I just completed shopping for compressors and though I never tried the Pigtronix I did try a Barber Tonepress, a Wampler ego and MXR Custom Comp to replace the MXR Dyna Comp. I felt the Dyna Comp didn't give enough control of my signal. I like the Wampler the best then the Barber but an emergency Root Canal required me to spend the saved money and I went with my 3rd Choice which was the Custom Comp and I'm very happy with it for the money I spent. The balance between the attack and sensitivity controls gave me the closest operations like Blend controls the the Wampler EGO or Barber Tonepress have.
