Blockhead amplifiers are faithful recreations of the most sought after Marshall™ "Plexi" amps of the 1960's. Handcrafted from the finest modern and vintage components, Blockhead amps are exact replicas built to identical specification as the originals. Many guitar amplifier makers of the 1960's strived for and advertised their products as having distortion free volume. This was very far from the truth. Thankfully. But this was just the start of all the "mistakes" that went into developing these legendary amps. Over the past few years, this has presented us with the challenge of recreating only the "right" mistakes. Also, many of the original Marshall™ amplifier's were constructed of materials that were immediately available at "low cost" and resulted in many one-time purchases of components. By the time the next materials purchase was made, substitutions had to be worked into designs. This created a large degree of variation in component quality between amps made just days apart. When finally wired and tuned up, these amps had different B+ voltages, output impedance, capacitance, and of course, tone. These points are absolutely critical when searching for the ultimate vintage tone machine. Even more so when finding the "perfect" one. It has taken us years..

Next came the painstaking (we loved every minute) task of blueprinting the transformers and back engineering these prize amplifiers for duplication. Each component was individually selected from various trials and comparisons to best reach our goal of cloning the original. Ultimately, only the best components available today (including Allen Bradley, Bourns, Clarostat, Belden, Rel-Cap, McMurdo, & Ohmite) made it into our amps. If it was not available in production grade, we had it custom made.

No other amp available today is as authentic in sound and construction of the original mid 1960's Marshall™ "Plexi" amps as Blockhead amplifiers. If you want an amp that REALLY does sound like the recording artists or recordings that made these amps famous.. Start checking the museums, record label studios, and Billy Gibbons' house.
