iamqman's review"Boss and Fender"

Boss FBM-1 Fender '59 Bassman
This pedal is a team-up between Fender and Boss to create a pedal that closely resembles the tone of a vintage Fender 1959 Bassman. This pedal is a cool little device for trying to recreate those vintage tone that have now become infamous in rock and roll history.

This pedal was unique in a few ways. Normally Boss would silk screen the pedal name and model on the front of the pedal. On this pedal you had a glued on sticker that said Fender Bassman Boss FBM-1. You also had a textured finish on the casing of the pedal where as all Boss pedal are painted. What is also different with this pedal unlike any Fender Bassman is the gain control. The original Fender Bassman never had a gain control. So this is a modern take in a compact Boss pedal of the original Fender Bassman in a amp simulation circuit.

This pedal uses COSM technology which is a modeling based circuitry. That is all I know about ti. The pedal does have a Fender bassman quality but to the Fender bassman get most of its charm and character from the power tube interacting with the preamp tube section. The tone of the Bassman is a clean tone that has a good punch and drive and so it is understanding that Marshall would get their first design concept from this circuitry and amp.

The pedal has some good tonal qualities and a good overall smooth distortion and drive. it cannot be capable of the real tube amp tough but it is a cool pedal nonetheless.


At new these pedals come in right around $119, which isn't bad for this pedal. It is an inexpensive way t get that famous tone as a close as you can without spending the money on a real amp. I have seen real Fender bassman's go for well under $800 so I would save up and buy one of those instead of this pedal. If you need something now then this is a good way to try it out.

Boss FBM-1 Fender '59 Bassman
BOSS supposed to emulate the sound of a Fender Bassman.
a good point, the settings are quite full.


I have a real Bassman, but too heavy to be repeated so I wanted a pedal that would allow me to get the same sound on a small tube amp.
settings are effective there is a good sound on. the pedal is very solid as always with Boss.


go to the sound, it is far from a real Bassman.
I can compare I can tell you that it's not that at all.
the sound is still good and you can can get nice things.


Pedal to try if you get the chance but do not get any illusions you will not have the sound of a Bassman.
did not have the expected result I would not recommend this pedal

iggy25's review (This content has been automatically translated from French)" Bassman canned"

Boss FBM-1 Fender '59 Bassman
Reproduces the function of the amp it simulates.
Presence, bass, tremble, medium, gain.
Two entry: normal and bright
In addition level
A good place for bosses who did not take the shortcut of a single kind of tone knob


Difficult to find the right settings to get sound from the bassman amp which is sent.
I said I tested it on a Fender Vibrolux and an orange rocker 30. In the Vibrolux is already plugged into the bright channel, the channel of the bright boss was too "bright" and therefore out of mind bassman. Against by the rocker, the bright channel then the boss got my favor. In addition, I have the impression of the presence and use tones to correct the sound and not to create it even if settings are effective.


The report from the real bassman sweated that I could try is frankly not bad at all. We recover the inflection and spirit of the amp. However, all seems a bit less bite than the amp simulation (but my memory plays me music perhaps towers?)
Beyond the copying, not the pedal reacts badly and overcharged the registry blues / rock suits him perfectly.


I share with another audiofanzien against my TS9. I would not make any comparison between her as different in their basic purpose.
Skeptical of the sound reproduction of a legendary amp, I confess to believe even if a handful of euros we do not have the same final result, we're not far.
However I'm sure the final result is closely related to the amp where it sends the boss. On my config, impeccable ... but on the neighbor???

celtwyn's review (This content has been automatically translated from French)"Superb"

Boss FBM-1 Fender '59 Bassman
This is an amp emulation Bassman'59 Fender
It has six buttons that are on the same four locations (2x2)
1 - Outside: Medium - Interior: presence
2 - Bass
3 - acute
4 - Outside: Level - Interior: gain
Two separate input Bright or Normal (one active input switches the other, you can not connect two cables together)
- Output (logic)


configuration is simple, one button "presence" may seem puzzling, it changes the sound according to its location ... to test or even because it's subtle ...
the user manual shows possible settings, but you can do what you want.

Caution for sound, it is not enough to turn the "level", we must also put the gain knob at 9 o'clock, because if you leave at least, no sound comes out, even if you turn the bottom level

a small flat on the presentation that can be misleading:
Presence button - Middle, "Presence" is written above and it is the inner knob
Level button - Gain, "level" is written above, but this is outside the button ... This inversion is disturbing at first, because it is believed to turn the "level" and you turn the gain if we do not watch out for registration reversed ...

And the thing that I drunk is having to unplug and replug the jack if I want to switch from Normal to Bright's ... there I found that Boss could have made us one entrance with a small selection button, know so well as do our enthusiast tweaking pedal as MSMworkshop ... or they could have doubled a third button with a external button selection (to avoid damaging their design Boss) ... or put out a "remote" to select the channel ... or a channel selection that changes when you press the pedal, as the Boss Dual Overdrive SD-2 ... When they want, they know very well done!
They think what these engineers?? They believe that the disconnect and reconnect their musicos pedals on stage as it quietly? ("Attention Fred I unplug ..." Plok "... Attention Fred I reconnect ..." Plok "..")

Anything! For these details I would not feeble note 10/10, because then I think they could do better!


I have a simulation on my Bassman Fender Mustang, in general (for those who know) I prefer the yellow preset, but there are basic overdrive it and I do not like. If we exclude the gain of the amplifier without affecting the other buttons, you get the same sound quaziment by plugging the pedal on the Bright channel, and by setting it in the next clear indication of the manual is to say:
- Middle and low: between 1 and 2 hours
- Presence and treble between 10 and 11
- Gain level 9 and 12

So why buy a pedal if I already have a simulation on the amp? Because I found the best on the pedal. I can already adjust the mids on the pedal, then I have no midrange knob on the amp, then I much prefer the overdrive pedal with that amp.
I play a Rickenbacker, which already has good bass and treble control side, this pedal allows me to deepen my lower back of the midrange (I like the clean sound but hot)
As I have a stereo output on my guitar, I can separate the neck pickup (bass) and connect via the pedal on a bass amp, which gives me a warm bass sound, so I can juggle a guitar sound electrical (acute) in a deep bass sound, see the two play together.
I tested on a small travel guitar Shorty and frankly there is no picture, this pedal greatly improves the sound reproduction, thanks to its settings I can lower the treble (too present on the shorty) and give it more low and medium she has not because of his mic stand. The result is magnificent compared to the basic sound of this shorty.
Bright sound is clearer (hence the name ...) there are more highs, so more clarity and brilliance ...

I love the sound of this pedal as soon as I plug I can play with for hours and dream that I have a real Bassman ... In fact it's almost better than a real, because the real button does not "gain" but a volume "Bright" and volume "Normal" .... :-P
Although the result will always depend on his guitar, pickups of the guitar and the amp used ... Me personal, I am fulfilled, I looooooves ...


I bought this pedal used in very good condition for its price argus (of time) and I am very happy.
I would not buy new because they did not find info or video convincing frankly, I wanted to test myself and see if it suited me, and be able to sell if the price of 'argus without losing too much money on it .... Well, I'm not ready to sell it, no, I jealously guard, and look more issue I find very beautiful, even in case it is very classy. :-)

I have not yet tested on a low, but I will publish my opinion when it's done.

Boss FBM-1 Fender '59 Bassman
Effect guitar or bass?


Yes very ssimple


I tested with ... Ibanez SR500 bass and a Trace Elliot amp. I hallucinated about his ...


I just buy it. She seems quite comfortable with a low ... to give roundness and ddu punch even a little distortion if you push

woodoocry's review (This content has been automatically translated from French)

Boss FBM-1 Fender '59 Bassman
See below for details, but basically it's the same settings as the real bassman!
and look, I love it!! : D


Super simple setup, edit sounds easy, manual super clear!


At his, I tested an MG100 DFX on and I was roundly disappointed, not good at all, we will say that it has added a special grain, but it's far from the type fender, a good guy who knows that I play on the MG, it will not recognize the sound marshall ... but I was not super excited!
Tested on a harley benton a 5W lamp is a little better, the amp comes out good sound for blues, it's absolutely great, that it adds momentum, and he's less matt origin.

Tested by then gained consciousness on my bass amp, Ibanez Soundwave 65W .... er by the cons on the ass!
The sound is too large, saturation I had chills it to say ?
I even asked if it was the pedal settings I shit on other amps, but it has nothing to do .... I broke out like crazy for 1 hour on a test that was supposed to last 10 minutes .... short, on my bass amp => too terrible with my Start!


So voila, two guitars amp tested, not super packed, 1 bass amp, and is the top!
weird anyway ... I am the first surprise of the blow will use it more often because I really trip over the sound it shows!
for use at home is Bonnard, why not repeat, I will have a test during ... Still I find it a bit expensive, not even provided with power supply, that's a little ashamed cons ....

That said, I have not compared with a bassman, but I think it's not even worth trying, do not abuse it, the limit on the look, yes, but all c ... by ocntre even when it brings something interresting noise, seriously tested in isolation of a sudden marketting bassman 59 'in a pedal, if it requires deception!

Boss FBM-1 Fender '59 Bassman
Bon bah, while adj t say, right?


Super simple, there's just turn the knobs all fawn.


CF gnral notice.


The canopy comes in his bote. She's cute as hell.
Jouvre the FBM-1 and I embarked on my test, sacred baptism of fire since bb is sleep, so its first test will be on a micro cube.
So I'm looking for the most neutral position of the Cube. Jaccorde the Blade (also in the neutral position).

Dabord then, let the ractions dbilitantes? Is is really like a Bassman 59? So first, jen know (I did not compare nen). And secondly, since non cest a small pedals, so no lights, not the trunk of the bassman, not legends, lodeur, just what

However, is this a good pedals? Oh YES (with an orgasm in the text)! How can we get a micro cube dun like him?
Clean, slice and for dry trs for rhythmic funk
Clean soft flexible set arpges (position Bright)
Crunch voluptuous crmeux (espresso please!)
Crunch round both wild and

In short, it sounds this little bte and after the time I dun nai maperoit I feel like testing, I put the strap back a track and I play, I am happy.

A nice lil unit. Congratulations gentlemen Boss. But is this it sounds like a Bassman I did not test pos Next question on the Classic 50.

RaphRaymond's review (This content has been automatically translated from French)

Boss FBM-1 Fender '59 Bassman
Trs boss pedals and knobs classic concentric knobs rgl the presence, the medium, bass, treble, level and gain.
There is only one channel, switching from a perfect clean a large overdrive by turning the knob for gain.
Note the two prsence between a normal and bright.


Easy as a boss, lean to turn, you turn the knobs and you play. RAS
Note that the insertion of a jack causes the power, but it is a small delay of 1 or 2 seconds before the sound ...


Trs not effective as pedals. The fender of my first course is a little warmer but it loses momentum. My marshall, he earns a chouille dynamics and a little serious and that's ...
Then I find the saturation super cold and synthetic, rather shrill, trs transistor which, as a saturation pedals a little bad. It is significantly below a TS808 for example.
The EQ is not super effective, but may be the band mdium gives a lot of warmth and brightness to the sound quite enjoyable.


It is my first, I do not envy him, I feel it's a PDAL which serves nothing. The clean sound is not transcendent and saturation is synthetic ... Ho hum just a. Certainly we gain a certain douveur and heat in the low and lower-mdium with some compression too, but it's good trslger, a good compressor / EQ could do the same.
I try in the back of the loop, it's ugly and we feel that it lacks a pramp (like when you put a direct distortion pedals into a power amp what), but in the pr amp is not great either, not much has changed much.
So I do not know APRS bassman, I never over jou ... M'enfin good, has not give the impression of dealing a legendary amplifier, far l.

Boss FBM-1 Fender '59 Bassman


As ahbitude at Boss is simle trs (turn my pots) to quickly find the sound you are looking


I could compare it with the 65 Deluxe. It took me some time to choose. Without entering it into long discussions that I diaries: Deluxe trs pramp well. The most Bassmann miscl the crunch and drive. And finally a more "original. Raliss Tests on a classic 30 and a tlcaster Baja.
Note in addition that the pedals makes sense with double single coils with this quickly become rough.


It is a good alternative for those who can not afford a home Bassman.
A try before you buy and we need to spend time changing time is not his game to get out the juice.
