Elevate your vintage Marshall or similar British amp with our renowned Olde 800 Ultra Mod service. Available directly on our website, this service upgrades and modifies your entire amp circuit to match the iconic Fargen Olde 800 MK3 design, featuring our exclusive 3-way “Decade Switch.”

Say goodbye to the harsh and thin stock amp tone – our modification delivers creamy lead guitar sustain and rich tones that transform your amp’s sound. Along with these premium upgrades, we also provide a thorough cleaning, service, and minor repairs, all included in a flat rate.

Once your Fargen Hot Mod is complete, you’ll enjoy the quality and tone of a classic Fargen Custom Shop Amplifier at a fraction of the cost of a new amp. Step up to the ultimate British amp tone and book your mod appointment today.

Experience the superior sound and craftsmanship of Fargen Custom Shop – your vintage amp will never be the same.
