Manufacturer's Description from Oldfield

The Marquis 15 blends the unmistakable EL84 tone from the power section with an EF86 preamp to produce a character that is both unique and familiar. The Marquis 15 incorporates many unique features such as power scaling, a 12 way tone selector that allows the player to tailor the brightness of the preamp section to best match the instrument being used and a serial effects loop. This amplifier is well suited for most styles of music including Country, Jazz, Blues and Rock.


This amplifier utilizes all hand wired vacuum tube circuitry and the best quality components available for guitar amplification to produce amazing tone.  It is built to last a lifetime and give the owner countless hours of enjoyment whether on stage, in the studio, or in the home.
