This used 3rd Power Kitchen Sink Head & Cab is in Excellent condition with minor signs of handling and use.  Looks like new.  Sounds marvelous.

The Kitchen Sink is aimed at players who want one amp that can cover sparkling clean tones, chimey Vox-like sounds, and British rock crunch to higher-gain lead tones.  About 40 watts using EL34 power tubes.  All-tube spring reverb and an effects loop. 3rd Power emphasizes point-to-point handwired construction and their Hybrid-Master circuit for keeping the feel of the amp while controlling volume.

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.
