"Kevin uses an ABM 500 RC EVO III head with a ABM EVO III 6x10 Cabinet."
“I play a Fender Jazz bass because, since its creation along with the P bass, they’re the basses that all basses have been compared to. My Jazz bass has a simple, straight-to-the-point tone. I’ve had this bass since I really started pursuing music seriously and it’s been a great journey to able to grow with my instrument as a player and have it age with me—it sounds better every day. I play an Ashdown ABM 500 EVO III head with the matching 6x10 Ashdown cabinet. It gives me the clarity I desire, with tons of bottom end to rattle the stage and crowd. I love having the accessibility of pumping a single ECC83-S tube through the head as well. It offers up just enough grit to help me really pump the tone throughout the mix and not use any pedals for boosting or overdrive.”
In a live performance video from Manchester in 2019, Andy Gilmour of Raging Speedhorn is seen using the Ashdown Engineering Ashdown ABM 500 EVO III, which he has relied on for over 20 years.
"[My Evo III] gives a solid warmth for softer, acoustic acts and my own compositions for TV & Film", says producer, composer and session musician Mark J. Adair.
