The 2 x 50 watts of this power amp are truly impressive. The four Type 5881 tubes – the original military version of a 6L6 – offer more than enough headroom for every situation. The character of this tube type, rich in overtones, provides an optimal combination of attack, heat and power. With the separate presence controls for each channel, the sound can be tweaked even more individually. Together with the A and B volume controls, two different volumes with different tonal characteristics can be called up. And, of course, it’s all footswitchable. The E840 is the powerhouse every rack needs!
