CELEBRATING 20 YRS! 2002 - 2022! 

"WOW! Truly unparalleled bass tone. My AccuGroove "Inception" Dual Tube preamp is the most unbelievable, sweetest preamp I’ve ever heard! Pretty freaking mind bending!" Greg Bauer 

“Holy S*!t, Wow, D#$n, Good God, Eureka, Amazing, finally a bass preamp with Great EQ. AccuGroove has done it again!” Myron Dove

"The sound is amazingly "thick". The difference from my previous preamp being the depth of the of the tube tone and articulation. A sonic masterpiece!" John Allouise (Watermelon Slim)

"You guys have done it again! The "Inception" Tube Preamp is a dream man...good grief. I love it! It's crazy that it sounds so much better than an SVT; It's insane!" Justin Dean Corgan

”Can't say enough good things abut the “Inception“ Tube Preamp! It’s easy to get different tones w/o having to make major adjustments. Tonal quality for days! My eq on my bass is now set flat. The nuances are amazing! AccuGroove, you guys are fantastic!“ Rick Coakley

"If your not playing the Inception at your gig your cheating yourself out of that studio sound!" Terry G Anderson

Total bliss comes from the careful selection of proper EQ and relentless engineering. Following the goal of studio tone for live applications, the expansive EQ enables you to hear the true sound of your instrument as if you were in a great studio.
Until now, you had to choose between tone or light weight. Light weight usually leads to a lack of tone. Likewise, great tone usually means hauling around a heavy lead-sled. Our design implements 2 balanced 12AX7 tubes that deliver FOUR triode stages for maximum flexibility, saturation and tone!
The Inception is the ultimate "no compromise" lightweight, simple, extremely powerful preamp with crushing tone. This preamp is pure sonic bliss!

They are Hand-Crafted in the US by passionate Musicians! Not mass produced by cheap labor overseas. This means we do not pull a box off the shelf & ship it. These are built to order which takes time.
