FLAMMAFX20 Guitar Headphone Amp with APP 40 Drum Grooves 52 Amp Modes 5 Delay 5 Reverb Effects 14 Modulations for Practice Recording and Creativity

With decades as a guitarist, I've had any number gadgets over the years. I have used the Vox headphone amp for quite a few years, but with the purchase of another new axe, I decided to see if there was something "new". Thus, I came across the Flamma FX20. What appealed to me was: 1) more amp and effects models, 2) an iOS app for max control, 3) Bluetooth input of music tracks for accompaniment, and 4) the addition of drum tracks. I also wanted something that was rechargeable instead of having to always worry about batteries depleting.Overall, I’m pleased with the unit, but do have a couple issues. So far I’m fairly impressed with the amp and effects modeling. My practice amp is a Vox Valvetronix with absolutely exceptional models of various vintage amps and effects. While the Flamma is perhaps not quite as good, for its size and price I can’t really complain. It’s also nice to be able add a drum track for jamming. I can also say that the iOS app is fairly good and connects to the dongle via Bluetooth instead of requiring a hardwire connection like the Vox app for the Valvetronix. I also like that I can play along to music from my iOS device via Bluetooth, thus making all connections to the app and music track wireless. (And, no, the unit does not have support for Bluetooth wireless headsets.)Probably my biggest “complaint” is the setting of the 4 presets for amp/effects available on the dongle when not connected to the app. Listening to a YT video demo of this unit and following the very limited instruction manual (there are none for the app, sadly), it appears that in the app there are 10 overall sets with 4 presets available in each set (40 total presets). Only one of the 10 sets of 4 is available on the dongle if not connected to the app. It appears that whatever set you quit the app in, that set of 4 presets are then available to switch between on the dongle (when not connected to the app).Each of the 4x10 (40) presets in the app can be modified to an extreme with any combination of 52 amps, 14 modulator pedals, 5 delay pedals and 5 reverb pedals. Yes, you can come up with almost any imaginable “sound” — with the odd exception of an overdrive pedal. Of course, you can adjust the various amp settings for overdrive, so not impossible to get the effect/sound, but it would have been nice to have an overdrive effect/pedal.My biggest disappointment is that there is no “spare” bank or banks to store your own custom presets. Thus, while you can go in and set up or modify any of the 40 presets, once they are modified and you want to save the new one, apparently you are required to overwrite an existing preset. Thus a HUGE caution!!!!! If you save a new one, you might want to write down the exact settings from the stock preset before doing the save!!!It also appears that if you want to have 4 custom presets available of the unit when not connected to the app, you need to overwrite all 4 within the same set (sets are identified as 0A, 0B, 0C, 0D, 1A, 1B…etc. up to 9A, 9B, etc.). Thus, you will have to overwrite 4 of the stock presets in order to get your own 4 special presets. Then before quitting the app, be sure you are in that custom set before quitting the app. The dongle will then rotate between that custom set of 4 modified presets when pushing the dongle's Preset Selection button.It is also nice that you can connect the dongle via USB cable to a computer or iOS device to input the sound (including drum track) to that device and into something like GarageBand/Logic, etc. for recording.Pros:• Works with iOS and iPadOS• Modeling of amps and effects is quite good• Compact• Rechargeable (USB)• Bluetooth for app connection• Bluetooth for music input to headphones from iOS• Decent selection of drum tracks• USB output to a device for recording• Posted a question and within 24hrs had a response from FlammaCons:• Cannot save modified presets without overwriting existing presets.• Cannot switch between sets of 4 presets (there are 10 sets) unless connected to app• Instruction manual is very, very limited and somewhat inadequate• There is no instruction manual for the app leaving a person reliant on YT videos and guessing

I have issues with getting headphone amps to work with this ukulele. The Fender Mustang doesn't work and requires a pre-amp (rare and found one from China that uses CR2032's), but then you have a daisy chain of micro amps. It may be that I needed headphone amps that were specifically for acoustic guitars, as the VOX AC30 works with the ukulele, but then I have to carry around AAA's.This took a bit to charge to green, and I originally thought it was broke, but let it charge for longer than it's 2.5 hrs, and it finally hit green. I'm old now, so it's possible I hooked it up to the USB C and never plugged in the USB. I used a different cord, and it finally charged up. I like the drum sounds, and am only using one of the presets - my style is fingerpicking in the classical music manner, so one of the hall echo effects is what I use.It dropped my carry load from 2 amps, batteries, a cable, headphone and wire, to just the 1 amp and headphone wire. Hopefully I'm not mistaken about the charging and it does still work, but for now will play with it, travel with it, and see how it goes.

I have the FX10 and love it. When I heard the FX20 was out, I watched several videos on it and decided to pull the trigger. The FX20 is more of a down-grade and I was sorely disappointed. First of all, the swivel arm on the unit was loose causing a bad connection with the guitar which resulted in audio cutting in and out. The FX20 only has 4 savable preset slots whereas the FX10 has 14. The FX20 is mostly reliant on the App for Amp simulations and tone adjusting, which isn't awful, but it defeats the purpose if you can only store 4 presets. I reached out to Flamma Customer Service twice to address the loose swivel arm issue and they never responded, indicating they really don't care about faulty or defective equipment. If you have the FX10: keep it and avoid this version. Sometimes, newer is not better.

All sounds are really accurate and nice. I do wish it had a little more battery life though.

I previously purchased the FX10 and loved it! But programming on the device itself wasn’t easy.The second I saw that the new FX20 had an app for it, I immediately knew I had to purchase the FX20 version! Programming was a breeze and I connected to Bluetooth with no problems. It was easy to upgrade the new firmware as well. Moving to the FX20 also gave me more effects and more cabinet/amp sounds.But the main attraction is the sound … It sounds fantastic!!To hear a demo, go to YouTube and search for the “FLAMMA FX20 Review & Tutorial” from the “intheblues” channel.I own both an iPad (iOS device) and an Android phone. Flamma has an editor app for each platform. When I’m home, I use my iPad and when I’m traveling, I have my phone with that app installed. Works fine on both platforms.

It's awesome, I was skeptical at first but now it's my favorite gadget.

I bought this a while ago. I really loved this product. However, I have to honestly say. This product is not built to last.Sadly to say, the battery is defective after less than 1 year of use. The software to manage the product is outdated and will never be updated again. It no longer holds a charge and requires to be plugged in always making it difficult to use as intended.Also, the Bluetooth features are great, when paired with a phone. You can plug your headphones in it, and play music from any app on your phone to jam along with. This also integrates nicely with any standard DAW when using the USB mode while plugged into the computer.In any case. Great features, just not built to last.
