What is a prototype?

A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:

Proof of Concept

Explorations that test ideas and functionality.

Functional Prototype

Demonstrates the functionality of the final product, but looks different.

Appearance Prototype

Looks like the final product, but is not functional.

Design Prototype

Appearance and function match the final product, but is made with different manufacturing methods.

Production Prototype

Appearance, function, and manufacturing methods match the final product.

About

The Metro-Plex 50 watt head and combo amp is the state of the art evolution of plexi inspired vacuum tube guitar amplifiers.  The tonal heart and soul of this amp is a 1968 Marshall Superlead 100 watt plexi paired with a 1967 basketweave cabinet, loaded with G12M greenback speakers.  The top of the plexi mountain!

Features:

  • 50 watts RMS with 50w/25w switch
  • two foot-switchable channels with independent gain and master volume
  • gain level switches for each channel
  • highly tweaked EQ controls
  • clean boost circuit with gain control and level switch
  • Zero Loss FX Loop with pedal and line level options
  • mid cut switch
  • two button footswitch (channel and boost)

Specs:

  • 21" wide  11" tall  8.25" deep
  • carbon fiber motif
  • 120/240V AC operation switch
  • external bias adjust and terminals

Risks and challenges

Advancing the state of the art requires an obsessive dedication to the craft, that compulsion is present and accounted for. It's helped along by the addition of high end measuring equipment. Specifically, the APx515 audio analyzer. This unit has been a game changer in the pursuit of authentic vintage amp tones. In fact, it has ushered in a completely new approach to achieving those coveted tones.
Conceptualizing this new approach and testing the concept has taken many hours already. Many more resources are still needed to see it fully realized. Getting "in the ballpark" is almost trivial, while truly capturing the tone, vibe, feel, sag, dynamics and harmonics of a great tube amplifier requires dedicated design and critical listening.

Creating and documenting a patent-worthy concept and circuit is no small feat. But this concept must be developed and protected. This requires time and funding. Both are critical and are the catalyst for countless applications and product concepts that may ultimately use this design concept.
