So it is a pedal "ultra gain mosfet fuzz" for guitar and bass manufactured by Arts in Bloodshed which specializes in themed Metal, Stoner, Doom and all effects that are close to or near here far.
Well, as its name suggests, it is a fuzz. There are three knobs at the sides who manage gain, volume and tone (classical ouaipe). There is also a selector of "voicing" that can connect a guitar or bass. The pedal is equipped with 2 outputs, an AC outlet ... and a painting of the mistress of the dungeon with a pair of boobs that will make sense to all your friends. So there is everything you need, no more, no less.
I do not like gas plants, so with 3 knobs and a switch, I'm happy. We get a nice sound 2 times 3 movements. Should be measured very carefully the volume knob if you do not want to squirt blood from his ears. No manual (the one who has ever owned a Big Muff for example do not need). The only point is destabilizing the weird position of the knobs on the sides. It takes more space on the pedalboard but less likely to move settings by snapping or because of a jack lying around.
Yet in the world of fuzz guitar 6 strings and / or 4 strings? Yeah. When you read "ultra mosfet gain fuzz" may be afraid of falling on a modern feel and a little cold with compression ... oh well no. The sound is vintage with low desire and fits perfectly to the stoner doom or very heavy. A big fuzz sound is obtained but with good articulation notes. It should of course play with the amp (I have a Chillbass 200 lamps). It will not happen, however, to get his just slightly colored fuzz. It immediately sends the block. Must spend a little time to get the delicate balance that will big sound with acceptable sound level and tone that pierces the mix. When we found it's great, it buries the Bass Big Muff.
With the guitar, you have a wider range because you can have a mid-gain fuzz up the big fuzz unstructured. The bass is very well preserved and the key is also vintage and rock'n roll. Perfect for Doom, the Stoner, 70s rock but also other grimey styles (Folk Trash, Trash Blues, ...). It will spend less for modern Metal because it does not compress the sound. I do not know if this is due to the Mosfet but the pedal emulates the great white-hot in an old amp Orange or Sunn lamps.
