I received this last week. Sonic Silver Peg by One Control. Tiny pedal (think spectracomp) very nicely built. Modelled on the Ampeg V4.
Through headphones its sounds awesome. Plenty of different sound to go through even though there is just 3 dials. Vol, Tone and Mid. However, it is explained that they work in conjunction with the tone dial on your bass - and they do. At low levels through my barefaced super 12 it's a lovely rich sound. Vol on the pedal down for a clean tone. 10 o'clock for
