Is this a standard standard size?

Yes, it is a standard size US Spec 1/4" jack with 3/8-32 threads and a 3/8" bushing length (the threaded portion of the jack is 3/8" in length), and requires a 3/8" mounting hole. It includes 1 nut and 1 trim washer. Thanks for asking.

Since we are replacing thesein the guitar why not do it in the amp too? Wouldnt the concern be the same?

Certainly. These can be used in amplifiers, speaker cabs, or any application that uses a panel mount jack with solder lugs. Using them to replace circuit board mounted jacks may be a bit of work though, and probably isn't a job for a novice. Also be aware that tube amps can produce potentially lethal voltages. If you aren't 100% sure of what the safety procedures are for any amp part replacement or repair, take the amp to a professional for the work to be done.

Would this work on guitar pedals

This would work for pedals. It's just about the same dimensions as a regular 1/4" jack. It's a bit more expensive, and you'd need two per stompbox. I'd just go with regular jacks myself. This special jack has four total contacts, which makes it beneficial on a guitar, which gets moved and tugged a lot. Stomp boxes just kind of sit there. It's up to you though.

is this metric threaded?

No. It is US Spec 3/8 - 32 threads per inch (same thread as Switchcraft #11L).

Excellent. Don't buy for Active Basses

I bought this thinking I could fit them in my bass guitars which have active preamps... they don't work in them. These are only for Passive instruments. Having said that, the build quality on these is amazing. If you have passive instruments, I highly recommend them.

These are amazing. Swapping out all my old, loose guitar outputs with these. I don't wire the extra contacts, just use them to hold the cable more secure and keep them from wearing out as fast. Makes for a SOLID connection. Highly recommend.

Produit conforme. Le jack de votre guitare sera bien maintenu avec les 4 contacts mais n'atendez pas une amélioration du son ce n'est pas un vrai pure tone.
