To preface this, I would like to say that I am a huge John Mayer fan, so some of the stuff I am going to say may sound a little nerdy .. Please don's judge me :)

‍

Background behind the build:

As my second amp build, I decided to go with a John Mayer Two Rock signature, with housing inspired by Steel String Singer #004. It offers one main sound, clean and powerful with a three tube reverb circuit. I chose to build this amp because it is the amp most constantly used by John Mayer ever since its release in around 2005. While other amps have come and gone, this amp, more or less, has stayed in his lineup of amps ever since the Continuum era. I chose this amp for a few other reasons over the other John Mayer amps:

• Clean, extremely high headroom; perfect for that John Mayer sound
• nails the Steel String Singer sound without having 6 tubes
• readily available and tested PCB and documentation
• played by my favorite player
• complicated without being overly complicated
• 25 were ever made (so... yeah Im never getting my hands on an original)

Information about the parts (PCB, components)

For this build, I bought a PCB from The tone geek, a chassis from Taylor from amplified nation, and got most of my parts from Mouser. I will do a more in-depth review of the parts I used, the chassis, and the PCB on my blog post on this topic.

Information about/difficulties with the build

This build very closely follows the circuit of a Dumble steel string singer amplifier with a couple of changes. I also had one major difficulty regarding noise in the amplifier. I will go into detail on my troubleshooting process, along with show you some gut shots of the amp, on my blog post on this topic.

Building the headshell

Because the headshell doesn't affect the tone, I thought I could build it myself and it would't be too hard ... boy was I wrong. This was by far the hardest part of the process. I decided to cover it with teal suede to match the color of the aesthetic of SSS #4, one of Mayer's amps. For more information on this, check out my blog post on this topic.

Final thoughts

Overall, A very fun build that taught me a ton of new practices that I will follow in future amp builds. One thing that I don't like about this amp is how difficult it is to transport it and its 2X12 cab. They are both extremely heavy, and even though it has casters, can be quite hard to get from place to place. You can find some elongated final thoughts, along with some more finished pictures of the amp on my blog post on this topic.
