Hello. This is sukuta takafumi (@sukutakafumi).

Today, I would like to introduce the JIM DUNLOP / EJ-F1 Eric Johnson Signature Fuzz Face.

First of all, I made a video, so please take a look if you’re interested.
This Fuzz Face was jointly developed by Eric Johnson and George Trips, who is currently responsible for product development at Jim Dunlop.
It seems that it was created based on Eric Johnson's Fuzz Face, but it seems that it took a long time to get Eric to OK the final product.
This Fuzz Face is equipped with the BC183 silicon transistor, and has been selected so that it can produce a high-gain sound. In fact, Eric used to prefer germanium in the past, but it seems that silicon transistors were chosen in consideration of stability.
This is because germanium is more sensitive to temperature and highly unstable.
By the way, it appears Mike Fuller currently owns the Fulltone 70’ Fuzz Face pedal that Eric originally owned, and used this in the reproduction of the new one. Fulltone also has a silicon transistor and has a high gain sound. Since there is a Tone knob, it is easy to use and has a wide variety of sounds.
However, those who want to reproduce Eric's sound and those who yearn to be like Eric should definitely get this signature Fuzz Face.
If you set your Marshall to a slightly sweeter tone and connect this Fuzz Face, Eric's sound will jump out at you.
▼ By the way, the following equipment is used in the review video.
Guitar:
Kanji Guitar Telecaster (https://twitter.com/KanjiKawabata)
Effector:
JIM DUNLOP / EJ-F1 Eric Johnson Signature Fuzz Face Line6 Helixlt
The Helix is also set to a Marshall-type amp, and echo is set to a tape echo. The settings are posted in the latter half of the video, so please refer to them.
The trick to setting it up is to distort the Marshall a lightly and make sure it’s not a trebly sound using the EQ. Also, the echo should be a little stronger and not cluttered. If it doesn't work on the Helix, you can apply another clear delay or just a plain delay on your DAW.
I saw Eric live a long time ago. At the time of the sound check, the guitar tech played through the amplifier, and I had the opportunity to hear the original sound from the amplifier, but it was completely different from how ordinary people use it.
To be honest, I didn't think it would sound good at all if anyone other than Eric played it, as it was a very muddy sound. The sound was mild and the low range was round.
If you have the opportunity, please try it.
In addition, I, Takafumi Sukuta, am looking for manufacturers and individual builders who can loan me equipment for review videos and creating articles.
