You use various combinations of these pedals in various songs, but you are not good at tap dancing…or you are just clumsy and have (once or twice) stepped on the ultra tricked out-metalized-distortion pedal for the lead in your one ABBA cover. You have seen the digital effects controllers they use on the big stages, and have secretly yearned for one… even though you may never make the big stage. Enter Thomas Guldmann’s Octa-switch II. Your eight effects plug into the eight effects-loops on the back of this unit (all true-bypass, impedance free, gold relays so you can run any of your pedals, new and old without problem), and then by turning on or off the numbered switches in each of eight DIP Bank switches, you determine which effects you wish to use simultaneously in each Bank. There is a blue LED for every effects loop used and for each Bank (so once you are programmed, when you step on Bank 6 you will see the lights of all the effects you have assigned to Bank 6 and the Bank 6 LED). The Octa-switch II has incorporated a couple new features as well! The ninth switch on the left side of the case is a BYPASS Switch….this allows you to completely bypass all eight pedals and enjoy only the unaffected sound of your amplifier. There are also two External Switching jacks which allow you to use two amplifiers and/or switch channels on those amps. Once you have all the Banks programmed, we recommend placing a piece of scotch or electrical tape over each DIP (….just to protect the switch from accidental switching, damage or floods….like beer). There is a buffered (or not….switchable) Mono input and a stereo Output, and the unit is powered by dual 9v batteries, or by a regulated power supply…like the Big John or the Pro Power (both by Carl Martin). ## Features - Octa-Switch MK3 has two external switching jacks for changing channels on your amp(s), or other operational features. - Please note, the DIP switches are slide type, NOT push down. They are easily operated with a small screwdriver, a pen, or a very small finger. - The Octa-Switch MK3 has stereo outputs as well as the stereo return on Loop 8 (this is a stereo jack with tip-left and ring-right). Since stereo effects like choruses are placed at the end of your effects-chain, we would typically insert them in Loop 8. - Utilize up to eight effects Create custom effects banks Highly-visible LED lights Powered by dual 9 V batteries - There is a blue LED for every effects loop used and for each Bank (so once you are programmed, when you step on Bank 6 you will see the lights of all the effects you have assigned to Bank 6 and the Bank 6 LED). - ›See more product details ## Images ![Carl Martin Octa-Switch MK3 Multi-Effects Looper - Image 1](https://images-na.ssl-images-amazon.com/images/I/4158ICbvpOL.jpg) ![Carl Martin Octa-Switch MK3 Multi-Effects Looper - Image 2](https://images-na.ssl-images-amazon.com/images/I/41KZSEHdIAL.jpg) ![Carl Martin Octa-Switch MK3 Multi-Effects Looper - Image 3](https://images-na.ssl-images-amazon.com/images/I/41CM0u9Ab%2BL.jpg) ![Carl Martin Octa-Switch MK3 Multi-Effects Looper - Image 4](https://images-na.ssl-images-amazon.com/images/I/41BDSmBIhbL.jpg) ![Carl Martin Octa-Switch MK3 Multi-Effects Looper - Image 5](https://images-na.ssl-images-amazon.com/images/I/31Eq%2BgV-QxL.jpg) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pe/products/160679937-carl-martin-octa-switch-mk3-multi-effects-looper](https://www.desertcart.pe/products/160679937-carl-martin-octa-switch-mk3-multi-effects-looper) --- *Product available on Desertcart Peru* *Store origin: PE* *Last updated: 2026-05-06*
