Sound City refuses to go there. She stays clean no matter the volume setting. I've never played an amp such as this. Very, very different. The sensitivity switch in the back cuts the power way down but with zero breakup not sure why it's even an option. I cannot relate to the 50 PLUS on many levels and felt like it affected my playing in many ways and according to what comments were made to me, I guess it did affect my playing . Here's the interesting part to my SoundCity review.............( to me anyway ). While jamming in a rather large home studio to where the SC could be 'cranked' ( and was ) wives, kids, neighbors, etc. AND BANDMATES claimed I have NEVER sounded or played better! WTF ? They said they loved the tone of this amp and will be very angry if I were to sell it. I am dumbfounded as I have always been the go to guy when someone wants an opinion on ToNe! I think I have good ears but now.............:NUTS I don't know anymore. "ToNe" or people's perception of it............................ Whew !
