A must for MESA/Boogie Mark Series


I want a nice dynamic pair of 6L6 for my Mesa Mark 3 . More on the headroom side than compression. Perfect !
The 6L6EH are an awesome match for the Boogie Mark series. Really responsive , punchy , without been overkill in the low-end, sparkling without piercing high-end.
I love them !
Thank you The Tube Store for that perfect match pair.
