Useful Arts took the audio circuitry of the BF-1 and coupled it with the linear power supply from the SFP-60. The result? Astounding clarity, headroom and noise specs that only come with the nearly-noiseless high voltage that a linear power supply can deliver.\u003c\/p\u003e\r\n\r\n\u003cp\u003eWhich one is right for you? Both have identical feature sets and audio circuitry, except the BF-S adds a ground lift for its XLR output. The BF-1 features a switching power supply, which is light, compact and convenient (no changes needed to adapt to any line voltage in any country). It's also convenient for live use and will fit in most guitar cases. With its compact size, the BF-1 has a noise floor of about 60 dB. ​ With its heavy-duty linear power supply, the BF-S has a noise floor of better than 70 dB - almost unheard of for tube gear. With this power supply, the BF-S is flat from 15 Hz to 80 kHz (-2 dB)!\u003c\/p\u003e\r\n\r\n\u003cp\u003eThe BF-S weighs a good bit more than the BF-1, and is encased in a powder coated steel enclosure to withstand the rigors of daily use on a tracking room floor. ​ Most tube DIs start with the design philosophy of a guitar amp.

And to most ears, the bare sound of a signal from an average microphone through an average preamp, standing by itself, is pretty good. Yet dropped into a mix, that perfectly \"fine\" sound is dead, lifeless and lost. So begins the cycle of processing, the quest for the one magic box or plugin (or series of them) that will make things sound like they're supposed to. The result is usually a louder, heavily effected but even more lifeless signal that can't quite find its place in a mix. ​\u003c\/p\u003e\r\n\r\n\u003cp\u003eIt turns out that fewer, not more, knobs and buttons are the key to incredible sound. In the early days of recording, the overprocessing phenomenon didn't exist. Records were recorded to one or two tracks, and whatever was heard in the room during the performance was heard by the public - simple as that. And it sounded great -- with no post processing at all. The key was that the sound was preserved in all its natural glory before recording. It's a lot like the difference between fresh food and microwaved food.\u003c\/p\u003e\r\n\r\n\u003cp\u003eIn a preamp, you need a creative tool that complements the other main tools available: EQ, compression and time-based effects. None of those tools can make one preamp sound like another. So let’s get to what’s going on under the hood.\u003c\/p\u003e\r\n\r\n\u003cp\u003eThe sound of the SFP-60 is more clear, present and edgy than dark and creamy, and is specifically designed to make vocals sound forward and intimate. Useful Arts have accomplished this by using tubes for what they are best at – accentuating harmonics that make sound more clear and pleasing to the ear and brain in the real world. Different tubes have different properties. Properly used, pentodes add third-order harmonic content that contributes the the “clarity” and “bite” associated with the sounds of the great early radio recordings. Triodes contribute more second-order harmonic components, which add a richness, or “thickness” to the sound without sounding dark. (Note: These are subjective impressions. People can and do debate these adjectives for a lifetime). The SFP-60 input tube is an EF-806 pentode, and the final 2 gain stages are high-current ECC82 triodes. 12AX7s, which are wonderful in guitar amps and form the basis of many mass-marketed tube mic preamp circuits, are nowhere to be found in the SFP-60.\u003c\/p\u003e\r\n\r\n\u003cp\u003eThe character of the harmonic distortion in a preamp has a spectral effect that we intuitively think of as EQ-related, but in reality is completely different from EQ. EQ filters give you more or less of what you put in (and normally introduce undesirable phase shifts too), while the preamp is actually adding signal that isn’t present in the original signal. Because this addition is not a perfectly faithful reproduction of the input signal, it’s called distortion (even though it sounds nothing like the clipping distortion generated by a guitar amplifier). Every audio device that has ever been made introduces distortion, so we might as well make it a good thing.\u003c\/p\u003e\r\n\r\n\u003cp\u003eIt turns out that distortion can be quite useful. Every sound we record will have to be reproduced by a mechanical speaker of some sort, and the right kind and amount of distortion can actually help the speaker do its job by compensating for the inadequacy of the reproducing device. In this way, distortion can actually help make a recorded sound seem more real at playback.\u003c\/p\u003e\r\n\r\n\u003cp\u003eEnter the color knob on the SFP-60. Unlike most preamps, which are designed to maintain a predetermined ratio of distortion to gain, the SFP-60 puts the artistic choice of distortion in your hands. At a setting of 0, the preamp is very, very clean – it sounds “polite.” A setting of 10 will add about 10db of gain and increase the distortion artifacts by nearly ten times. The result is an aggressive, full sound that stands out in a mix and grabs the listener's attention. That’s an incredible creative range, and it gives the SFP-60 the ability to offer very different sounds for different tracks and different sources.\u003c\/p\u003e","brand":"Useful Arts","offers":[{"title":"Default Title","offer_id":44450520367207,"sku":"131371","price":2999.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8848\/5479\/files\/useful-arts-sfp-60_131371_1_3cbdb85b-2c77-4127-9ac3-3e819372906d.jpg?v=1787093396"},{"product_id":"useful-arts-bf-1-tube-instrument-preamp-di","title":"Useful Arts BF-1 Tube Instrument Preamp\/DI","description":"\u003cp\u003eThe \u003cstrong\u003eUseful Arts BF-1 Tube Instrument Preamp\/DI\u003c\/strong\u003e is an all-purpose interface for any instrument with a pickup that enhances clarity, detail, audibility and dynamics whether used between the instrument and amp, the instrument and a PA or recording device or all of these at the same time.

All amplifiers make the signal do actual work to drive the input stage.  The problem is that the most delicate parts of the signal aren't capable of doing that work, and are forever lost.\u003c\/p\u003e\r\n\r\n\u003cp\u003eIt boils down to input impedance.  The higher the input impedance, the less work the signal has to do before it is safely amplified.  Consoles and recording devices usually have an input impedance of around 10,000 ohms - way too low for a pickup.  Plug a guitar or bass directly in and it sounds lifeless, small and completely lacking in detail and low end.  With a piezo pickup, it sounds thin, buzzy and grating. Guitar and bass amps have an input impedance of several hundred thousand ohms - a big improvement.  Instruments sound bigger, fuller and more detailed.  This is why the traditional approach for recording or live gigs has been to run the instrument into a DI for the console and back out to the amp.   The normal DI replicates the input impedance of the amp, converts it into a signal the console can use, and all is well.\u003c\/p\u003e\r\n\r\n\u003cp\u003eWhat if instead of a few hundred thousand ohms there was an interface with 20 million ohms input impedance?  Well, this is what Useful Arts has created.  And the results are astounding.  Now you can observe even the tiniest details in the signal without ruining it, and pump the results out to an amp or console with the full detail in useable form.

Everything sounds better.\u003c\/p\u003e\r\n\r\n\u003cp\u003eIt turns out that tubes are uniquely well-suited for this task, because they are inherently capable of creating ridiculously high input impedances.  Passive DIs use transformers, which can't effectively create such high impedances.  Active Dis use low-voltage FETs, which sound like .... transistors.  And they usually offer input impedances far lower than a good tube stage anyway.  But wait!  You already have a tube amp - won't that do the trick?  Nope.  Amps use tubes as high gain stages, and that drastically lowers their input impedance.  They benefit hugely from the BF-1.  The BF-1 uses the input tube the same way as a tube microphone - to convert impedances without the high gain.\u003c\/p\u003e\r\n\r\n\u003cp\u003eThere are other tube DIs out there, sure.
