I am the original owner of a gently used DTAR Solstice. I used this to blend the two pickups (K&K Bass Max and Double Big Twin) on my old Kay. I've also used it to mix sources on acoustic guitar. I haven't used this in several years so I'm selling it. Works great and is in excellent condition. Comes with case.
The power adapter once fell a couple of feet onto a hard surface and was split open. It cracked along the seam so I just put it back together and taped the two halves. Works fine. Of course a new adapter could be purchased.
Any questions, please ask!
