A used Electro-Harmonix LPB 2ube dual-tube 2-channel preamp. Bought this one used several years ago, and it arrived with one of the tubes not working. So I swapped in a pair of Groove Tubes and it works great. You can use this on stereo signals to add some sizzle and warmth, or feed one channel into the other for a dual-tube preamp/overdrive. Comes with original power supply, box, and all paperwork including manual.
The power supply is unique to this model -- the plugs are shaped differently and it will not run on a standard 9V pedalboard supply. Also, be advised that this pedal is significantly larger than a regular guitar effects stompbox. Comes with the two groove tubes installed (see the last pic) but it's easy to install any other tubes you like: just remove two small phillips-head screws from the black protective bar, and it comes right off, giving you easy access to the tube sockets.Trying to simplify my rig, so I'm letting this and a number of other pedals go.
