Eric Johnson, George Allesandro and Eminence have teamed up once again to reinvent vintage tone. Through a reformulated paper cone and optimized basket design, the 40 watt EJ-1240 offers vintage Alnico tone with tight, punchy lows, nice lower-mid growl, crisp upper-mids, and very controlled, articulate, and open highs.
