UPDATE: 10/19/2025
I've been laying low for the last couple years working on getting a knee replacement and getting healthy. Also looking to slow down and enjoy life as I near retirement! I'll be taking on mod work again once I'm healed up, most likely after the first of the year. Because I have a steady fulltime gig the FJA Mods stuff happens as I have time, typically on weekends. Please understand due to having a regular job emails might not get answered right away. During the week my time is very limited.

Many of my old mods are no longer available. Shoot me an email to find out if I'm still doing them. I'm sticking to my most popular and less involved mods since time is so limited for me these days in the shop. The big jobs just take too much time and most people don't want to wait that long. I'd rather not have those jobs hanging over my head. Many prices haven't been updated in 15 years so they're not all current. I'm in the process of updating the site as time allows.

Thanks for the many years of support!
Jerry

🎙️ATTN VOCALISTS 🎙️I’m helping put the word out for a new project looking for a badass singer to join the mix!

The vibe is heavy active rock in the vein of Sevendust, Three Days Grace, Five Finger Death Punch.

STRONG live singing is the most important factor, scream and stage presence are a plus!

MUST HAVE EXPERIENCE and be able to tour!

If this sounds like you or someone you know, email [email protected] with videos or links to some of your work 🎤

- the pic in the post is just for inspiration! this is not my band so don’t dm me your submissions, just send the email 🥳
