SFX Sound Pedals - 3 quick reviews - ace's ten!

I just got back from a second visit to Max at SFX Sound's house and picked up some pedals that I had ordered recently and had a quick play through them and wanted to post some pics and comments.

The pedals I have from Max are:

Micro RD - (booster / overdrive)
Micro Fuzz
Ultra Tone - (tone enhancer)
Micro Thumpinator

And here's my full setup (that needs some reworking now I have these new pedals):

IMG_9313.jpg


Firstly, before I get to the pedals, I have to give huge props to Max for being one of the nicest guys I have interacted with! He is very friendly and accommodating of all my stupid questions about tone shaping and effects. He also helped my by modding my WMD Geiger Counter (Civilian Issue) to make it more bass friendly. He let me borrow a couple of pedals to test out as well. Basically a top bloke who I would encourage everyone to support. He really knows his stuff when it comes to electronics and effects and would have no hesitation in ordering more pedals from him.

Now the pedals:

Micro RD - this was my first SFX pedal and I use it as a low gain overdrive to give me that little bit of breakup and warmth. It does the job perfectly. I generally set the volume at unity and then have the gain at about 2 o'clock and get a great warm breakup. There is almost no low end loss with the pedal (in fact, with any of Max's pedals that I have tried). I was looking at pedals like the SFT, Blueberry etc to get that low gain overdrive sound, but this pedal fits the bill perfectly, is much less expensive and is tiny. This is another plus of Max's pedals, they really are put into the smallest cases he can possibly get them in and they do maximise space on the board.

Ultra Tone - Max lent me this to try out for a couple of days and it has won a place in the "always on" spot on my board. It is hard to describe what it does, but I think its related to the Aphex Exciter / Submarine / BBE type of active tone enhancement pedal. Max might be able to add more detail about what it does, but basically it provides a great afttening of the tone and low end. It particuarly tightens up the low end when set to about 11'O'clock which is where I set it to. The range of tones is great, but it works so well with my FEA Growler that the two of the stay permanently on on the board. Highly recommended. Do not be fooled into thinking this is just a passive tone control, it is far from it!

Micro Fuzz - I really like this fuzz because there is no bottom end loss at all. I have the tone set about 11 O'clock on it and the gain at unity and the range of fuzz tones is amazing for such a small pedal. It doesn't matter how aggressive you set the fuzz, it still retains the low end so well. In fact, the only way to lose it is to wind the tone all the way up. Max based this on a Coloursound Bass Fuzz I believe. At the highest fuzz settings its quite aynthy, but I prefer it about 2 o'clock where its a but less synthy. Again, a great pedal in any sized enclosure, but given the tiny size it really does allow a huge variety of tones on a very compact pedal board. Two thumbs up.

I haven't integrated the Micro Thumpinator into the set up yet, but will try and do that on the weekend when I have a reshuffle.

I will jsut finish by saying that I can't recommend Max and the SFX pedals highly enough. He really does understand what makes a great bass pedal (ie no low end loss) and tailors his pedals to fit the bill. He doesn't compromise on quality and is very receptive to feedback. I am lucky that we live quite close so I can pop down to his "laboratory" and see what new stuff is on the horizon, but even without doing that, I would encourage you to give his pedals a try.

Just by way of disclosure, I paid full retail price for all the pedals so I am not an endorsee or anything, I just found his pedals to be worth the plug!
 
As had been said before by me many times - I really rate SFX stuff - took my X&M (crossover/mixer) pedal out for its first gig last night with my Musket in the 'high' loop - My thoughts?

"holy sh*t, it slays F*cking dragons"

Sorry for the thread derail, but I've been on the fence regarding the X&M...even to the point of emailing Max about it a hundred times or so! Could you describe how it works for your rig, or your experiences so far? I'm trying to determine if it would get me the sound I'm looking for. I'm looking to do a biamp rig similar in sound to Entwistle, or dUG Pinnick's distortion sound.

Like Spanky said, the price has kinda turned me off so far...so I'm a little hesitant to drop the money in case it doesn't work for me.
 
The Thumpinator sounds like a fixed high pass filter, but looking at the SPL chart (with no indication of db's on the Y-axis of his chart :rollno: ) it also looks like it's boosting frequencies from roughly 30-100hz. I like the idea of an HPF in such a small package, and would pick one up tomorrow if it didn't have that additional boost in the 30-100hz range.
 
Eh, it seems like some of these pedals might be a good idea, but they seem pretty overpriced to me. Enough so that it turns me off even to try them out.
Compared to what? They are very competitively priced in the UK when you look at direct competitor pedals. It may be the currency exchnage that makes it more expensive in the US but, for example the Micro RD is about 30% less than an SFT here.

Seriously? Folks, here's the chart he's talking about:

[Invalid or Expired Link Removed]

Granted there should be scale markings on the Y axis, but the two paths are so very close that the "boost" you're talking about is marginal at best, not an effect any human could ever hear.

Typically, filters are designed to have a -3dB or more at their cut-off frequency. If you look at the graph in Bongo’s post the 30Hz cut-off frequency is at 0dB with respect to the original signal, followed by a very steep slope to remove the signals below it. IME, to bring the cut-off frequency back to the 0dB point you have to tweak the filter parameters a bit, which result in a slight bump to the frequencies just after the cut-off frequency. Even if this little bump is at all that audible, a tiny adjustment to the bass tone control on your amp or guitar will quickly remedy the level.

I for one really do not see the need for having dB levels on this comparison graph, because the level of “boost” is insignificant to the entire signal energy displayed on the graph. (Signal energy is the entire shaded area of the graph.) Indicating dB levels on the graph would show the level of the signal used for the measurement, but these dB levels will be different for every instrument and player… but the signal comparison would remain a constant. Yes, I know that you can say “well how much more is that little boost”… while looking at the entirety of signal energy in the shaded area of the graph; the boosted amount is minimal at best.

A filter designed for this purpose has to have an extremely steep slope and it is a delicate balancing act to garner the response that SFX has with this design. I am not at all speaking for SFX, but as a fellow designer I applaud this design. Well done, sir!

Yes, he designed it to my specs, and I think he did an amazingly good job.

Something else to factor into the price: the internal build quality of these is first-rate, far better than the typical DIY stompbox. That may not matter to some people, but for those of us that geek out on quality, it's worth it. :)

Seriously? Folks, here's the chart he's talking about: ...

I don't doubt that the bump is marginal and possibly inaudible, but with no numbers to represent the db's in question, there's no way for me to tell. I've seen plenty of graphs (suspect though they may be) that have an exponential y-axis. If that were the case with this chart, the bump at 30-100hz could be significant. I always assume that no information means they're covering something up. This may or may not be the case with this pedal. I've not tried it, and only have an incomplete chart to gauge the pedal's performance.

Now, with that out of the way: I still really like the idea of an HPF in such a small package. If the boost is as insignificant as you guys are suggesting than this could be a real winner for me, especially given the limited real estate left on my board.
 
does any1 know of clips of the micro rd? the clips of the micro fuzz on the sfx site are done very well.

@mark latimour....this micro rd sounds very interesting to me, especially given its form factor. it also sounds a bit like a fulltone fat-boost. do you have any experience with the FB to make a comparison?

I haven't used the FB. I was speaking to Max about modding a fulltone bass drive into a smaller package as it takes up too much space. When we spoke about what I used it for (low gain grit) he sugested rather than the custom route to try out the Micro RD and it was perfect. It isn't a TS close, but the way I set the Bassdrive was not the typical TS sound, I tried to get it very lone gain with just a little break up.

Sorry I can't be more help. If you PM Max (he is on TB - can't remember his TB username though) he could defintely give you a comparison from a tech point of view.
 
I will try to address all the questions/issues that have been mentioned.

/// price
Eh, it seems like some of these pedals might be a good idea, but they seem pretty overpriced to me. Enough so that it turns me off even to try them out.

(…) Like Spanky said, the price has kinda turned me off so far...so I'm a little hesitant to drop the money in case it doesn't work for me.

As it has been said, I think the exchange rate plays a part in this. As I am sure everybody appreciates, it is something I can’t control.

I always try to avoid comments about other companies’ value/money or quality/price. If it is ok I would like to apply the same rule to [sfx] – I hope you don’t mind.

More in general terms, what SpankyPants and karter2000 say makes a lot of sense. I believe in the free market and if they feel that some other company can produce comparatively better pedals (sound, functionalities, quality, customer service) at lower prices they are absolutely right in buying them instead of buying [sfx] pedals.


/// frequency response, graph, bass boost...
[Invalid or Expired Link Removed]
I put the graph in the web page of the micro-thumpinator to offer a general idea about how the unit works. It didn’t intend to give a quantitative assessment of the frequency response.

Regarding the boost in the region of 30-100Hz, in practical terms it is just a fraction of dB – less than a human hear can detect and definitely less than it is audible in band mix. The cause is probably a combination of components tolerances, differences between theoretical values of resistor/capacitors and commercial values and last but not least environmental factors (cables, audio card...).

Thanks to Mark for writing the review, for his support and for popping in at [sfx] for a great chat about effects and signal processing.

Thanks to Bongomania for his comments and the spot on clarifications.

Thanks to boomertech – FEA Labs units are really impressive :eek:. Your encouraging words are really appreciated. Thanks.

I hope I didn’t forget anything. I you have more questions, please feel free to ask. :bassist:

Personally I find Max's [sfx] prices to be very reasonable. Especially when you factor in the quality of design and parts he uses. This is when the saying 'you get what you pay for' is true. You're basically getting hand built, one-off pedals from someone that will work personally with you to get your own sound.

Ah, but hey, that ^%$& brand name pedal that everyone and their dog has that is noisy and packs it in within a year is cheaper. I don't get it obviously. If you're not in the market for a Fodera, don't look at a Fodera and then criticize the price...
:confused:
