Tubesteader's nod to the Dumble Overdrive Special!
The Lightkeeper V2 is an all-tube preamp based on the clean channel of the famed Dumble Overdrive Special.
This preamp is all about bright clarity and articulation!
It's got a vintage Fender vibe but with tighter bass and more prominent mids, thanks to the Dumble-refined tone stack.
The Lightkeeper works exceptionally well as an overdrive or preamp and will fit nicely on any board.
Additionally, it is well-suited to live at the end of your chain. Send it into your favorite cab sim or IR loader for responsive feel and dynamic tone thanks to the onboard 12AX7 tube!
