solos.

this tube will give you more compression and distortion
at lower levels than other 6550 tubes.
6550WE tubes are great for bass amplifiers such as
Amperex SVT's. The slight boost in the midrange
frequencies, makes it great for lead guitar solos.

octal type used in the output stages of high-fidelity
