Inspired by some of history's most iconic British amps (and a couple of unmatched boutique ones) the Mojotone NC3015 is one of our most unique and articulate amps yet. Based on a familiar Class A EL84 platform, this amp delivers tones that salute some of the greatest guitarists of all time. Whether you're looking for the shimmering highs of George Harrison or Brian May, the jangle and chime of Mike Campbell, or the vintage crunch of bands like The Kinks, the careful design and component choice of the NC3015 will not leave you wanting.

The jumping off point for the NC3015 was the tone stack/preamp section of a classic Mid 60s 30-Watt EL84 AC type amp married with a 15-Watt power amp- hence the name NC3015, We felt this would give players the tonal control they wanted and the power amp saturation they desired without being too loud for most applications.


The NC3015 utilizes two EL84 power tubes and three 12AX7 preamp tubes –delivering 15 Watts of classic EL84/AC tone reminiscent of the famed glassy British sound without being too harsh or sterile. We chose an EZ81 tube rectifier for slight compression at higher SPLs.For our kit, we chose our Mojotone BV-30V 60W speaker to complete the British vibe. It has a nice smooth tone at lower volumes and breaks up beautifully as you increase the amp's volume.

Enjoy the balanced sound and ease of use of the normal channel (high and low inputs with single volume control), or switch to the top boost channel for a slightly more aggressive sound with additional tone controls (high and low inputs with volume, treble, and bass controls). The amp also features a "top cut" control that works with both channels to give you a variety of sonic profiles to work with. We excluded tremolo and reverb in this kit as we wanted to provide a straight up, easy to build, easy to use amp that has great EL84 AC Type tones.

Building a fully functional amplifier kit is not an easy task. Before building a kit, one should have the ability to properly solder as well as read and understand a schematic and wiring diagram. While we do our very best to ensure all documentation is current, the included documentation is meant to serve as an overall guide to building the amplifier. Simply following the schematic and wiring diagram does not guarantee you will have a fully functional amplifier. In fact, post build troubleshooting is a common issue across all builds.


Our staff is available to assist with basic troubleshooting needs. There are plenty of online videos available that are helpful with most post build issues. Technical staff is available via email by sending a message to You may also call our sales team to discuss build problems, dial 800-927-6656 and press 1 for sales.


Building a tube amplifier takes time, dedication, resources and most importantly... Skills! The experience of building an amp can come with some frustration, the reward of completing the build is definitely well worth your time. Please review the wiring diagram, schematic and manual (if applicable) prior to making your purchase. Mojotone will not accept any returns on amplifier kits and/or parts that have been assembled, soldered or modified.

Happy Camper.

by William -

I could not be happier with how this amp sounds.Add to that the excellent service after the sale.There were some voltage discrepancies between my amp and the schematic and Andy went above and beyond to resolve the issues.

Great sounding amp and an easy build

by Tom Arbogast -

The amp went together without a hitch. I made a couple of small modifications to the grounding scheme, but the rest is one for one with the layout diagram and schematic.

It sounds great! Highly recommended!
