The Taurus TM-2 requires some soldering so a sufficient soldering iron, 60\/40 Rosin Core solder, black &amp; red wire of appropriate gauge (if needed), heat shrink tubing, Digital Multimeter, and a good pair of small diagonal cutting pliers is a good idea to have on hand or source from a friend. <\/p>\n<p align=\"center\"><img style=\"background-image: none; border-right-width: 0px; padding-left: 0px; padding-right: 0px; display: inline; border-top-width: 0px; border-bottom-width: 0px; border-left-width: 0px; padding-top: 0px\" title=\"Taurus_TM-2_Preamp_html_m6ee6ec36\" border=\"0\" alt=\"Taurus_TM-2_Preamp_html_m6ee6ec36\" src=\"https:\/\/www.bestbassgear.com\/ebass\/wp-content\/uploads\/2013\/02\/Taurus_TM-2_Preamp_html_m6ee6ec36.jpg\" width=\"500\" height=\"287\"><\/p>\n<p>We start by carefully removing the control plate and pick guard on this particular Jazz bass, and place the screws for re-install in a safe location. I choose to place the screws inside a piece of cellophane from a cigarette pack and seal it shut to prevent them from being lost.<\/p>\n<p align=\"center\"><img style=\"background-image: none; border-right-width: 0px; padding-left: 0px; padding-right: 0px; display: inline; border-top-width: 0px; border-bottom-width: 0px; border-left-width: 0px; padding-top: 0px\" title=\"Taurus_TM-2_Preamp_html_mdc1c3fd\" border=\"0\" alt=\"Taurus_TM-2_Preamp_html_mdc1c3fd\" src=\"https:\/\/www.bestbassgear.com\/ebass\/wp-content\/uploads\/2013\/02\/Taurus_TM-2_Preamp_html_mdc1c3fd.jpg\" width=\"500\" height=\"322\"><\/p>\n<p>The wiring attached to the controls on our control plate is carefully removed using the diagonal cutting pliers and carefully set aside. <\/p>\n<p align=\"center\"><img style=\"background-image: none; border-right-width: 0px; padding-left: 0px; padding-right: 0px; display: inline; border-top-width: 0px; border-bottom-width: 0px; border-left-width: 0px; padding-top: 0px\" title=\"Taurus_TM-2_Preamp_html_4fc29ded\" border=\"0\" alt=\"Taurus_TM-2_Preamp_html_4fc29ded\" src=\"https:\/\/www.bestbassgear.com\/ebass\/wp-content\/uploads\/2013\/02\/Taurus_TM-2_Preamp_html_4fc29ded.jpg\" width=\"500\" height=\"375\"><\/p>\n<p>Fitment is going to be tight for this particular installation since this Jazz bass does not have a battery box. To aid in fitment and allow the use of 4-controls on a Jazz bass control plate the output jack had to be relocated out the side. To prevent any further alterations to the exterior body the decision to mount the battery hidden under the pick guard was chosen. I chose the following location and made the decision to remove enough material here to recess the battery low enough to be concealed under the pick guard.<\/p>\n<p align=\"center\"><img style=\"background-image: none; border-right-width: 0px; padding-left: 0px; padding-right: 0px; display: inline; border-top-width: 0px; border-bottom-width: 0px; border-left-width: 0px; padding-top: 0px\" title=\"Taurus_TM-2_Preamp_html_2a3f1072\" border=\"0\" alt=\"Taurus_TM-2_Preamp_html_2a3f1072\" src=\"https:\/\/www.bestbassgear.com\/ebass\/wp-content\/uploads\/2013\/02\/Taurus_TM-2_Preamp_html_2a3f1072.jpg\" width=\"500\" height=\"297\"><\/p>\n<p>Now that our battery location and jack situation have been sorted out we can begin by removing the controls from control plate. Set aside the controls for future use if you choose to go back to your original control configuration or just to serve as backups if something ever fails. <\/p>\n<p align=\"center\"><img style=\"background-image: none; border-right-width: 0px; padding-left: 0px; padding-right: 0px; display: inline; border-top-width: 0px; border-bottom-width: 0px; border-left-width: 0px; padding-top: 0px\" title=\"Taurus_TM-2_Preamp_html_3935f3ec\" border=\"0\" alt=\"Taurus_TM-2_Preamp_html_3935f3ec\" src=\"https:\/\/www.bestbassgear.com\/ebass\/wp-content\/uploads\/2013\/02\/Taurus_TM-2_Preamp_html_3935f3ec.jpg\" width=\"500\" height=\"375\"><\/p>\n<p>We now begin a basic test fit to ensure that the controls once mounted to the control plate will fit in the top routed control cavity.  <\/p>\n<p>The controls from Left to Right are:  <\/p>\n<ul>\n<li>Master Volume Push\/Pull Active Passive\n<li>Blend\n<li>Treble\n<li>Bass<\/li>\n<\/ul>\n<p align=\"center\"><img style=\"background-image: none; border-right-width: 0px; padding-left: 0px; padding-right: 0px; display: inline; border-top-width: 0px; border-bottom-width: 0px; border-left-width: 0px; padding-top: 0px\" title=\"Taurus_TM-2_Preamp_html_58b01d8d\" border=\"0\" alt=\"Taurus_TM-2_Preamp_html_58b01d8d\" src=\"https:\/\/www.bestbassgear.com\/ebass\/wp-content\/uploads\/2013\/02\/Taurus_TM-2_Preamp_html_58b01d8d.jpg\" width=\"500\" height=\"375\"><\/p>\n<p>The fit is not exact and does require some removal of material from the control cavity. The modular connector plugs for the ribbon cable, size of the p.c board mounted to the potentiometers, and location of the potentiometer all prevent this from being an easy install. Since this particular bass did not come equipped with a battery box I chose to remove the shelf between the control cavity and the neck pickup. The pick guard covers the modification for the battery location. A Dremel rotary tool with sanding drum cylinders was used to remove the material and prevent any finish chipping with the aid of blue painters tape.  <\/p>\n<p align=\"center\"><img style=\"background-image: none; border-right-width: 0px; padding-left: 0px; padding-right: 0px; display: inline; border-top-width: 0px; border-bottom-width: 0px; border-left-width: 0px; padding-top: 0px\" title=\"Taurus_TM-2_Preamp_html_4285f106\" border=\"0\" alt=\"Taurus_TM-2_Preamp_html_4285f106\" src=\"https:\/\/www.bestbassgear.com\/ebass\/wp-content\/uploads\/2013\/02\/Taurus_TM-2_Preamp_html_4285f106.jpg\" width=\"500\" height=\"375\"><\/p>\n<p>The control plate is bolted and used to scribe the shape onto tape. From here 1\/8\u201d (3mm) into the scribe line is marked every 1cm with a straight edge with the marks orthogonal (90 degrees) to the scribe line.  <\/p>\n<p align=\"center\"><img style=\"background-image: none; border-right-width: 0px; padding-left: 0px; padding-right: 0px; display: inline; border-top-width: 0px; border-bottom-width: 0px; border-left-width: 0px; padding-top: 0px\" title=\"Taurus_TM-2_Preamp_html_m26bba27a\" border=\"0\" alt=\"Taurus_TM-2_Preamp_html_m26bba27a\" src=\"https:\/\/www.bestbassgear.com\/ebass\/wp-content\/uploads\/2013\/02\/Taurus_TM-2_Preamp_html_m26bba27a.jpg\" width=\"500\" height=\"375\"><\/p>\n<p>The material is carefully removed and checked periodically with the controls mounted on the board for fitment. Multiple test fits are required to ensure the smallest amount of material is removed.  <\/p>\n<p align=\"center\"><img style=\"background-image: none; border-right-width: 0px; padding-left: 0px; padding-right: 0px; display: inline; border-top-width: 0px; border-bottom-width: 0px; border-left-width: 0px; padding-top: 0px\" title=\"Taurus_TM-2_Preamp_html_241bfcd8\" border=\"0\" alt=\"Taurus_TM-2_Preamp_html_241bfcd8\" src=\"https:\/\/www.bestbassgear.com\/ebass\/wp-content\/uploads\/2013\/02\/Taurus_TM-2_Preamp_html_241bfcd8.jpg\" width=\"500\" height=\"375\"><\/p>\n<p>The master volume control presents the greatest issue with the screw holes not lining up perfectly with the control plate. More delicate removal of material is handled until the fit and alignment is precise.  <\/p>\n<p>The total amount of material during removal is best emphasized here.  <\/p>\n<p align=\"center\"><img style=\"background-image: none; border-right-width: 0px; padding-left: 0px; padding-right: 0px; display: inline; border-top-width: 0px; border-bottom-width: 0px; border-left-width: 0px; padding-top: 0px\" title=\"Taurus_TM-2_Preamp_html_163d86ff\" border=\"0\" alt=\"Taurus_TM-2_Preamp_html_163d86ff\" src=\"https:\/\/www.bestbassgear.com\/ebass\/wp-content\/uploads\/2013\/02\/Taurus_TM-2_Preamp_html_163d86ff.jpg\" width=\"500\" height=\"375\"><\/p>\n<p>Once fitment is achieved, the cavity is smooth with sandpaper moving up in consistency until it is smooth to the touch and no ridges can be felt. (Please Note: The pickups were removed during all material removal to ensure no damage to any wiring. They were periodically re-fit and left unscrewed to test how the controls fit with wiring).  <\/p>\n<p>The control cavity is shielded to conceal most of the work handled during removal.  <\/p>\n<p align=\"center\"><img style=\"background-image: none; border-right-width: 0px; padding-left: 0px; padding-right: 0px; display: inline; border-top-width: 0px; border-bottom-width: 0px; border-left-width: 0px; padding-top: 0px\" title=\"Taurus_TM-2_Preamp_html_m3fd01f5d\" border=\"0\" alt=\"Taurus_TM-2_Preamp_html_m3fd01f5d\" src=\"https:\/\/www.bestbassgear.com\/ebass\/wp-content\/uploads\/2013\/02\/Taurus_TM-2_Preamp_html_m3fd01f5d.jpg\" width=\"500\" height=\"375\"><\/p>\n<p>All wiring is pre-tinned including the pickup leads, output jack wiring, and battery clip wiring.  <\/p>\n<p align=\"center\"><img style=\"background-image: none; border-right-width: 0px; padding-left: 0px; padding-right: 0px; display: inline; border-top-width: 0px; border-bottom-width: 0px; border-left-width: 0px; padding-top: 0px\" title=\"Taurus_TM-2_Preamp_html_3cef6580\" border=\"0\" alt=\"Taurus_TM-2_Preamp_html_3cef6580\" src=\"https:\/\/www.bestbassgear.com\/ebass\/wp-content\/uploads\/2013\/02\/Taurus_TM-2_Preamp_html_3cef6580.jpg\" width=\"500\" height=\"375\"><\/p>\n<p>From here the soldering is straight forward and the wiring diagram supplied includes all the necessary details. Once we have all the connections soldered we mount them to the control plate and carefully screw them in.  <\/p>\n<p>Final test fit is made and the ground from the control plate and each individual controls to the strings and bridge is tested with a multimeter. The multimeter is a handy tool to diagnose any wiring issues once already assembled should there be any.  <\/p>\n<p align=\"center\"><img style=\"background-image: none; border-right-width: 0px; padding-left: 0px; padding-right: 0px; display: inline; border-top-width: 0px; border-bottom-width: 0px; border-left-width: 0px; padding-top: 0px\" title=\"Taurus_TM-2_Preamp_html_3646b49d\" border=\"0\" alt=\"Taurus_TM-2_Preamp_html_3646b49d\" src=\"https:\/\/www.bestbassgear.com\/ebass\/wp-content\/uploads\/2013\/02\/Taurus_TM-2_Preamp_html_3646b49d.jpg\" width=\"500\" height=\"375\"><\/p>\n<p>At this point it may be a good time to start cleaning the instrument thoroughly, aside from blowing the dust out of everything. I chose to polish and wax the finish on top before installing the pick guard. From here we install the pick guard and continue cleaning until we are at the end. The pickup height is re-set and the instrument tuned before plugging in and finally testing it out. It <strong><em>Works!<\/em><\/strong>  <\/p>\n<p align=\"center\"><img style=\"background-image: none; border-right-width: 0px; padding-left: 0px; padding-right: 0px; display: inline; border-top-width: 0px; border-bottom-width: 0px; border-left-width: 0px; padding-top: 0px\" title=\"Taurus_TM-2_Preamp_html_613a132e\" border=\"0\" alt=\"Taurus_TM-2_Preamp_html_613a132e\" src=\"https:\/\/www.bestbassgear.com\/ebass\/wp-content\/uploads\/2013\/02\/Taurus_TM-2_Preamp_html_613a132e.jpg\" width=\"500\" height=\"375\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>This is a step-through process of installing a Taurus TM-2 preamp.
