This used 3rd Power Clean Sink MK II 1X12 Combo is in Excellent condition with minor signs of handling and use.  Looks like new.  Sounds really nice.

The Clean Sink is essentially the larger 3rd Power Kitchen Sink model in a compact 1x12 combo design.  Around 20 watts with 6V6 power tubes. It gives you American and AC voices with a blend control, plus a switch for AC Normal vs Top Boost behavior.  More focused than the Kitchen Sink, and also easier to carry and easier to use as a dedicated clean platform. It’s especially attractive if you want Fender clarity and Vox chime without the Plexi side of the bigger Kitchen Sink amp.

FROM 3RD POWER:

At the foundation of 3rd Power is a simple idea: the electric guitar speaks through three essential voices.

• American Clarity:  Open, dimensional, articulate.
• British Chime:  Harmonic, responsive, alive.
• British Crunch:  Authority, drive, impact.
  

3rd Power was built to honor these classic languages of tone — while rethinking how they can live together in modern instruments made for real players.

Big, open, piano-like cleans with depth, dimension, and headroom. 
This is your foundation tone — articulate, dynamic, and alive under your hands.  Full low-end without flub.  Bell-like top end without harshness. Touch-sensitive response.  Clean that feels as good as it sounds.
