Claim:
1. A stringed musical instrument comprising an apparatus for a fulcrum tremolo, the stringed musical instrument further comprising a body, a neck, a head, the neck extending outwardly from the body to the head, a plurality of strings extending from the body to the head, a nut to form a first critical point for each of the strings, a bridge element forming a second critical point for supporting each of the plurality of strings on the body, a head arrangement for securing the plurality of strings to the head and a tailpiece for securing the plurality of strings to the body, each the plurality of strings operable to be laced under tension for play, each of the plurality of strings placed under tension for play having a pitch, the fulcrum tremolo pivotally mounted on the body for pivotally supporting the plurality of strings, the fulcrum tremolo further comprising a macro-tuner element, the macro-tuner element comprising the tailpiece element for a string, the string comprising one string of the plurality of strings, the macro-tuner element operable to raise and adjust the string to pitch for play, the macro-tuner element further comprising a tuning arrangement variably connected to the body, the tuning arrangement comprising a tuning knob and tuning pin, the tuning knob threadedly connected to the tuning pin, the tuning knob operable to variably position the tuning pin to vary the tension of the string, the apparatus connected to the macro-tuner element, the apparatus further comprising: a lever element, the lever element comprising a free end and a cam-like end, the cam-like end comprising a lever pivot axis, the cam-like end further including a first surface, and a second surface, the first surface generally aligning to the lever pivot axis, the second surface formed larger than the first surface, the second surface extending the cam-like end by the difference between the first surface and the larger second surface to form an offset, the lever element further comprising a first position, the first position comprising the offset generally extending in a first direction, the lever element further comprising a second position, the second position generally comprising the offset extending in a second direction, the lever element operable to variably rotate the offset between the first position and a second position, the string tensioned to a pitch for play: wherein pivoting the lever element to the first position is operable to activate the offset to make bearing contact with the stop portion to position the first ring-like element and, thereby, the tuning knob and tuning pin arrangement, away from the second ring-like element to quickly tension the string to obtain a pitch comprising a first adjustable predetermined tension, wherein pivoting the lever element to the second position is operable to quickly position the first ring-like element, and, thereby, the tuning knob and tuning pin arrangement, adjacent to the second ring-like element to relax the string to obtain a pitch comprising a second adjustable predetermined tension.
