Hate is perhaps too strong a word, but I bought a Wal back in the early 80s which I thought was awful (Pro 2E). Got rid of it within a month and then, based on recommendations, bought another Wal, this time a Mk1. This was slightly better, but also had to go. Why didn't I like them? So many reasons, but mostly, I found them very finicky to use live and could never get a decent amount of 'bass' from either model. Traded last one to Overwater, and bass and sound were immediately sorted.
