First i like to say i had the original techmaster peb disc but i wanted to get this one for the additional 4 tracks and i was not disappointed =) This is the best Bass disc on the market and if you think your subs can handle the bass just try track 6. Bassgasm =) and my personal favorite computer love =) by the way i have had about 60 bass discs and this is the BEST no contest =) Good going Techmaster P.E.B. keep up the work and lets do some more like computer love and bassgasm =)
