$269 is your absolute final/total here, for the 29 Pedals JFET pedal, from Believable Audio. Handmade in Cali!

29 Pedals JFET is a boost pedal rooted in 29 Pedals' love of the JFET transistor, long-loved in the world of audio, for its similarities to vacuum tubes. As always for 29 Pedals, the JFET pedal is a ground-up design, from a blank sheet of paper, an effort to elevate the humble boost circuit to something refined and tonally enhanced.



The JFET boost pedal has 3 modes, via the top switch... 

  • N for normal mode, where a typical boost might sit in terms of frequency response. Almost a treble boost, but not quite.
  • F mode adds a little more weight.
  • X mode flattens the circuit all the way down to below 10Hz, giving you an incredible feeling of weight, without sounding like additive EQ. The extension in the frequency response also tightens the phase, and gives you an incredible, solid feel.




The L control knob sets the level. It’s a fader after the boost circuit, and before the output driver. This means that the gain of the first stage is set, and you can use the fader to set the level into the output stage, so THD, hair, and tone remain the same throughout the travel. The output driver after the fader ensures that the output impedance remains consistent. JFET makes about 19dB of gain.



JFET can be used after a buffer or input driver (like 29 Pedals EUNA pedal), and can also function as an always-on input driver at the beginning of the board. JFET sounds great following EUNA, and also stacked with 29 Pedals FLWR and OAMP. It will drive heavy loads, and has high headroom, making it equally happy at the end of your board. JFET has the same relay based switching as 29 Pedals other pedals, plus instant-bypass whenever power is removed.

    Impressive Sound Deadening Solution with Enhanced Audio Quality
    Model: NewSLS50_52
    I recently purchased the Siless 50 mil (1.3mm) 52 sqft Car Sound Deadening mat, and I am delighted with the results it has delivered. Right from the start, I was impressed with the packaging, which ensured the product arrived in perfect condition. One of the standout features of this sound deadening mat is its ease of use. It was a breeze to cut and modify according to my specific needs. Whether I needed to cover specific areas or customize the size, the mat accommodated my requirements effortlessly. This flexibility made the installation process a breeze. The Siless Sound Deadening mat has proven to be highly effective in reducing outside noise within my vehicle. With just a half cabin install, I noticed a significant reduction of approximately 10 decibels, making my driving experience much quieter and more comfortable. The mat acted as a reliable barrier against external noise, allowing me to enjoy a more peaceful ride. Furthermore, the sound quality from my vehicle's audio system experienced a noticeable improvement. The Siless mat effectively dampened vibrations and minimized resonance, resulting in cleaner and more refined audio output. The mat's thickness of 50 mil (1.3mm) ensures optimal sound absorption, contributing to its effectiveness in creating a quieter and more enjoyable driving environment. I can now appreciate the full range of tones and enjoy a more immersive music experience during my drives. Overall, I highly recommend the Siless 50 mil Car Sound Deadening mat for anyone seeking a reliable and effective solution to reduce noise and enhance audio quality in their vehicle. The easy cutting and modifying process, along with the excellent packaging, contribute to a seamless installation experience. With a significant reduction in outside noise and an improvement in sound system performance, this sound deadening mat has exceeded my expectations.

    Good quality sound deadener at a good price.
    Model: NewSLS50_52
    Quality sound deadening that adheres to body panels well. You can easily hear the vibration reduction after just the first piece by tapping on the body panel before and after.

    Good stuff at a good price
    Model: NewSLS50_52
    Works well and sticks well. I used a roller and it has been over a year and everything still sticking as good as day i put it everywhere. I didnt use any adhesive but I did wipe everything down with acetone before I applied. Good stuff at a good price

    BUY THIS ONE!
    Model: NewSLS50_52
    This is one of the good ones. There are other brands just as good, and manny brands are worse, but this handles well, rolls down easily, doesn't come off at all easily, and adapts to dips and curves like a champ. Appropriately heavy and dead, I'm happy with the way it smothers panel resonances and even at muffling direct sound, like a big hand over my Uncle Harry's eternally noisy mouth. You can rip the foil but you have to work hard at doing that. Remember to buy a brayer; you can roll overlaps nice and thin. Also remember to pre-wipe the sheet metal with a decent solvent like acetone or Stoddard/Varsol. It should last forever.
