I am looking at getting a new amp. My needs, outside of sounding good and work properly, are that it have four channels (clean, a bit of dirt, heavy rock, and metal). I am looking at the Marshall JVM 410, Egnater Tourmaster, and Blackstar's Series One 1046L6. I have played through all three and all have their "voice" and I could most likely get along with any of them. The Blackstar is the most limited in the sense that it shares EQ's with a pair of channels. Any of you fine folks have any opinions and/or experiences with any of these? Any other suggestions? I play all manner of stuff, Police to U2, Sabbath to Ramones, Iron Maiden to Volbeat. Granted I play none of them well. Thanks in advance for y'all's help.
