For all Niteshade Amplifiers dating from early-mid 2010 and older:
This update includes the following:
1] All audio circuit applicable updates
2] All power supply updates
Upgrades include new circuits where applicable, different power supply configuration and a test for optimal low-noise grounding and modification if necessary. Parts and labor are included.
The standard upgrade is only $150.00. If you have an amp that is 2-5 years old or older, possibly more can be done to it and the price may be different. The best thing to do is to contact me with a photo of your amp. Some early amps may not require updates- it depends on where they were in a R&D cycle and the model.
