Either direct or through a speaker cabinet, I was able to get a beautiful, clean sound with unbelievably low noise.

- Jon Herington (Steely Dan)


The Solitaire tucks a quiet, clean and highly engaging

tube instrument amp into a durable hand-sized package, giving electric instrumentalists access to classic tube amp tone and familiar controls for ampless stages and in the studio.


The Solitaire universal tube DI works with any electrified musical instrument, adding the engaging signature of end-to-end vacuum tube amplification to guitar, bass, keyboards, harmonica, fiddle, mandolin, accordion - even vocals. Solitaire's comprehensive connectivity makes it easy to integrate into a wide range of rigs and situations: performance, recording, reamping, practice, etc.


You can choose a standard 'guitar', 'bass' or 'universal' model, or we can work with you to select the ideal tubeset, circuit options, output transformer, capacitors and resistor formulations to match your instruments and needs.
