Basement-Lab Arena Stack — Filtered Marshall Wall

Tom Scholz’s early Boston sound used a Les Paul into a fully driven Marshall, load-box attenuation, fixed-wah-style midrange filtering, EQ and extensive layered recording. Barry Goudreau recalled turning the Marshall all the way up and finding the sound with the wah and midrange setting; exact song controls were not preserved, so the values below are approximated from that documented method.

Notes

Build width with tightly played layers and a small detune rather than excessive reverb. The fixed filter should emphasize the singing upper mids without becoming a nasal cocked-wah caricature.

Don't have this gear?

See the same signal chain mapped to another platform. Knob values carry over as starting points — gain ranges differ between platforms.
