About this deal

It could be a myth originating from the assumption that because MOSFETs are used then they are "soft clipping", which means gate-drain. Although, having said that, the single MOSFET Q2 would be drawing very small current at a Vgs of 1.2V. This would be imperceptible.

BTW, I've seen a lot of schematics and layouts of the OCD with the MOSFET gates connected to the drains.Hope you enjoyed our Joyo JF-02 review. For more, be sure to follow Performer Magazine on Facebook. FEATURES However, the JF-2 is special because it brings two of these pedal effects in one – specifically overdrive and distortion. After testing it out in our lab, we found it to be a nice overall pedal. While it is not perfectly overdrive or distortion, it is a pretty good general gain pedal for those who need “one that does it all.” The JF-02 Ultimate Drive is actually JOYO’s best-selling pedal as far as we know.

For a more interesting function of the switch, I soldered a 4.7nF// R13 = 33k capacitor that affects the switch in the "LOW" position. Significantly boosts the frequency band from 1 kHz up (completely adds more of all mids).Many really love its rich and complex distortion character - including myself, while others prefer a slightly smoother type of distortion - which is why it's handy that there are so many clones and mods around - you can find your preferred derivation of the core flavour that best suits your preferences. In the Low Mode, the original tone isn’t messed with, and when in the Hi Mode, there’s a bit more low-mids and bass; it might be considered a “more tone” switch, in practicality. Users include: Thom Yorke (Radiohead), Ed O'Brien (Radiohead), Nels Cline (Wilco) Paul Cochrane Timmy

Ever wonder what your favorite artists have on their pedalboards? Well, we crunched the numbers on Equipboard to reveal some fun facts about the most used overdrive pedals. 1. Ibanez TS9 Tube Screamer We run them through different combinations of guitars and amplifiers, since changing the signal chain can greatly affect the sound of an overdrive pedal.Stevie Ray Vaughan was a Tube Screamer user, as can be seen in this photo of his spartan pedalboard.

This is what I was told on another forum that I asked, but wanted to make sure I knew exactly what I was doing before I went futzing around with this thing. The pure way to achieve an overdriven tone would be to push a tube amp to the point of saturation where it starts "clipping." However, doing that is not the most practical, as we don't all have tube amps that we can crank to unholy volume levels. Enter the overdrive pedal. The changes on the versions between 1.1 and 1.7 are relatively subtle, and are mainly component value tweaks to slightly alter the EQ response. The most interesting change is on version 1.3 - increasing the drive pot to 1M for more sustain, and the addition around 1.4 of a germanium clipping diode. The leap that was made with version 2 brought even more dramatic change. The three key differences are a new output buffer, a discrete 2N5457 JFET transistor input stage, which raises the input impedance significantly - as you’d find on an Echoplex or Space Echo preamp - and the option to use a new type of switching, called enhanced bypass, instead of true bypass. DriveMy educated guess is that this redesign was mainly intend to avoid possible issues on the intellectual property of the circuit design, by adding a buffer, rearranging the clipper, and changing one (insignificant) resistor value. The 9V battery compartment might be considered a bit cheap and the “Darth Maul/demon skull” graphics are admittedly kind of cheezy. Considering the price and the tone, though, it’s a minor detail and easy to overlook.
