Honestly I have to say the Waves 'color' EQs (API, SSL etc.) are generally terrible. Painfully thin and digital sounding compared to any outboard, Nebula and even Duende.
I'm glad to finally be free of the Waves SSL pack.
I agree on the API and V-Series stuff. The SSL I don't mind but I use it in SMALL doses. The Duende CS I have not tried yet... shall do ASAP! =D
