One the respective Product Information Pages for  Big-Nine-0 &amp; Tele Bridge BlasterThe Big-Nine-0 (Bridge Blaster) work best with A 500k VOLUME pot.  The Big-Nine-0 (Tele Bridge Blaster) is similar to a P-90 in several ways, same slam dunk wall-of-sound attack, same high output level attack.  The main difference is it does not have quite the juicy bloom/sizzle of a P-90 Hx.  The following is for the Big-Nine-0 page ONLY. But on the other hand, when playing a mini chord on the wound strings the sound holds together and does not turn mushy (even under heavy pick attack).  The P-90, Hx has a tendency to blurr (turn slightly mushy).  All other P-90's turn mushy in a BIG way, the P-90 Hx is far superior to them in this regard and the Big-Nine-0 is better again.
