MIG-LR/S Tube Preamp for Transistor Leslies

The MIG-L Leslie Tube Overdrive worked with a real tube. It can be mounted on your Leslie's active crossover circuit board with two screws and four wires.

Due to quality issues on russian surplus tubes available on the market today, the MIG-LR tube preamp is no longer available by KeyboardPartner. But if you happen to get one of these gems, you can make your own MIG-LR by etching a PCB and soldering your own parts.
