American Progress, The Resonant Complex

If when you hear punk rock bass you imagine Mike Dirnt or DeeDee Ramone, it’s time to add another to your list. Stevie J of Milwaukee’s American Progress is a solid, intuitive bass player. You can be sure when he is in the mix, the rhythm section is full and tight. When asked what he brings to the table, Steve says, “Simple - I’m the glue that holds the rhythm and the melody together.”
Stevie J believes there is a time to lay back and drive the song, and there’s a time to flash and stand out - and knowing the difference is critical. In 2022 he was featured in “Breaking and Entering” when they covered the release of his band, American Progress’s debut, the Unprocessed EP. American Progress was also a featured performer on the main stage of Harley Davidson’s Hometown Rally of 2022.
“I had originally installed the bridge on a project bass, but when I experienced problems with the bridge on my main instrument, I decided to swap it out for the KSM Foundation. What a difference! It’s stable, and double-tough. It really is a ‘set and forget’ system, and I never have to worry about losing string height, or intonation. And sustain for days…I think that last note is still ringing!”

“I love these KSM bass bridges! Its a nice hunk of solid bridge awesomeness. They claim to give you 'one solid mass of sustain, tone, and articulation' and that’s exactly what they do. And the clamping bolt system they’ve developed adds an extra sense of security for your tone and intonation.”

Leonardo Lospennato's passion for the ancient art of creating musical instruments is an infatuation that began when he put together his first bass, when he was 16. The sound of a string vibrating for the first time. The magic of creating something out of nothing. The never ending search for beauty, for meaning, for perfection. Being a luthier does not requires much more than that. Nor anything less.

With Our Arms To The Sun

"I recently made a huge upgrade to my Schecter Diamond-J Plus bass. I partnered up with KSM music and added their amazing KSM Foundation Bass bridge. The Diamond-J bass from Schecter was already a beast of an instrument but with this bridge it has been taken to a whole new level. The added resonance and under tones this bridge has brought out of my bass are just awesome. It has also added a level of sustain i have not experienced before. It has a high mass bridge feel without adding a lot of weight to your bass. I recommend the KSM Foundation bridge to anyone who wants to take their bass of any price range to a new level of performance."

It is very important to remember that the song is king… Never play or overplay to the detriment of the song, but rather, enhance it. Make sure to have fun playing! Enjoy what you do and who you do it with.” And most importantly, do it with KSM.

I've compared it with the Leo Quan/Badass, Neuser, Schaller, Hipshot, as well as various OEM bridges, and the Foundation sounds as good or better than all of them that I've tried. I love it!"
