1992 Tantrum mountain bike help needed

[Swingmodern]

Hello,
I recently purchased this bike but haven't been able to find out anything about it online. Hoping some of the knowledgeable folks here might have some insight.

It was designed by Jonathon S....; can't read the rest of the last name. Has an AMP rear suspension. TT welded on the BB. Decals designed by Josh Jacobson. Cool logo graphics.

Thanks!

Only online reference I found was a Tantrum Company, founded in 2015, to promote a new rear suspension design.
The founder and designer was named Brian Berthold - Your bike looks a good deal older.
I also saw that Raleigh made a women's bike called a "Tantrum" - Also obviously NOT your bike.

This bike was designed mid 90s by Jonathan Garcia. Based out of Vancouver WA at the time. He designed dozens of successful frames and continues to design today. His company TANTRUM CYCLE DESIGNS pre dates the modern Tantrum Cycles. No retation. All the frames were built by local frame builders. Chris eiglehart, Tom Teasdale, Rob Postma. This frame was called the Fore/Skin. Originally had an Action-Tech front sus fork. I still ride with Jonathan to this day. Amazing bikes. Ahead of their time!
