About the Jet City JCA2112RC amp:

The Jet City RCA2112RC is combo version of the JCA20H or JCA12S. It is a single channel, 20-watt combo powered by 3 x ECC83, 2 x ECC81 and 2 x EL84. Featuring a simple approach with just one channel and three-band EQ.

Designed by Mike Soldano the Jet City range strives to make beautiful valve tone more affordable.

Owners of this amp like to experiment with a whole range of different combinations of preamp valves. We have found over the years that this is the best combination but you may like to experiment too. Go to the forums to find out more.

It also has a Presence control for tone shaping with a Gain and a Volume to deliver all the punch the JCA20H has. In addition, a valve-driven reverb allows for room reverbs almost all the way to full ambience. Everything is sent through a single Jet City custom Eminence 12” speaker rated at 100 RMS.

Easy access speaker connectors on the rear panel allow the Jet City RCA2112RC to drive external cabinets. So you can do this either with or without the internal Jet City Eminence Custom driver.

Stacked on an additional JCA12S, the speaker volume doubles and the added height brings the controls to arm’s length when you’re on stage.
