I have it at the end of my signal chain to "warm up" my solid state amp
I place my jekyll & hyde overdrive in front of this pedal to boost it, also my ibanez ts-7.I've tried using this pedal as an overdrive with my amps, I used a solid state amp and the blues
Personally, this pedal played with my mustang V solid state amp just make it sound unbelievably good
I get comments about my tone all the time, and most people can't believe I'm using a solid state amp with a chinese made tube modeling pedal
I have a solid state Fender amp (Champion 100W) with on board modelling
If you are looking to get a good octavix/Octavia type effect in this pedal, you may want to reconsider(MHO)...
I tested the sound with a Yamaha nylon silent guitar, directly plugged into my recording interface, which probably isn't what most people would use, but I hope that the effect is nevertheless easy to gauge by ear as I go through different settings in my video
For the price, this guy puts out a pretty good range of fuzz, and the octave up effect is decent for high and high-mid ranges
Also, these have two capacitors on the PCB which were soldered backwards (their polarities are reversed) and if you take the time to switch them around you'll get a much better effect
The JF-12 fulfilled the purpose with relatively clean boost, decent overdrive, great fuzz, and a reasonable octave generator effect
Look up videos of this before you buy it, if you find that it has the sound that you are looking for by all means buy it it is very well built and well priced
It is extremely well built, and have had zero problems with it during that time
There are some A/B blind test on you tube and is really hard to tell what is what
The pedal is very well built and decorated, it is rugged, the pots rotate very smoothly, and the sound is warm and transparent
The pedal is solid, well built, and sounds better in terms of audio quality than the Boss pedals I have owned
The overall tone was lacking, I sent this pedal back for a refund.
I was missing the tone I used to get out of some of my older Peavey amps, and this pedal brought it back -- but with a decidely Fender-like sparkle to it
But it does make the clean tone in the crate very tasty
Aside from poor packing job, and power issue, this pedal sucks tone like crazy when the Octave Up is active
I love stacking this on top of the Big Muff Pi to create this massively loud fuzz tone
There are some A/B blind test on you tube and is really hard to tell what is what
My only gripe would be that the footswith could feel of better quality however everything works as it should
Don't know yet how it works as it did not come with a cord....
I've used it in front of solid-state and tube amps alike, as well as in a direct recording setup, and have been pleased with my tone in every instance
Great toneTHe fuzz on this is alrightThe octave switch is useful for getting interesting effects and for creating a dirtier soundThe mid cut is nice to havecons:lots of noise from the pedalthe pedal has horrible feedback, worse than when I am using a blues driver and a standard distortion pedal at the same timeThis pedal is good if you like getting lots of feedback (my band actually uses this to get feedback to end/begin some songs haha
