As new - Bought a few years ago, but I never had the chance to use it live, other than testing it out at home. Sounded great. I believe you can buy them online (without the lead included) for £171.

This is designed for with Trinity Solo Classic pickup system. This is the unsaddle Pure Mini + the Mic attachment for the guitar sound hole. It's used to blend them perfectly with this preamp and lead.

I believe it is also possible to upgrade your Pure Mini solo unsaddle pickup to the add in the the K&K mic attachment for the guitar sound hole. (You need to buy this separately)

and used this preamp in the same way.
