The SOS29 ’Bass Pi’ pack contains 40 captures of the EHX Bass Big Muff in each of the ToneX, NAM Standard and NAM Nano formats. (Full details above.)
 
All captures of the pedal are in it’s ‘normal’ mode and there are 9 gain settings with 6 different tone increments for each.
 
EHX say that the pedal is, ‘designed to deliver distortion with no low-end loss!The Electro-Harmonix Bass Big Muff Pi is a distortion pedal that gives bass players that great distortion that the Big Muff is known for with no loss of low end.’ 
 
We should also point out that it works great on guitar as well!
