The two owners were Marc Neumannand Dave Garrett. They were an interesting company. There's a website at www.plush-amps.com, which covers their sister company.Plush became Earth after they moved to California and Earth bought theremains of what was left in the NYC factories. They never actually had their own factory, butrather used various subcontractorsaround the NY/Long Island area. Mostly copied were Fenders (for thePlush lines), or Peaveys (that most Earth tolex amps resembled). Theyactually used Peavey schematics in the shop for service ! The biggestproblem was, they copied Peavey, but used inferior output transistors.Sad part was, that everything else was equal (or in some cases better)than the Peavey counterparts, but the outputs failing hurt them as manyamps came back for service or repairs. They used a high-grade militarysubcontractor (Qualtrol Electronics in Deer Park), who built vendingmachines, and military aircraft electronics for the metalwork and circuitboards that were copied from Peavey, and duplicated very accurately. Peaveywas planning to sue them. Peavy flew one of Earth's technicians toMississippi to interview him about the whole process, but the endresult was to change the models to newdesigns (Peavey's attorneys advised), as it would be cheaper than suing Earth.

They changed the name and did business under ISC Audio of Huntington, NY. They soon went under, and eventually Marc started importing under the "Tour" brand name, which were foreign made (Japanese?)solid state amps, that blew up and caught fire, and he went out ofbusiness pretty quickly." Citation
