Just finished:
Like Push Turn Move and Patch and Tweak, it’s beautifully put together. But there’s an inherent conflict between really showcasing some of the more gorgeous pedal designs and artwork, and including lots of content. This book goes for the latter, which I think was the right decision. But it does whet my appetite for a coffee table book of just really great looking pedal designs with full-page photos though 
More so than with the first two books, I personally learned a lot. I’m not a guitar player, and there are a lot of considerations that I’ve just never had to consider
I feel like I have more context now, from historical and practical angles, about pedal design and usage.
I’ve got a list of ideas for different ways to use effects I already have, and effects I can piece together between Eurorack and Bitwig. And also a shopping list of pedals that I don’t think I can replicate so easily, but hear a lot of potential in online demos. And a couple that have been demystified and now I don’t really feel like I need them.
At this point I kind of hope there isn’t another in this series, because all of these are big heavy expensive (beautiful) books and I will probably not be able to resist any future ones
