High end studio microphones like the Sony c-800 , the telefunken U48 , & nuemann U87 , for example .
rack mounted gear like the LA-610 , a Neve1073 , Avalon tube compressor (rack gear can go into the wall or in rack spaces like you had in the tileset). I have tons of picture references.
the list could get long lol so I kept it short . I'd want to give player the options to upgrade their equipment over time and model after real gear
