I have a Grace 101 mic preamp for sale, comes with the power adapter. It has an amazing clean detailed sound, I'm downsizing my gear so it's up for sale.
Great for recording, I've recorded whole albums with this mic preamp, when you start stacking tracks you can really hear the 101's clarity and detailed sound, each track has its own space and it doesn't get muddy, makes any mic/guitar/bass sound as it truly should. This is definitely a step up from Mackie or lower priced channel strips and mixers. It competes with API's and other high end mic pre's.
The front lettering is wearing off a little bit and the chrome is peeling a tiny bit to the right of the gain knob, other than that it makes anything sound awesome through it. Both XLR and 1/4" inputs/outputs.
