Modded 1970s Marshall Artiste 2048 with 2X12 & U47

Vintage modded Marshall Artiste 2048 captured with a Neumann U47 positioned at the cone edge of a Marshall 2x12 cabinet. This very cool unknown origin mod replaced the second input with a "gain" knob on the clean channel. Likely similar to the "Artiste-to-Plexi" mod from the build blog linked below. I captured this gain knob at various settings (25% 50% 75% and 100%) with the channel eq flat and volume at 5. Chain: Artiste w/ gain mod => Marshall 2x12 => Neumann U47 => API 1608 mic pre. Recorded at Dimension 70 in New York City.
