{"product_id":"carl-martin-octaswitch-mk3-guitar-pedal","title":"Carl Martin OctaSwitch MK3 Guitar Pedal","description":"\u003cp\u003eThe Carl Martin Octa-Switch MK3 features 8 true-bypass relay loops with complete signal isolation for each pedal, delivering transparent tone preservation and silent switching across your entire pedalboard. It offers instant preset switching via hardware-based DIP switch programming, allowing you to engage multiple effects simultaneously with a single footswitch. The unit includes a dedicated global bypass switch to remove all loops instantly, alongside individual LEDs and bank indicators for clear visual status on dark stages. For advanced routing without additional gear, it is equipped with two external switching outputs to handle amp channels or external devices, a switchable input buffer to accommodate various rig setups, and full stereo output support.\u003c\/p\u003e\n\u003cp\u003eWhen Carl Martin designed Octa-Switch MK3 together with Thomas Guldmann, the goal was simple: give players full control over complex pedalboards without tap-dancing, menu diving, or digital abstraction. Carl wanted instant access, absolute reliability, and a signal path that stays transparent no matter which pedals you use.\u003c\/p\u003e\n\u003cp\u003eOcta-Switch MK3 is built around eight true-bypass relay loops. Each of your pedals lives in its own loop, completely isolated when not in use. Using the DIP switches for each bank, we decide exactly which pedals are active in each preset. Step on a single footswitch, and an entire combination of effects engages at once — clean, silent, and repeatable every time.\u003c\/p\u003e\n\u003cp\u003eVisual feedback is immediate. Each active loop has its own LED, and each preset bank is clearly indicated, so we always know exactly what’s happening underfoot — even on dark stages.\u003c\/p\u003e\n\u003cp\u003eTo keep the rig flexible, Carl included a dedicated global Bypass switch. With one press, all eight loops are removed from the signal path, providing the pure, unaffected sound of the amplifier. It’s the fastest possible way to reset the rig mid-song or between sections.\u003c\/p\u003e\n\u003cp\u003eOcta-Switch MK3 also includes two external switching outputs. These can be used to switch amp channels, control multiple amplifiers, or interact with other external devices — making the unit suitable for far more than just pedals.\u003c\/p\u003e\n\u003cp\u003eThe input buffer is switchable, allowing us to run either buffered or unbuffered input depending on cable length, pedal choice, and personal preference. The output is stereo, supporting more advanced rigs without additional routing gear.\u003c\/p\u003e\n\u003cp\u003eProgramming is intentionally hardware-based. Once the DIP switches are set, the presets are fixed, predictable, and immune to accidental changes. For live use, Carl Martin recommend covering the DIP switches after setup — not because it’s fragile, but because reliability matters.\u003c\/p\u003e\n\u003cp\u003eOcta-Switch MK3 is housed in a solid metal enclosure and powered either by batteries or an external regulated power supply. It’s a professional loop switcher built for players who want maximum control with minimum complication.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eProgrammable loop switcher with 8 loops\u003c\/li\u003e\n\u003cli\u003eTrue bypass with buffer option\u003c\/li\u003e\n\u003cli\u003eMIDI-compatible external switching\u003c\/li\u003e\n\u003cli\u003eStore up to 32 presets\u003c\/li\u003e\n\u003cli\u003eSolid metal construction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eDimensions: 311 x 155 x 65 \/ 12.24″ x 6.10″ x 2.56″\u003cbr\u003e\nWeight: 1.6 kg \/ 3.53 lbs\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifi\u003c\/strong\u003e\u003cstrong\u003ecations\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eInput: 500K Ohm (buffer)\u003c\/li\u003e\n\u003cli\u003eOutput: 560K Ohm (buffer)\u003c\/li\u003e\n\u003cli\u003eS\/N Ratio: 70 dB\u003c\/li\u003e\n\u003cli\u003eLoops: 8 pcs. true bypass relay\u003c\/li\u003e\n\u003cli\u003ePresets: 8 pcs via DIP switch\u003c\/li\u003e\n\u003cli\u003eExternal Switch: 2 pcs (latching)\u003c\/li\u003e\n\u003cli\u003ePower consumption: max. 380 mA\u003c\/li\u003e\n\u003cli\u003ePower supply: 9 V DC (regulated), 500 mA minimum, 2.1 mm female plug, center negative (-)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eSupplier warehouse item.\u003c\/strong\u003e Please allow 3 business days handling time before dispatch, subject to supplier availability.\u003c\/p\u003e","brand":"Carl Martin","offers":[{"title":"Default Title","offer_id":46248452948012,"sku":"57345","price":799.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2970\/9956\/files\/octa-switch.jpg?v=1790223244","url":"https:\/\/roycemusic.com.au\/products\/carl-martin-octaswitch-mk3-guitar-pedal","provider":"roycemusic","version":"1.0","type":"link"}
