Backstory: Been playing guitar for about a decade now and recently switched over to Bass Guitar for the convenience of not having to carry so much stuff. Bought this product SOLELY for that purpose. I originally bought the VT bass DI pedal but didn't like it. I had heard from a couple friends that the RBI was the way to go and WOW were they right. This thing is AMAZING. The tones that come out of this thing sound 90% similar to a full rig setup. Granted, you would need a good PA +subwoofer at a live venue to really get the most out of this thing, but it works FANTASTIC for DI recording.My rehearsal space has a sub-par PA and it still sounds really really good on there.

    Top Tier Bass Tone
  

*by Z***K on Reviewed in the United States on May 31, 2021*

It’s not often the case that you can buy a top tier item for a music equipment category for such a cheap price. This is what pros use in studios, and it’s only $325. I missed my opportunity on getting an Aphex Aural Exciter for $350, which is also a top tier item for its category, and now they don’t make them anymore. Don’t miss out.

    Delivery was the only issue.
  

*by J***L on Reviewed in the United States on May 21, 2022*

The preamp rocks. But has damage from delivery there were holes in the box where the amp broke through. Cosmetic damage from not enough protection in the OEM box. I am not returning it as it works well and I need it for a multiple gig tour. We all know in the end these end up with dings and scratches anyway. I bought it to replace an old Randall preamp that just gave up the ghost. I like this unit. Many options in sound. I now can just input direct from my bass as the onboard preamp is no longer needed. I'm running this preamp through 2 peavey cs800 amps 1993 model biamped into 2 peavey 1516s speakers 1988 models updated blackwidows with (1)15" and  (2) 8"  with alisis midiverb effects.
