The Flamma FX150 is a floor unit from Flamma, listed at 15.5*28.7*8.4 cm and 1.345KG1. Its impulse responses run at a 44.1 kHz sample rate1. The jack layout around the unit covers an AUX IN (1*1/8" unbalanced stereo input jack, impedance value 47kΩ), a SEND output (1*1/4" unbalanced mono output jack, impedance value 510Ω), a RETURN input (1*1/4" unbalanced mono input jack, impedance value 1MΩ) and a PHONES output (1*1/8" stereo output jack, impedance value 47Ω)1.
What the FX150 does
Flamma describes the FX150 as boasting 160 types of unique effects, ranging from modulation and delay effects to tonal presets, preamps and amp simulation models1. The effects are organized into 10 effects modules, and the 5-inch color LCD touchscreen is the main editing surface: Flamma says you can easily adjust the effects chain between those modules on screen, which brings convenience on practice or performance1. For a player used to small menus and hidden button combos, a touchscreen multi-effects unit puts the whole signal chain in front of you, and it is the feature that separates the FX150 from smaller screen-less units in the same range.
Presets run to 180 preset modules, and Flamma states you can modify and overwrite presets using the FX150 editor software across 180 user slots1. On stage, three footswitches control presets and effects for complex live setups, with two different footswitch control modes to choose between1.
The FX150b variant differs in finish and power: it is the version Flamma offers in a color named Nebula Green, and it is battery equipped2. Both were announced together as 2023 new products1.
Connections and the effects loop
The FX150 has an integrated FX LOOP. Flamma explains that you can use the FX150 with an amplifier via the Four-Cable Method, and also add your own pedals into the effects loop1. In practice that means the unit can sit at the front of a traditional amp rig while its time-based effects run through the amp's loop, or it can act as the loop host for pedals you already own.
The jack field, as specified by Flamma1:
| Jack | Type | Impedance |
|---|---|---|
| INPUT | 1/4-inch unbalanced mono input | 1M ohm |
| RETURN | 1/4-inch unbalanced mono input | 1M ohm |
| SEND | 1/4-inch unbalanced mono output | 510 ohm |
| STEREO OUTPUT | 1/4-inch stereo audio output, unbalanced | not specified |
| PHONES | 1/8-inch stereo output | not specified |
| AUX IN | 1/8-inch unbalanced stereo input | 47k ohm |
| EXP 2 | 1/4-inch TRS jack, for external expression pedal | 10k ohm |
| USB | 1x USB Type-C port, USB Audio for OTG recording | not specified |
The EXP 2 port takes an external expression pedal on a 1/4-inch TRS jack1, which pairs with the unit's expression control options for live parameter sweeps. The USB Type-C port carries USB audio for OTG recording, so the FX150 can feed recordings directly to a connected device1.
Impulse responses
The FX150 loads impulse responses in WAV file format at a sample rate of 44.1 kHz and a sample accuracy of 10241. Those are the common specifications for third-party cab IRs, so IR files from most IR vendors can be loaded into the unit to shape the speaker simulation side of its amp models.
Where it sits in Flamma's range
The FX150 is the touchscreen model in Flamma's multi-effects line. Players who want a smaller or simpler unit can look at the FX50 or FX100, while the FX200 and FX200b sit above it in the same series. Flamma's smaller multi-effect pedals, such as the FS05 stereo multi-modulation and the FC05 Mod mini multi-modulation, cover single effect categories rather than full rigs. For the wider category, see Multi-effects Pedals.

Questions
Does the Flamma FX150 have an effects loop?
Yes. Flamma describes the FX150 as having an integrated FX LOOP, which lets you run the unit with an amplifier using the Four-Cable Method and place your own pedals into the effects loop. The loop is wired through a 1/4-inch unbalanced mono SEND output and a 1/4-inch unbalanced mono RETURN input, both on the rear panel alongside the main stereo output.
Can the Flamma FX150 load third-party IRs?
Yes. The FX150 loads impulse responses in WAV file format at a sample rate of 44.1 kHz and a sample accuracy of 1024. That covers the standard WAV cab IRs most IR makers publish, so you can bring your own speaker responses into the unit rather than relying only on its built-in models.
Can I connect an expression pedal to the Flamma FX150?
Yes. The FX150 has an EXP 2 port on a 1/4-inch TRS jack with an impedance value of 10k ohms, which Flamma specifies for connecting an external expression pedal. That gives you hands-free control of parameters such as delay mixes or modulation depth while playing.
Does the Flamma FX150 work as a USB audio interface?
The FX150 has a single USB Type-C port that Flamma specifies for USB Audio for OTG recording, meaning you can record the unit's output to a phone, tablet or computer over USB. For details on sample rates and driver behavior, Flamma's own product page and documentation are the reference.
What is the difference between the FX150 and FX150b?
The two were announced together as 2023 new products. The FX150b is the variant finished in a color Flamma calls Nebula Green, and it is battery equipped, while the FX150 is the standard version. Both share the same multi-effects platform, touchscreen and preset system.
How many presets does the Flamma FX150 have?
The FX150 offers 180 preset modules, and Flamma states you can modify and overwrite presets using the FX150 editor software across 180 user slots. Presets and effects are controlled from the unit's three footswitches, which offer two different footswitch control modes for live use.
