The MESA/Boogie EL-84 / 6BQ5 Duet is a European classic and the tube type that led the British invasion. It's tight and aggressive, yet smooth and warm, with an amazing chiming mid and top end. Brilliant focus with a frequency response that always brings your guitar to the front of the mix — this tube set is true to its classic roots and is extremely consistent and reliable.
