Compressors e.g., DBX 160. Just buy a decent tube amp
Costly DI e.g., REDDI. Just buy a decent tube amp
Class-D tube-emulating heads e.g., WD-800. Just..........
Nothing wrong with any of the gear, in fact each of the above were bloody lovely, but I defo bought them with a sense of 'I need to get this" rather than "I actually need this". Although tongue in cheek, the 'Just buy a decent tube amp' thing is not so far from the truth as since switching to tube amps only I never feel the need for any of them 👍
