I am an experienced electronics guy - with a really nice weller temperature controlled iron and all the trimmings. The components of the board were solderred in, I used typical good practices of cleaning the board thoroughly to remove any dirt or other impurities that can impede solder flow. I used a rosin core solder that has a small amount of flux. The solder flow on the plating board was really lousy and two of the lands lifted up almost immediately when heated - this really ticked me off. As one of the other reviewers indicated, the audio input jack and output jacks are RCA connectors. I dont know a single guitar player that would have am RCA to 1/4 or 1/8" adapter, this is just plainly stupid. I would not recommend this kit.
