Just in at Tone Chasers Music is this Electro-Harmonix Linear Stereo Booster-2 in very good condition. Tested, functional, and as pictured.
This piece comes from a remarkable collection of new old stock Electro-Harmonix items we uncovered in November 2025.
The collection originated from the estate of an early Electro-Harmonix dealer who operated a repair shop in Saginaw, Michigan, about 2 hours from our store. When he closed his shop in the early 1970s, these items were carefully stored away in a climate-controlled environment, where they remained untouched for over 50 years.
We acquired these effects exactly as they were left—still housed in their original shipping box, complete with all original packaging and paperwork. A true time capsule from the dawn of effects.
Each unit has been carefully tested and serviced (including cleaning of pots and switches where needed) by our staff, ensuring they are fully functional and ready for their next chapter.
