Mesa/Boogie's EL-84 / 6BQ5 Russian Duet Tubes
are the little brother tubes to the EL-34
– they're the classic European designed tubes that lead the British invasion!
The Mesa/Boogie EL-84
is tight and aggressive, yet smooth and warm with an amazing chiming mid and top end. It provides a brilliant focus with a frequency response that always brings your guitar to the front of the mix. This Mesa tube is true to its classic roots and is extremely consistent and reliable.
