Introducing the Frog Tube Preamp. It is based on the Fender Dual Showman preamp section from the late 60’s and inspired by the iconic 1970’s era Alembic F2b preamp based on the same circuit.

The Frog, guitar Tube Preamp F1a is based on the 1st two stages of the Fender Dual Showman, using exactly the same tube preamp circuit like 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.  These are a few sample builds:
