Mr Dumble..TwoRocks are extremely close tonally and feel wise. I could easily fool you with clips of the Emmy and the Dumble, my Sig V1 and Dumble, my Custom and Dumble,
The sound and feel you you experience when going between different amps might feel similar to you but I guarantee you they WILL!! feel different to me..
To others it might not even matter!!.. I am not doubting your word that to you they might feel or sound the same.. however to pass that judgement on to me or others is rather presumptuous don't you think..Iv'e seen you play and you play nothing like me!!
You are one man with one opinion and one man might know his tone but no one man knows the tone of another..What he feels hears and experiences and is inspired or emotionally moved when playing through a fine musical instrument is one of a very personal experience..This I am passionate about!!.. I am glad you have amps that inspire you and consider VERY GOOD..That's what it's all about..
Good Luck!!
Tony
