I play guitar and bass as well as record a bunch of stuff.
Here's a list of my equipment: - Scarlett Solo DI Box - 3x Leads - Ibanez guitar and bass (2 items) - Fender rumble 25watt bass amp (used for guitar too) - Spare strings for both guitar and bass - chrome slide - capo - hard case for both guitar and bass (2 items) - headphones
software wise i use BIAS FX and REAPER to record and get all my tones.
this stuff gives me all the versatility that i want and need while keeping the physical space used to a minimum (plus it's pretty cheap too)
maybe what might help you is organising it first. then getting the equipment that you'll deffinately use together and selling the rest.
