Taking a 1968 classic and giving it a modern makeover, the LPB-3 Linear Power Booster from Electro-Harmonix is a versatile boost pedal that offers up to 33 dB of clean gain. Combined with an active 3-band EQ with fully parametric mid level and frequency controls, you can deftly sculpt your tones and provide the right amount of gain for any application.

Along with adjustable mid level and frequency, you can select a wide or narrow Q (Low/High switch) for the Mid frequency control, offering powerful tonal shaping to cut through any mix. You can select between a maximum of 20 dB boost for dynamics or 30 dB boost for driving preamps to saturation. Pre-Gain lets you control gain levels before the EQ circuitry. And with a high internal operating voltage of ±15V, you get increased headroom, ensuring even more detail in your tone hits your amp, DAW, or PA system with utter clarity. The LPB-3 includes a 9V power supply.

The LPB3 sports 3-band active EQ with fully parametric mids for precision tone shaping.

• Treble knob boosts or cuts frequencies above 3.2 kHz
• Bass knob accentuates or attenuates frequencies below 240 Hz
• Mids frequency knob sweeps cleanly from 240 Hz to 3.3 kHz
• 2-way Q switch sets the resonance (or bandwidth) of the Mid EQ, with Low offering a broad Q and High providing a more narrow band for a more peak-like sound

A sliding switch under the bottom cover allows you to select true bypass (left position) or buffered bypass (right position). With true bypass, your tone remains uncolored and pure as it is passed directly from the input to the output. With buffered bypass, your signal is passed through a high-quality op-amp before reaching the output, injecting a small amount of warm color but also boosting your signal integrity for long cable runs or complex pedalboard configurations.

While most guitar pedals operate internally at the same voltage as their power input (9V), the LPB-3 boosts internal rail voltage to ±15V. This higher voltage allows the peaks and valleys of the voltage range to be greater, ensuring higher headroom and detail of signal amplitude before it is approximated at the amp input. In essence, this allows more dynamics and more detail of your tone to successfully arrive at it's destination, providing a greater sense of volume with a less compressed sound when driven.

Q: 1. Does this bag come with any partitions so the light aren't resting on each other? If not, any recommendations on where to get some?

A: No, it does not come with partitions.Porta Brace recommends Porta Brace LPB-LED2A Two-Light Case B&H # POLPBLED2A MFR # LPB-LED2ABut that is for two lights and that is all that will fit in the LPB-LED3 case.There are some covers not cases that might work but it depends on the specific led light one has.

Q: 2. Why some of them are with red QR button/switch?

A: The red quick release button is specific to the Pan/TIlt head, from Syrp, in the display to indicate that the feature is in use.

Q: 3. Can this work with any slider?

A: This product is compatible with Third-Party Sliders, it should work with almost any slider.

Q: 4. Does this unit come with the capstan MFR #SY0038-0006, or does that need to be purchased separately?

A: Yes the capstan is already included with the Syrp Genie II Linear.

Q: 5. I'm assuming that a ball head quick release plate will screw onto the bottom? What are the limitations?

A: I use quick release plates on mine all the time. Balance can be a little odd but nothing unusual. The only real issue is the flexing of the the plastic portion that surrounds the side of the camera. As others have noted it has a gap. Feels funky but really is not an issue. It is a good product.

Q: 6. Does it further improve auto focus performance? or is it the same as in-camera boost mode?

A: It's slightly better autofocus. Fuji's detailed page explains the precise differences. Shooting interval goes from 0.19 sec. to 0.17 sec., shutter lag from 0.05 sec. to 0.045 sec., blackout time from 130msec. to 114msec., and finally high speed shooting goes from 8 fps to 11 fps.In practice the difference if fairly minimal.

Q: 7. How much does the grip extend movie recording for resolutions lower than 4k?

A: It's the same, 30 minutes. The limit is due to heat and preventing the camera form overheating.

Q: 8. What's the weight (either with or without batteries)?

A: The item is so new that at this time Fujifilm does not list the weight. My guess is without batteries it is about 0.5 lb.

Q: 9. Can this grip use the newer NP-W126S batteries or just the older NP-W126 batteries?

A: The grip works fine with the older battery. Fuji claims the newer battery is necessary to get top performance. I haven't had mine long enough to figure out what the real differences are.

Q: 10. What is the 2.5mm jack for?

A: The 2.5mm jack on the Syrp Genie II Linear is intended for use with shutter release cables, for time lapse photography, with compatible models. https://bhpho.to/41nTSpn
