Custom 2.X is our all new 20 watt offering, now with many customizable options. Based on the platform of our most-popular product ever, the 22H, C2X is built with all of our usual quality standards but at much smaller quantities. Each Custom 2.X is hand-assembled, here in the USA, one at a time. 

20 watts from 2x EL84

Current lead time is approximately 2 weeks from order.

USA and Canada only, for now. 

Printed circuit board (PCB). This was already well renowned for thickness, durability and our large traces made for easy repair and mods. We have taken that a step further by working with our friends at Epic Amplification on the 2.X board. They've updated and re-routed the circuit board and elevated the DC heaters for quieter operation. Now with through-hole plating too. Standard boards are wave-soldered off-shore. Hand-soldered boards are stuffed and soldered here, hence the up-charge.  

Capacitor upgrade is is a low-cost way to get even greater performance from your amp. As always we use high-quality over-spec'd parts throughout. Manufacturer of upgraded caps can vary according to stock and availability and we will always choose high quality parts.

Transformers have been upgraded too. Our original transformer set was already impressive - offering a lot more iron than our competitors. Now named Lightening and Thunder, we've changed vendors and are building even bigger, more robust transformers in smaller handcrafted runs. Further, you can choose our new premium OT, The Heyboer US Thunder, designed and built in the US.

Cabinet is made from void-free plywood. Because we are now building in smaller quantities we can offer optional color choices. More colors added on a regular basis.

Baffle this is the small part of the cabinet above the control panel where the logo is mounted. This is a cool option because you can create your own look by mismatching the covering of the baffle from the main cabinet. Also, you can send a message with your order and tell us to mount the logo in a different position from the standard center. Fits all of our legacy 20 watt cabinets too. 

Control Panel Acrylic choose from black or white, with more limited-edition options coming down the road.


  • Crunch/Overdrive - Crunch is the standard voicing - same as 22H and also the single channel of 20H and the Atomic 16. Overdrive is the lead channel which made us - and the SLO100 - one of the most sought-after tones in amplifiers.
  • C2.X - This is the new Jet City voice. And update to the original with more modern gain.
  • Top Gain provides thicker, even-higher gain tones on second half of gain control. 

FAT is much like adding a fixed depth - it resides on the main PCB and isn't adjustable. +$9

Output Upgrade Configurations

  • The Stock output board contains the speaker outputs; 2x 8 ohms and 1x 16ohms.
  • Epic Effects loop with variable, rear-mounted Depth control. +$49.

Tube upgrades are available for those who have a preference of brand, as tubes can make a distinct difference in your amp's tone and performance. If you have something specific in mind let us know and we can quote you - likely somewhat higher than the in-stock options which we buy in quantity discount.

Custom 2.X

David Pinckney on 29th Jul 2021

Great amp. Met all my expectations, the delivery was faster than originally stated and Doug was very fast answering questions during the build process. Wouldn’t be shocked if I buy a 2nd one with different mods in the future.

Custom 2.X

Justin Long on 2nd Jul 2021

I own an older 100h from this wonderful company that is Jet City. I always get compliments on my sound and tone, and since I’m an active musician decided I needed an extra head, you know just in case. My 100h hasn’t let me down and still hasn’t so I wanted another Jet City. No more 100 watt but I figured, I love my 100 h and I can have this one custom built let’s do it. And I have absolutely ZERO regrets. This thing sounds as god if not better than my 100 and it looks awesome with the snakeskin covering and white baffle. Same everything as my 100h. It’s going to be my main amp head I’m sure. This thing slays!!!! If you don’t have one and want or need a new amp, don’t hesitate. Get a Jet City custom 2.X you will not be sorry!!! Now i need the money for another one….

Solid build and sound

The best high gain amp

Jimmy Lee on 7th Apr 2021

I received this amp and played for hours non-stop. Channel One gives crisp and punch crunch tone. Very cool for classic rock and blues rock. Channel Two bring out very densed high quality sound. Aggressive but smooth. I have used many other high gain amps in the past, but this instantly became my #1 go-to high gain amp.
