"Forget the noise-gate... but as a mic pre-amp this thing sounds great."
Verified Customer zZounds has verified that this reviewer made a purchase from us.
I lucked out when I bought this over a year ago because I knew little about mic pre-amps and basically just bought the first thing I found. I've since tried others and keep coming back to the Rolls. I agree with other reviews that say that the noise-gate is useless, but if you just need a solid pre-amp with a little compression, this is a perfect choice.
Came with AC/PS
Ease of Use
It's not intuitive to get dialed in (it's hard to even tell which knob does what from the front panel markings) but just fiddle with the controls until you find the sweet spot. I find it works best with just a little less than -10 dB of compression.
Solid metal case, and no problems in over a year. The knobs are exposed so I wouldn't want to drop it.
This thing is cheap but sounds great!
The Wow Factor
There's nothing sexy about this product, but people with much more expensive equipment than mine ask me what kind of mic I'm using (it's an $80-100 AT-2020). It sounds great through the Rolls pre-amp with just a little compression dialed in.
