One Control LX Tuner with BJF BufferWhat do we all need from a tuner? Something reliable that does not change the tone of your instrument, a unit with a great display that is easy to see on dark stages and in bright sunlight, and a high quality signal buffer to keep your tone pristine. Above all, you need a tuner you can trust to be ready for you in all situations. In the old days, many tuners had built in buffer circuits.

What do we all need from a tuner? Something reliable that does not change the tone of your instrument, a unit with a great display that is easy to see on dark stages and in bright sunlight, and a high-quality signal buffer to keep your tone pristine. Above all, you need a tuner you can trust to be ready for you in all situations.

In the old days, many tuners had built-in buffer circuits. Usually by incorporating the buffer circuit into the tuner pedal at the start of the pedalboard signal chain, there would be no attenuation of signal after that point in the signal path. Unfortunately, the buffer circuits usually changed the tone, which resulted in many players demanding “true bypass” effects and tuner units.

The perfect tuner should never change the original tone and sound of your instrument. However, there are many benefits to having a properly designed buffer circuit in your signal chain. With a well-designed buffer, you don’t have to have a true-bypass tuner only – you can have the best of both worlds.

In some cases, a buffer may not be needed or wanted within your chain. In the older-style circuits, the impedance changes through buffer use and effects that are used to being connected directly to the guitar (such as some old-school fuzzes) may change the sound in unwanted ways, as well as change the response and feel of these pedals. We have equipped the new LX TUNER with an ON/OFF switch to bring the BJF Buffer circuit in or out of the circuit in case you are using effects such as these. You can use the LX TUNER as both true bypass or with the BJF Buffer as needed.


THE BJF BUFFER:
This amazing circuit is installed in many switchers from One Control, and is one of the most natural-sounding buffer circuits ever created that destroys the old image people have from using old buffer circuits that changed the tone of the instrument.

Features:
Precise Unity Gain setting to 1
Input impedance will not change the tone
Will not make output signal too strong
Ultra-low noise output
If the input is overloaded, the output tone will not be degraded.

Created at the request of many of the world’s greatest guitarists by Björn Juhl, one of the greatest amp and effects designers in the world, the BJF Buffer is the answer to keeping your tone pristine in all sorts of signal chains, from the stage to the studio.

Even when the LX TUNER is in bypass mode, the natural tone is not degraded in any way, while at the same time the signal itself is made stronger and more robust to prevent any attenuation due to poor connections from cables or connectors in the signal chain. When the LX TUNER is activated, the output can easily be muted for silent tuning. Our smaller housing does not take up any extra pedalboard real estate, allowing you to make the most of your precious pedalboard layout. This is the tuner with buffer that has been demanded by guitarists and bassists- the One Control LX TUNER with BJF Buffer!

Ultra-high precision tuning circuit – the LX TUNER with BJF Buffer uses the Korg Pitchblack Custom circuit (licensed by One Control from Korg, Inc for this unit). This latest iteration of the Korg Pitchblack tech has a beautiful, three-dimensional, and stunningly visible display with new ultra-high precision tuning resolution of plus/minus 0.1 cents in strobe mode. The tuning is responsive and fast for ease of use on stage, and yet accurate enough to set intonation on your instrument, like the expensive strobe tuners from the old days. You can tune easily while changing the display mode if you want a different view.

Four Display Modes – In addition to the standard “A Mode”, the LX TUNER has “STROBE MODE” and “HALF STROBE MODE” which shows pitch changes in the direction and speed in which the meter moves, making it very easy to see even small discrepancies in pitch, from top to bottom when aiming for the reference line. There is also a “Regular B Mode” which is a unique vertical display if you would prefer a different visual orientation for tuning.

Calibration settings for a wide range of concert pitches – the LX TUNER can set the initial reference pitch of A4 between 436 to 445 Hz in 1Hz steps. Just by changing the reference pitch by 1Hz, the vibe of a track may be completely different. By being able to use all of these various concert pitches, you can tune with confidence regardless of the playing situation or other instruments you may be called to tune with.

Long Battery Life – The LX TUNER with BJF Buffer can be powered by any standard center negative 9vDC power supply, as well as standard 9v batteries. You can use the LX as an auxiliary power supply in case of trouble onstage, or you can tune off-stage and away from your power sources when needed. Or simply carry the LX TUNER with you in your gigbag for quick, convenient tuning backstage or in the studio.

Convenience – In the last few years, “clip-on” tuners have become popular with guitarists and bassists. These utilize a microphone which picks up the signal electro-acoustically – which is great if you’re in a silent room by yourself. However, once you are in the band room for rehearsal or at the live show with other loud instruments, these types of tuners will become confused by the plethora of vibrations they will pick up from the other players, the PA system, and the ambient noise. With the LX TUNER, you can be sure that only your instrument will be detected so that you can tune reliably and quickly with no interference from other sounds no matter how loud.

Super high visual resolution and visibility, quick detection of incoming signals, ultra-high resolution tuning steps, the world-class BJF Buffer for sonic purity, and the precision manufacturing and high-quality components that One Control has been known for – the LX TUNER with BJF Buffer is our answer to what guitarists and bassists have been asking for!

Decent pillow; medium-firm; heavy
Style: King - Medium
I was looking to replace my old latex pillow from BBB. I have tried several but finding just the right one has been elusive. Although expensive, I was confident this would be THE one. Sadly, it isn't. For a latex pillow, this IS really nice. It is comfortable and solid latex - hard to find. It is medium-firm and has decent spring back. But for me, it doesn't have enough sink. It is actually too firm and I felt my neck was cranked all night (I am 5'6", 135#, side sleeper, ordered the 6.5" one). I do think the cooling Purple grid works pretty well but at the same time, I could feel the grid under my pillow case. The pillow is very heavy.

It’s $30 to return and quickly STINKS from body heat
Style: Standard - Medium
Original review about $30 return below, but since it cost to return I gave it to my husband. He’s a hot sleeper so other than this pillow we’ve switched to all cotton, linen or wool bedding and it’s made a huge difference. (Polyester is plastic so it reflects your heat back to you and makes you sweat more and doesn’t breathe.) I truly would not have kept this pillow except $30 felt like a waste just to return and he got excited about it. So okay, it’s his. Well I’m the laundry queen in our household (he does all dishes) and I realized very quickly this pillow would need to be washed OFTEN. Like, once a week is NOT enough. Something about body heat and this material smells HORRIBLE. Washing it is obviously not easy, so I handwash the outer layer of the pillow with a very gentle soap (bought for silk). And then it has to hang dry. It doesn’t matter. I can clean it perfectly, no smell remaining whatsoever, but after two nights, it’s so strong I can smell it JUST STANDING NEAR THE BED. Look. I mentioned my hubs sleeps hot, sure. But he’s hygienic. This should not be such an issue. It’s never been an issue with any other pillows. The smell doesn’t even smell like him or like B.O. or anything. It’s awful and legitimately churns my stomach. But can I throw out the stupid $200 thing? Noooo. Now he’s attached. And I’m spending hours of my life each week washing it to keep from feeling sick sleeping near it at night. And to avoid having wasted $200. Hate this thing. DON’T BUY THIS STUPID PILLOW. Dropping from 2 stars to 1 Because of the smell. Original review: I thought I could buy this and see if the height would work for me. It didn’t, and pinched my neck instead. But now the *only* way to return it is to ship through UPS (not return to the UPS Store or Kohl’s or Whole Foods, which would be free). I was going to return it and try a different size, but such a high price just to *try* it is not worth it to me. I’ve returned much larger (defective) items in the past without hassle or cost (like an entire heavy duty garage shelf with broken pieces). Had I known, I would not have ordered in the first place, so I hope this saves someone else. As for the pillow itself, it was unique, but I couldn’t even really lay my head on it for more than a moment until I had let it air out for more than a week. It REEKED upon arrival. My husband said it smelled like ozone, and my brother compared it to the inside of an airplane. It burned my throat if I tried to lay on it for more than about 30 seconds at a time. Two and a half weeks later, the smell is still slightly there. So even if it was comfy for me, I would not keep this pillow.

Best pillow ever
Style: Standard – Low
I have to say, after decades of buying all sorts of pillows, trying to work for me and my short neck, this is THE one. I bought the low profile ones and OMG it is just perfect for me. I'm finally getting a good nights sleep without fighting a pillow that is too firm or doubling a pillow that is too soft and thin. It's also not as heavy as other memory foam pillows I've tried. I hate a heavy pillow. Yet, it isn't so light weight that it gets pushed off the bed easily if you change positions a lot during the night.
