Part of Bartolini's 2J Squared series, this quad-coil design delivers everything from big, growling series humbucker tones to focused parallel response and clear, articulate split-coil sounds. It's an excellent option for players who want more tonal versatility without changing their bass's existing soapbar pickup format.\u003c\/p\u003e\n  \u003cp\u003eInside each M452J are two inline hum-cancelling coil pairs that can be wired in series, parallel or selected individually. Unlike splitting a conventional humbucker, each configuration remains hum-cancelling. The four-conductor shielded cable supports these wiring options, and an optional switching arrangement makes it easy to access multiple voices.\u003c\/p\u003e\n  \u003cp\u003eThe M452J is available in individually voiced neck (M452J-B) and bridge (M452J-T) versions. Both share the same M4 housing and are designed to complement each other when blended or played separately. Select the position you need, or add one of each for a complete pickup pair. Each pickup is sold individually.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003c!-- BEGIN DIMENSIONS AND CONSTRUCTION --\u003e\n\u003cdiv class=\"container product-description-area-white-grey-border\" style=\"margin-bottom: 16px;\"\u003e\n  \u003cdiv class=\"one-half columns medium-down--one-whole product-description-two-columns\"\u003e\n    \u003ch3\u003eDIMENSIONS \u0026amp; FIT\u003c\/h3\u003e\n    \u003cp\u003e\u003cstrong\u003ePickup shape:\u003c\/strong\u003e M4 soapbar\u003c\/p\u003e\n    \u003cp\u003e\u003cstrong\u003eInstrument:\u003c\/strong\u003e 5-string bass guitar\u003c\/p\u003e\n    \u003cp\u003e\u003cstrong\u003eLength:\u003c\/strong\u003e 4.00\" (101.6mm)\u003c\/p\u003e\n    \u003cp\u003e\u003cstrong\u003eWidth:\u003c\/strong\u003e 1.50\" (38.1mm)\u003c\/p\u003e\n    \u003cp\u003e\u003cstrong\u003eThickness:\u003c\/strong\u003e 0.72–0.82\" (18.3–20.8mm)\u003c\/p\u003e\n    \u003cp\u003e\u003cstrong\u003eAdditional cable clearance:\u003c\/strong\u003e 0.15\" (3.8mm)\u003c\/p\u003e\n    \u003cp\u003e\u003cstrong\u003eMounting:\u003c\/strong\u003e Two-hole pattern, one at the bass end and one at the treble end, for #4 pan-head screws\u003c\/p\u003e\n    \u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0078\/6697\/4298\/files\/Bartolini_Bass_Pickup_M452J_Dimensions_Image.png?v=1792638046\" alt=\"Bartolini M452J M4 soapbar pickup dimensions and two-hole mounting diagram\" style=\"display: block; max-width: 100%; height: auto; margin: 12px auto 6px;\"\u003e\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"one-half columns medium-down--one-whole product-description-two-columns\"\u003e\n    \u003ch3\u003eCONSTRUCTION \u0026amp; WIRING\u003c\/h3\u003e\n    \u003cp\u003e\u003cstrong\u003eSeries:\u003c\/strong\u003e 2J Squared Soapbars\u003c\/p\u003e\n    \u003cp\u003e\u003cstrong\u003eCoils:\u003c\/strong\u003e Quad-coil, dual inline hum-cancelling\u003c\/p\u003e\n    \u003cp\u003e\u003cstrong\u003eMagnets:\u003c\/strong\u003e Ceramic (ferrite)\u003c\/p\u003e\n    \u003cp\u003e\u003cstrong\u003eMagnetic circuit:\u003c\/strong\u003e Two types of carbon steel, brass and copper\u003c\/p\u003e\n    \u003cp\u003e\u003cstrong\u003eWiring:\u003c\/strong\u003e Four-conductor shielded cable with bare drain\u003c\/p\u003e\n    \u003cp\u003e\u003cstrong\u003eConstruction:\u003c\/strong\u003e Internally shielded and sealed\u003c\/p\u003e\n    \u003cp\u003e\u003cstrong\u003eConfigurations:\u003c\/strong\u003e Series, parallel or individual inline coil-pair selection\u003c\/p\u003e\n    \u003cp\u003e\u003cstrong\u003eNoise cancellation:\u003c\/strong\u003e Hum-cancelling in all three configurations\u003c\/p\u003e\n    \u003cp\u003eThe 2J Squared design supports multiple wiring arrangements.
