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.
  • Epic 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.

Epic mod installation - if there's something over at  you would like installed in your new amp, under warranty. Simply order the mod kit from Epic and ask to have it sent here. Tick the $50 box for any mods which are limited to parts on the PCB. Tick the $100 box if the mod includes any switches or knobs which require new holes in the chassis and acrylic.
