I picked this one up used on REVERB. It is in mint condition with the original box and looks like it was hardly ever used. It still had the original 1.10 firmware which I immediately updated to 1.30 downloaded from Zoom site.

Zoom MS-100BT is a fully digital pedal that is quite different from most the pedal effects I like. Most pedals that I like the most are analog. But this is an everything pedal as it can be the only pedal you need for a gig or when traveling. The Zoom MS-100BT stompbox comes loaded with 100 popular effects and amp models. It does not end there as you can also instantly download more effects and models directly from your iPhone, iPad or iPod Touch using a free app called StompShare (available for download in the Apple App Store) and Bluetooth® technology. These effects usually sold for .99 cents or $1.99, but now are FREE! Zoom has dropped the charge for all the downloads as the pedal is now discontinued. Good for me so I downloaded all of them.

I wanted a pedal to take when traveling. The Zoom MS-100BT can be used as a single effect that you can choose from the over 100 DSP effects or you can create an effects chain with up to SIX effects that you can recall using a patch. Since it is a small pedal this makes it pretty convenient. The downside is that it has a bunch of multi use buttons to navigate, but not a big deal once programmed.

The Zoom MS-100BT was the top tier of the MS line, combining the amp modeling power of the MS-50G with the multi-effects wizardry of the MS-70CDR, in addition to Bluetooth iOS connectivity for editing and updating new presets.

From Zoom:

Dynamics / Filter
Shape and control your sound with these 20 compressors, noise gates, filters, equalizers, and wah effects. Go for the classic tone of the MXR Dynacomp, Aphex PunchFactory, Moog MF101, or Z. Vex Seek-Wah, or craft original effects using the automatic Slow Attack, parametric equalizer, or six-band graphic EQ. You’ll also find talking modulators here, as well as random and comb filtering effects and Zoom’s Noise Reduction (ZNR) algorithm, designed to remove noise during pauses while still maintaining your guitar’s natural tone.

Overdrive / Distortion
The MS-100BT’s 21 boosters, overdrives, fuzzes, and lead guitar sounds include emulations of the BOSS OD-1, DS-1, and Metal Zone, as well as the Fuzz Face, Ibanez TS808, MXR Distortion+, Marshall Guv’nor, Matchless Hot Box, Electro-Harmonix Big Muff, and Pro Co Rat. Our ExtremeDS effect offers the most powerful gain of any distortion effect in the world, and there’s even a simulator that allows your electric guitar to sound like an acoustic.

Amp models
8 of the most realistic amp models ever created, including emulations of the finest tube and solid-state amps from manufacturers like Fender, Marshall, Vox, Two Rock, Diezel, and ENGL.

Modulation / Special effects
29 different modulation and special effects are provided, including phasing, flanging, chorus, pitch shift, tremolo, vibrato, ring modulation, auto-rotary speaker simulation, and autopanning—even an intelligent harmonizer that plays along in key. Also provided are emulations of the Boss CH-1 Super Chorus and CE-1 Chorus Ensemble, and ADA and MXR 117R flangers, as well as off-the-hook effects like MojoRolle, Slicer, BitCrush, and Bomber.

Delay / Reverb
You’ll find 22 mono and stereo delays and reverbs here, including natural-sounding rooms, halls, arenas, plates, springs, and tape delay simulators, all designed to add depth and spaciousness to your sound. The MS-100BT even offers reverse, pitch-shifted, filtered, multi-tap, and self-oscillating delays—everything you need to give your sound realistic depth and dimension.

Features:
The MS-100BT offers a wealth of features that make it easy to dial in the exact sound you want. Programming is simple and straightforward, thanks to a streamlined user interface and backlit LCD screen. Its stereo input jack accepts signal from passive and active guitars, as well as from line-level devices such as electronic keyboards and other effects processors, and its dual line-level output jacks enable you to record the MS-100BT’s many sounds in stereo.

Chaining effects: multiple effects, in any order
The MS-100BT allows you to use up to 6 effects simultaneously. This means that you can create rich, complex sounds within the unit itself instead of having to use multiple pedals.

You can also chain effects together in any order you like—important because an overdriven chorus sounds quite different from a chorused overdrive. Experimentation is the key.

Patch cycling: cycle through effects in any order
The MS-100BT provides 50 areas of memory where you can store your edited and chained multi-effects. These are called patches, and 30 of them are pre-loaded with great effects, which can easily be overwritten if you need extra space.

In addition, you can create a custom list of up to 26 patches for the MS-100BT to cycle through as you step on the foot switch—handy for live gigs or whenever you know that you’ll need to access certain effects in a certain order. This list can easily be reordered or erased at any time.

Tuner: tuning made easy
The MS-100BT has a built-in chromatic tuner that supports all standard guitar tunings—even drop tunings of up to 3 semitones.

When activated, the LCD immediately shows you whether the note you’re playing is sharp, flat, or dead on. You can opt to either bypass the currently selected effect (thus giving you a clean, unaffected sound) when tuning, or to mute the signal altogether, allowing you to tune in silence.

Tap Tempo: channel your inner guitarist with perfect synchronicity
Delays, vibratos, tremolos, phasing, flanging, and filter sweeps are all great ways to add motion to your sound, but they’re even more striking when they occur in tempo with the song you’re playing—a process made easy by the MS-100BT Tap Tempo function.

Tempo can be set in real time by either tapping a knob or the foot switch, providing you with instant synchronicity.

Auto Save: never lose that great edit
The MS-100BT Auto Save function ensures that every edit you make is automatically saved. Edited patches can be named with up to ten characters, numerals or symbols, and can be stored in any memory area, allowing you to place your customized effect wherever it’s most convenient.

Power functions: plenty of power to spare
The MS-100BT runs on just 2 AA batteries—either alkaline or rechargeable NiMH. Alternatively, you can use the optional Zoom AD-16 AC adapter to power it from any standard wall socket. When running on batteries, the MS-100BT powers up automatically when a jack is inserted into its input connector.

Battery life with alkaline batteries is approximately 7 hours during mono operation or 5 hours with stereo operation, even during continuous use.
