ZOOM pedal effect hacking resources

PEDAL EFFECT HACKING RESOURCES
last updated 2025/05/21

Hey y'all! This is a "compilation point" I'm putting up where I'll try to have any necessary resources for ZOOM multi-FX effect "hacking" (effect model interchange from/to other similar devices) available and as up to date as I can.

WHAT APP SHOULD I USE?

NOW, SIMPLER THAN EVER. Just use Zoom Effect Manager for any of these models:

MS-50G
MS-60B
MS-70CDR
G1on
G1Xon
B1on
B1Xon
G1on-AK
G1Xon-K
G1 Four
G1X Four
B1 Four
B1X Four
A1 Four
A1X Four

So, both the G/MultiStomp/on models and the Four models are supported by a single (brilliant!) tool now (since 2025-MAY-16). Not only you can add/remove effects from/to any model of the same generation, but you can even flash the whole firmware from another model to convert it, given hardware is the same. I've done it and it works like a charm, my MS-60B is now an MS-50G, 6 effect slots and all (also have tested MS-70CDR firmware in it no problem).

Finally, here's my ultra condensed "hybrid" bass/guitar FX selections (.zem files for Zoom Effect Manager) for the devices I own, either with their own firmware or with any other firmware ZEM could let me install on them; it literally can convert a device to another model as long as hardware is the same. My effect selections are oriented at having all you'd need for guitar AND bass in one device. DYN/FILTER/AMP/CAB/DRIVE categories are denser while I've kept the MOD/SFX/REV/DLY categories more minimalistic (simply out of my pure taste and needs).

B1Xfour/G1Xfour: 111 effects @100% memory

B1on/G1on: 164 effects @100% memory

B1Xon/G1Xon: 163 effects @100% memory

MS-50G: 177 effects @100% memory

MS-60B: 182 effects @100% memory

MS-70CDR: 181 effects @100% memory

(not affiliated in any way, just sharing some tools that have served me well)

Zoom Effect Manager (awesome ESSENTIAL app for everything MultiStomp, G1/B1on/Xon or G1/B1/A1four/Xfour)

Zoom ZT2 (for all your B3n, G3n, B1four/Xfour, G1four/Xfour, A1four/Xfour and G5n effect hacking needs, now also with partial support for newer Multistomp+ models)

Zoom FX modding (a step beyond I haven't explored -yet-)

ZOOM Firmware Editor (the project that started it all, AFAIK)

Zoom pedal fun (another great compilation site @GitHub, more exhaustive and advanced than this one, yet probably messier to start from)

Some more resources...

Zoom Effect Manager 2.2.0 Windows/64bit (local download, released 2025-05-16)

Zoom ZT2 GUI standalone Windows/64bit .EXE build (local download, built 2022-12-07, ≈26MB, sorry)

Individual ZDL files (just in case you want to "curate" your own firmware with the Firmware Editor)

Individual ZD2 files (newer generation format, necessary for installing FX via Zoom ZT2)

ZOOMIDO-UTILS I'm working on a set of Python based patch manipulation scripts using functions compiled from here. So far they can backup, restore, copy and swap patches on MS-50G/MS-60B/MS-70CDR/G1XON/B1XON/B3 (tested, will also test G3 soon), amongst other simple stuff like switching to a certain patch number, activate/deactivate the tuner or ask for currently selected patch number. I've been forever frustrated with the lack of a proper editor/librarian that will support devices with custom firmware. But thing is I don't even need an editor, I don't intend to edit patches on a PC app. I just needed the parts necessary to backup/restore/copy/move/swap my patches, in a real raw way, and most important, "blind" to the model vs. installed effects matter. It should work with G1ON/B1ON/G3/G3X. Still, USE AT YOUR OWN RISK, my utility scripts are not capable of bricking your device, but they can sure mess with your patches if you screw up the params.

Some more ZOOM relatef stuff...

THANKS EVERYONE for your attention, hope this helps some of you folks out there
