I purchased a used Tech 21 Sansamp Bass Driver pedal from Guitar Center a while ago. The price was at $120, and was wondering why that was the lowest I've seen around. After the purchase, I went to my friend's place, and compared mine to his, which he bought brand new earlier in the year. I noticed that his has 2 more switches. I assume I have an older model. Playing through both of them, the one major thing I noticed is that the newer one is capable of a considerably larger amount of drive. This is compared when I put the drive at 9 o'clock, 12 o'clock, 3 o'clock, and max on both pedals. My question is... Is my the newer version suppose to have more drive than my older version? Or is there a problem with mine? Thanks in advance!
