Interesting he wanted the Marshall for LS, to me the Blue channel on the EL34 is very old school Marshall sounding. I love mine, took me a while to dial a sound I liked on the blue channel though.. I notice the Iconic there too, I recently traded for one of those and quite enjoying it as well, definitely a different beast than the 5150III EL34 but a fantastic amp as well, the clean channel on it can definitely get that Fender chime sound which was very unexpected but a pleasant surprise. Great review! I turned mine up to 3 once in the house... once ;) In regards to the noise, I'm using a TC Electronics Sentry through the effects loop and it work great!
