Up for sale is the F-Stop from Milkman Sound. This is a fantastic-sounding dual reverb and tremolo pedal. It nails the sound of classic spring reverb and 1960s-style pulsating tremolo, with independent switches for each effect. In my opinion, it sounds significantly clearer, more authentic, and warmer compared to the Strymon Flint. The unit is in superb condition (see pics). It includes the original box and instructions. It has lived in a smoke-free home and, as always, will be packed and shipped with care.

Let me know if you have any questions, and thanks for looking!

Description from Milkman:

The F-Stop brings two effects found in vintage American tube amplifiers into one pedal. The combination of a tube-driven spring reverb with pulsating "bias" tremolo was first introduced in the early 1960s and has become a standard sound for guitar players and other instrumentalists ever since.

The F-Stop has been designed to bring classic tube amplifier effects into a small package that runs off of a 9VDC pedal power supply. Internally, the F-Stop has 18V of headroom so it can live as comfortably at the end of your signal chain as it does at the beginning. The spring portion of the pedal is digital, but the guitar signal path and tremolo circuit are 100% analog. 

The sound of bias tremolo and spring reverb is unmistakable, and the F-Stop uses modern electronics to achieve an authentic recreation of these effects with similar circuit topography as found in tube amplifiers.
