The GB-4000, SR-4, and M.O.P.A. are hand assembled in the USA. Our technicians fully test and calibrate your instrument before we ship it to you. We want you be feel confident that your new instrument is built to exacting standards and will last for many years.
We offer a full 2 Year Warranty on parts and labor. If your instrument experiences any issues during the warranty period, we will repair or replace the unit at our discretion. If we determine that full replacement is required we will use either a new or refurbished unit for the warranty replacement at our discretion.
This Warranty covers parts and labor required to bring the unit into full working order. If shipment to the factory is required for warranty repair, the owner is responsible to pay for shipping to our production facility in Utah. The manufacturer pays for FedEx return shipment within the 50 United States. For warranty repair outside the U.S.A, the factory offers discounted return shipping outside the U.S.A.
The only exception to this warranty is the MOPA Vacuum Tube which has a 90 day warranty. If there is an issue with the vacuum tube during the first 90 days, we will replace it.
All refurbished units are tested and upgraded to the most recent equipment specifications before we ship to you. We want you be feel confident that your refurbished instrument will last for many years.

The GB4000 and its companion amplifiers are designed and built to last for years. Even if the unit is outside of the warranty period, almost any issue that comes up can be easily and inexpensively repaired. However, we have seen some instances where a machine is damaged beyond repair by electrical spikes or other catastrophic conditions.
At any time after the warranty has expired, if your GB4000 circuit board cannot be repaired by the factory, we will replace the circuit board and any internal components needed for half the price of a new unit. This 1/2 price replacement guarantee offer applies to all current and previous models of the GB4000. Shipping cost to the factory and return shipping to the customer is paid by the customer.
No other company has the confidence in their equipment to offer this type of replacement guarantee. We stand behind our products and believe in taking care of our customers for life.
