    The Frog, guitar Tube Preamp Fx1, built by hand, is based on the 1st two stages of the Fender Dual Showman, using exactly the same tube preamp circuit as the iconic Alembic F2b Preamp. Its unique because it is pounds lighter and fits in a small pedal enclosure that can snuggle up with your other pedals on your pedalboard.  Make sure to read the shipping and special International order notes in the product description!
