Fully gold plated inside and out! I initially got the amazon basic connectors for the same price, but was disappointed in the tiny burgundy positive label they had. It was also very dirty inside the connector and it wasn’t gold plated through out the connector. These are excellent in quality and have a bright red ban on the connector! You wont be disappointed and beats out Sewell connectors for the price!

Decent, but be careful of frequent use.
Size: 12 Pairs / 24 pcs, Size: 12 Pairs / 24 pcs
The looks are very nice, functional if left alone once assembled. After that I would leave them alone otherwise you risk the main male portion just coming loose of the housing, sound quality is decent, nothing to write home about, but again, not very durable. If they could fix that 1 thing, these would be very good buy and value, the rest of each plug is hefty and well made.

Perfect for guitar wire harnesses.
Size: 6 Colors each 10FT, Style: 22AWG, Size: 6 Colors each 10FT, Style: 22AWG
This is the first time I’ve used this type of wire for building and repairing electric guitars. These 22 AWG stranded silicone insulated wires are perfect for connecting control pots and switches. They are soft, flexible, and the insulation does not burn or melt back when soldering. The wire itself is tinned pure copper and solders with ease. I use a silver bearing solder which requires more heat than standard lead/tin solder. The silicon insulation handles the heat just fine without burning or distorting it. The wire is strong and durable, yet it strips back easily with a standard stripping tool. They are true to the advertised thickness of 22 gauge. I have used both traditional cloth insulated (pull back), and PVC insulated guitar hookup wire in the past. I will be using this silicon wire from now on. It is easy to work with and produces a very clean professional looking result.

Does the Job
Size: 2 Colors each 10FT, Style: 22AWG
Seems decent but is very flimsy if you have to run it through any narrow passages.
