I run several preamp pedals into the front end of my Alembic F-1x. I had been using a Eden WTDI for a modern sound, a Sansamp BDDI for a dirt/distortion sound, and now my 3Leaf Enabler is for a primary "clean" sound. All into a high quality tube preamp. Works great, versatile, flexible and doesn't require a road crew to set up.
