2N5457 Transistor Explained / Description:
2N5457 is a famous TO-92 packaged JFET transistor that is designed for general purpose switching and amplification purposes. It is also available in SOT-23 package by some manufacturers. Having features like high gain, low noise, low power operation due to which it can be used in battery operated devices. The transistor is designed for low gain signal amplification with good noise filtration due to which it can be used in variety of small signal amplification purposes.
Where We Can Use it & How to Use:
As mentioned above 2N5457 is designed for amplification purposes therefore it can be used in amplification of different type of low level signals whether it will be an audio signal or other type of signals in electronics. Other than that it can also be used as a switch and it can handle max load of 10mA.
Applications:
Audio Preamp circuits
Any Low Level Signal Amplification
2n5457 Substitute
Sensor Circuits
Audio Amplifier Stages
Infrared Detection
How to Safely Long Run in a Circuit:
To get good performance with 2N5457 it is recommended to always stay below the maximum ratings. Do not drive load of more than 10mA, do not operate the load of more than 25V through this transistor, do not increase drain to gate voltage from 25V reverse gate to source voltage should not be increased from -25V, and always operate and store the transistor above -55 centigrade and below +150 centigrade.

Fulltone OCD v2
One of the best just got even better.
What's New:
NEW output buffer (when pedal is turned on) which eliminates it from being influenced be effects that came after it. Translation, your sound remains consistent regardless of placement in today’s more complex signal-chains, loopers, and pedalboards. This buffer also had a positive effect on the sound, it reduced loading on the pedal’s hard-clipping stage, allowing more sustain of both the sound and the overtones.
NEW Class A configured discrete 2N5457 JFET input section, raising the input impedance from the previous 330K to 1 mega ohms and increasing the dynamics…resulting in significantly better interaction with both single coil and humbuckers.
NEW Internal switch to choose between”Enhanced Bypass TM” & True-Bypass,and with no popping sound in either mode. No other company offers EB because I invented it.
If you've ever owned a GREAT amp, like a Marshall 18 watt, a VOX AC15, a Marshall JTM45 and if you have a place where you can crank them up loud, then you know what I'm talking about...
Smack a power chord and you (not only) hear the fundamental notes...but you get (count 'em) 4, 5, even 6 additional overtones ringing into a feedback... notes that you can whistle if your ear is good enough! Think; Zep's 'Ocean,' 'Custard Pie,' Classic tones including James Gang, the Beatles, AC/DC, FREE., etc.
Back off the guitar's volume and there are a dozen great other sounds at your fingertips... Clean, spanky sounds, with all the highs and lows still intact. And a Tele still sounds like a Tele, a Les Paul like a Les Paul.
PEDALS (until now) just can't hold a candle to what a good amp can do if you are really picky. You not only lose all the touch sensitivity, but forget about those complex Harmonics. (For me) It's always been somewhat of a compromise using Overdrive pedals... until now. Ladies and Gentleman, I am proud to introduce the Fulltone OCD. I made this pedal for me, but I think you might like it too.
The Fulltone OCD (Obsessive Compulsive Drive) overdrive pedal is the perfect mate for a great tube amp. If you're lucky enough to own a Vox AC15 or a Marshall JTM45 and have a place where you can turn it up all the way, then you have an idea of what the Fulltone OCD is capable of.
Plug in the OCD pedal, lay into a bar chord, and you will hear multiple layers of rich harmonic overtones in addition to the fundamental tone. This is not a subtle effect, these are beautiful ringing feedback tones that can be easily discerned and even sung if you have good ears! The Full Tone OCD produces classic tones you've heard on records by Led Zeppelin, The Beatles, Hendrix, AC/DC and others.

Roll back your guitar's volume knob and you'll have access to a whole myriad of gorgeous tones, including shimmering, spanking, full range clean sounds. The OCD pedal allows your guitar's natural tones to bloom, so your Strat will still sound like a Strat, and your vintage Les Paul will still sound like a vintage Les Paul.

Overdrive and distortion pedals have always been something of a compromise in comparison to a great guitar amp cranked to the 'sweet spot'. Feel, tone, and harmonics often fall by the wayside when an overdrive pedal is plugged into the front end of a great amp, until now. Check out a Fulltone OCD and see what a great overdrive pedal can be!
