About the Jet City JCA20HV amp:

To begin, the Jet City JCA20HV is a single channel, 20 watts, vintage head. It uses 3 x ECC83 and 2 x EL84, just the same as the regular JCA20H. The difference, however, is this Vintage version has been re-voiced so its cleaner, darker and with an opened up power section. It still has all same great features as the regular version. For example, it uses the same three-band EQ and has mostly “point to point” circuitry.

In addition to re-voicing, the Jet City JCA20HV has a Depth switch, based on Soldano’s famous Depth control, and a post-master effects loop. An effects loop is an essential feature to some guitarists and unlike the regular version, this has one. Finished with the tweed design this amp looks professional and has its place on the stage.


  • Valves/Tubes needed: 3 x ECC83 and 2 x matched EL84.
  • 20 watts of power output.
  • Added effects loop.
  • Tone controls: Bass, Middle, Treble, Presence, Depth.
  • Preamp volume and Master volume.
