Just to let you know, a big iron amp used at any volume is technically being used to its potential because the tone at all volumes will be a bit different than lower wattage amps. Big iron amps aren’t just about volume by any means.
That said, the LBX is cool. However, believe it or not the 50w EVH heads perform better at super low volume because all the frequencies fade in at the same rate, where the highs and lows of the LBX fade in with the volume knob at different rates so you have a “minimum” volume before everything starts sounding right. Again the LBX is still overall a cool amp though.
