The Lightkeeper is an all-tube preamp based on the clean channel of the Dumble Overdrive Special "High Plate" design. 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, which takes a classic Fender circuit to the next level. The Lightkeeper makes a great pedal platform and delivers the ‘tube feel’ to any ampless setup. It is an excellent choice for those running it directly to a power amp or fx-return. Connecting the Lightkeeper to the front of the amp is also an option, but the result will significantly depend on the internal preamp of your amplifier.
