I purchased the Allpart Switchcraft EP0055 Jack because I had bought an old electric guitar which had been lying in a ceiling for twenty years. Of course the electric gear had corroded and was not in a usable condition.
Having paid 2,95? I didn't expect anything.
The jack was easy to install. The solding and everything was done fast, too.
Even though I use the old guitar regularly on stage, this relatively cheap jack doesn't become loose nor gives any kind of unwanted noise. In my next projects I will use this one again because of those reasons.
A good jack for a good price.
