Musicality is a key, and I'm a specialist in laying down a deep-pocket, groovy, melodic and solid bass lines you need for a song. I'm here to complete your search for a bassline. I've been professional bassplayer and graduated sound engineer for years, so you can trust me.:)

I can record you bass with vintage or modern tones, with different strings - roundwound, flatwound, different techniques - fingers, pick, slap, muted.

In my studio I use Universal Audio UAD Unison preamps, so I can easily switch from vintage Ampeg to modern Eden amps, classic studio preamps (610B, Avalon, Helios) and compressors (1176, LA2A, Fairchild) and tape machine, that are named the best in the market.
I can read notation, chord charts or learn the song fast by ear. I love to play bass like I'm supporting the song, where musicality is a key. I always listen what a song needs and try to fit in a concept.

I'm official Aguilar, Mayones and Rotosound artist, one of the most sought-after bass players in Poland, won Fryderyk 2021 for Soul, RnB album of the year (polish Grammy award), credited to gold records, diamond record, played with biggest names in my country from pop, to rock and hip-hop.

Usually, I need 2 days to record tracks. I work till you will be fully satisfied!

Mayones Jabba Custom 4 & 5 (P-Bass and J-Bass), Fender Jazz Bass 62' CIJ, Epiphone Allen Woody, Aria 5120 1970' Hollowbody, BC Acoustic Fretless, Moog SubPhatty, Boss OC-2, UA Apollo Twin X with a lot of UAD plugins, Beyerdynamic DT770 pro, Craft Ears CIEM.

  11. Review by Rhymes with Otis Music

    I'm fortunate to know dozens of excellent bassists from years of recording and touring, but I can honestly say Adam is the only bassist I'll ever hire again. He's that good: insane musicality, utter professionalism, and the best attitude anywhere. If you're looking for a bassist for your next project, drop everything and hire Adam right now. I'm serious. You won't be sorry. I couldn't be more grateful to have found and had the chance to work with him.

    Another stellar experience with Adam, who is just brilliant. I can't imagine ever hiring anyone else again. Adam is one in a million.

  17. Review by See See Beats

    Adam is a very talented bass player. He put the necessary groove into our project. I look forward to working together again!

  18. Review by Rhymes with Otis Music

    Adam is the best! I've been fortunate to work with a lot of outstanding bassists over a long music career, and I can honestly say that Adam is as good as it gets. Incredible chops, a ridiculously deep pocket, and true musicality are just the beginning. He's also a total pro and a great guy. I can be very particular about what I want, and Adam worked until he got it exactly right. I can't wait to work with him more. If you're looking for the right bassist for your project, stop your search here.
