He makes some amazing reverbs, especially the VintageVerb, I think it’s brilliant, and it’s $50, I use that a lot. Actually, that’s the main reverb on all of the records we’ve talked about. It’s just a really good sounding reverb” (Interview with mix engineer David Wrench)
Source assessment of ValhallaDSP as a whole
