{"product_id":"zoom-b1x-four-bass-multi-effects-processor-with-expression-pedal","title":"Zoom B1X FOUR Bass Multi-Effects Processor with Expression Pedal","description":"\u003cp\u003eThe B1X FOUR is the expression pedal version of Zoom's B1 FOUR bass multi-effects pedal. Everything the standard model does is here, plus a treadle you can assign to volume, wah, delay or pitch, so a parameter moves with your foot instead of sitting fixed for the whole song.\u003c\/p\u003e \u003ch3\u003eEffects and amp models\u003c\/h3\u003e \u003cp\u003eThere are more than 70 effects and amp models on board. The effects side runs to over 60 traditional and boutique bass sounds, including octaver, bass synth and fuzz, and up to five of them can run at once in a chain. Nine amp and cabinet emulations sit alongside for recreating an on-stage rig. Fifty user patch slots hold your own chains, which means a set list can be stepped through in order rather than rebuilt between songs.\u003c\/p\u003e \u003ch3\u003ePractice tools built in\u003c\/h3\u003e \u003cp\u003eA drum machine with 68 rhythm patterns in 4\/4, 3\/4 and other time signatures gives you something to lock to, and the looper lets you lay down a part and play over it. For a bass player working alone at home, that pairing covers most of what a practice session needs without another box on the floor.\u003c\/p\u003e \u003ch3\u003eGuitar Lab and ongoing updates\u003c\/h3\u003e \u003cp\u003eZOOM Guitar Lab is the free companion software for the B1 FOUR series. It downloads additional effects, builds and edits patches on a larger screen, and backs the whole library up. Zoom has kept adding to it, with BitCrush released in February 2026 and DynaDelay in April 2026, so the pedal on the shelf today holds more than the one that first shipped.\u003c\/p\u003e \u003ch3\u003eConnections and power\u003c\/h3\u003e \u003cp\u003eA standard mono jack takes the bass in and a stereo mini AUX input lets you play along with a phone or media player. Conversion is 24-bit with 128x oversampling at 44.1 kHz and internal processing is 32-bit. Power comes from 4 AA batteries, rated at around 18 hours of continuous use on alkalines with the backlight off, or from the ZOOM AD-16 9V DC adapter. The USB port is Micro-B.\u003c\/p\u003e","brand":"Zoom","offers":[{"title":"Default Title","offer_id":49101172113664,"sku":"B1X-FOUR","price":146.79,"currency_code":"SGD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0611\/0871\/5776\/files\/zoom-b1x-four-01.jpg?v=1785436037","url":"https:\/\/musicshop.sg\/products\/zoom-b1x-four-bass-multi-effects-processor-with-expression-pedal","provider":"Musicshop","version":"1.0","type":"link"}
