Upgrading the portafilter, drip tray, and OPV spring enhances the functionality and convenience of the Gaggia Classic Pro.
Installing a PID provides better temperature control and accuracy, resulting in more consistent espresso extraction.
The mod kit for controlling the vibratory pump allows for flow control, giving users the ability to adjust the water pressure for different brewing techniques.
These modifications are not Gaggia Classic Pro-specific and can be applied to other espresso machines with vibratory pumps.
Performing these mods requires some technical skills and knowledge of electrical components. It is important to follow instructions carefully and consult professional help if needed.
