This is exactly what I just did.
I had a bunch of euro, wasn’t getting along with the format: endless buy and sell and lack aesthetic unity. Sold most of it, then got a few 4u R*S panels, and honestly couldn’t be happier with the choice. Its all of the flexibilty I liked about euro, with less choices to distract, more real estate, banana jacks, and honestly it sounds better.
I must mention I went on a brief Buchla forray with a 208c as well, and I prefer the Serge to the Buchla, mostly because of the price, but also, I feel like I like the Serge mindset more.
But with all that said, I’m glad I bought modules and not a panel first. Its easier to test the waters on what you want.
Out of curiosity, on average how much does LW charge for his panels? How long is the wait? Are the majority of the components coming from CGS/Elby custom builds that he is combining?
