This method of convolution of the sound is nowadays utilised in "profiling" amps like the ones made by Kemper. There are these particular amps, effects, speakers, and/or their specific combos, which are considered sacred/sweet/holy which are highly sought after. But most of them cost a lot. There's also the problem faced by touring bands where they have to lug around huge setups. And then there's the issue of maintenance and repairs. These profiling amps help musicians capture the sound of their favorite setups and replicate it in a compact setup. Hugely popular, if not for the price. There are still purists who swear by the sound of 'analog' setups, but for most of the purposes the sound is identical. Fascinating stuff.
