As Versatile As You Need to Be
The MS-3’s highly flexible design gives you the freedom to create any kind of effects system, from simple to complex. It can serve as a general-purpose effects unit to augment core tone from three stompboxes, or function as the central hub of an advanced hybrid rig with MIDI gear and channel-switching amps. It even works as a standalone effects processor, making it perfect for fly dates and other times you need to travel light. And if you’re just starting out, the MS-3 provides a solid effects foundation that can be expanded as your experience grows.

Three Loops for Your Choice of Effects
Via the MS-3’s audio loops, you can connect three different effects devices to the system. You’ll probably want to hook up your favorite drive and booster pedals to the loops, but you can use any effects you like. Once your pedals are connected, you’re able to switch the loops on/off individually, and position the MS-3’s onboard effects around them any way you want.

World-Class BOSS Effects Engine
To complement the three external loops, the MS-3 is equipped 112 effects types to choose from. They’re organized in six categories, which are available simultaneously: FX1, FX2, Mod1, Mod2, Delay, and Reverb. FX1 and FX2 contain many different types, from overdrives and distortions to compressors, pitch shifters, Slow Gear, and many others. Mod1 and Mod2 offer the famous BOSS chorus and vibrato effects, plus tremolo, flanger, phaser, and more. All the effects are fantastic for guitar, and there’s also a large selection specially optimized for bass.

Big Creativity in a Tiny Package
The MS-3 is packed with decades of BOSS compact pedal and multi-effects know-how, and offers an ultra-efficient design that lets you dial in inspiring sounds right away. There’s a backlit LCD that clearly shows patch/bank numbers and parameters, plus quick-access knobs for editing and status indicators for all loops and effects. And with 200 patch locations, you have ample memory for storing effects and control setups for instant recall.

Complete Foot Control
The MS-3’s heavy-duty footswitches give you easy command of the entire system. In Memory mode, the footswitches allow you to select patches

BUY IT ASAP, it will create space on your pedalboard where less qualified effects are taking up precious space. While you're placing the order, ADD DUMLOP'S COOL NEW Dual Duty VOLUME X, volume/expression pedal. You won't regret these fabulous upgrades!

Great small compact solution
What is your opinion of this product?
I really love this pedal and it is currently the center of my pedal board for bass and guitar. The drive are surprisingly usable and mods are great. I wish I could chose which fx blocks i wanted to use instead of having two of each type. No spillover when switching from preset to preset. Other than that the unit is a great bang for buck solution!

Great little unit that packs a punch
What is your opinion of this product?
Easy to program and it is a small footprint for your pedalboard. Being able to integrate your favorite OD pedals is great! I use loop 3 for the 4 cable method with my Orange Rockerverb. I'm using two expression pedals. One for for volume the other for controlling parameters such as delay effect and feedback levels, modulation speed and depth. Works great and my club board is much smaller and easier to schlep.
