I’ve recently purchased a Gbfans sound chip. Im just looking for any advice really on the best way to go from here regards what boards to purchase,& also gun light kits that would be compatible with said board. Thanks in advance guys & gals

If you don’t know to solder I would follow that thread exactly.
I used that schematic and materials with some perf board and and solder instead of the proto board and hot glue.
I’m also only using one of the speakers to keep within 8 ohms and it is plenty loud.
You will need a bread board etc to put the chip in. I take it as location England as in the uk. If so I have a spare breadboard you can have just cover postage charges. As for lights any kit will work. I used JT94 pack lights and Jupiter electronics light kit for the thrower. Wiring the chip up is really easy if you take your time and use the guide. You will also need some DPDT switches for sound and lights to work together as the chip uses one power voltage and the lights a different one.
