UPGRADES
There are several elements inside the FATSO which were designed to be “modifiable”. Empirical Labs
may release information and hardware options that will allow owners to alter the curves and other
important performance parameters of their FATSO. Most of these modifiable elements will not improve
the performance, but will offer other very cool compressor variations. It may be possible for user to safely
modify the FATSO and create unique sets of curves and filter options. The UBK FATSO is an example of simple
compressor modifications. Check our Website from time to time for news: www.EmpiricalLabs.com
Attempting to modify or make adjustments to your FATSO may void warranty unless you have approval
from Empirical Labs. There are a number of critical adjustments that cannot be made properly without the
calibration tools we have here at the factory. Any sign of internal adjustment by the user will void your
warranty with the exception of changing the fuses or line voltage selection.
Empirical Labs Inc. takes no
responsibility for the safety of anyone opening the FATSO for any reason. There are dangerous voltages
present when unit is plugged in. Refer unit to properly qualified service center or return to factory.
