For me they were a big waste of money. I don't like them , and don't use them, the bottom end is not there, they sound veiled, like a blanket is over them
I'm sorry to say, but I have to agree with kriswylde. Avoid the official Dr. Z profiles altogether. Great company, great amps, and a GREAT guy, but there's not a single profile in that pack I found worth keeping. Thin and dull, every single one of them. YMMV. I went so far as to contact Dr. Z's customer service to politely request a refund — which I've never done with a profile pack and I knew was a long shot — and the rep was kind of snotty with me. Just a real turn-off from a company I respect so much.
I'd be eager to hear the Selah Zee profiles with my gear. The demos sound great (but then again, so did Tone Junkie's official Dr. Z demos...)
