Check this out: I call it the Cola Crusher rig (because of the black/red color schemes on both amp and bass). -P-bass/flats (Modded Nate Mendel (PU's/Bridge/Cover) with GHS P Flats) -Fender Koil Kord (HIGHLY RECOMMEND THEM) -Ibanez p3110 -Ibanez p210kc SOUND/REVIEW: I bought it because I really digged the low-mid focused boxyness of the p3110 but found it lacking true rumblin' low-end (because of size). That's why I decided on buying the extension. Result: EXACTLY what I wanted! Extended bottom, still low-mid focused (and ofc more volume if needed ).
