wtf is hiding inside the baddest bass head in the entire galaxy? I have no damn clue. But this is what’s 'hiding' under the clear lid of our FLow500. This is the beauty you’ll really want to stick it into (the cable from your bass, obviously 😎).

It’s not just another boring bass preamp - this thing is a total Swiss Army knife for bass players. All-analog guts, no digital bu****it. Bluetooth, built-in Li-Po battery, and three separate 9V outs to power your pedals. DI and Line outs with their own volume controls. A headphone amp that actually sounds killer. 3-band EQ. Made for jamming, studio sessions, rehearsals, and gigs. Built-in analog cab sim. Hitting our e-shop real soon.

After long months of tweaking and a bunch of development rounds, we’ve finally wrapped up the FLow bass preamp. It’s built for home practice, studio sessions, and live gigs. A handful of our bassist friends put it through its paces on both small and big stages all over Europe. After the final successful studio test at SINUS Records, we’re finally ready to kick off small-batch production.
Big thanks also go to the wetter bass— FLow wouldn’t exist without them. Catch you on April 25–26 at Poland Guitar Fest, where you’ll be able to try FLow for yourself.

…and that’s a wrap. This is the very last ROD500 ever made, ready to ship. No more coming. Ever.
Well… not exactly. 😏 We just need some time to rework a few things — mainly because some parts are getting hard to find.
Plus, we’ve got a few other projects to finish up first.
So yeah, jokes aside — stay tuned and start saving up 💸
You’re gonna like what’s coming. 😉🔥

This is the third prototype of FLow we’re developing with . (This time, we’ve added an adjustable HPF.) We’re one step closer to the final product. Because we want to, because we can, because we know how. Stay tuned! 💚
