Equalisers for sale are listed here

In theory, equalisation is one of the simplest audio tasks. That doesn’t stop there being thousands of EQs to choose from, using hundreds of different approaches to a couple of of basic topologies

The earliest equalisers were used to flatten the frequency response of fixed telephone lines. They were typically  LC (Inductor / Capacitor) equalisers followed by a valve gain make-up stage. They were designed for permanent equalisation and would have a fixed HF boost matched to the line

The advent of equalisation in sound recording and cinema audio playback led to variable equalisers like the legendary Pultec EQP-1A. The development of transistors led to equalisers with more frequency bands and greater flexibility

Cost is a big factor. Cheap EQs can work well but are likely to be limited in flexibility and precision. They are also unlikely to be easy & enjoyable to work with

At the other end of the scale, high-end equalisers like the GML 8200 and Massive Passive offer great flexibility, accuracy & repeatability – at a price

The middle ground is where the price / performance ratio works best
