The sound is similar to a vintage fuzz you can get with a tube amplifier, it is good quality and a professional tool. RAT fuzz, you get more distortion on your bass and you keep a nice natural tone from the instrument. Unlike cheaper ones like the Big Muff (seems like it has 2 tracks, 1 for bypassing the tone and another one with a canny fuzz). I use it on heavy rock and songs where the guitars like to go mad, the sound you get is heavier, pronounced and more solid. It works great with other pedal as it include a true bypass, a volume knob (allows also to boost the sound). And mixer knob wich allows you to add the quantity of distortion with another effect. I use a phaser with this pedal wich makes it sound great.

My first impression with the pedal wasn't good, first because of the lack of reviews on it, and the quality of the reviews about the pedal. This pedal is doomed by lack of attention from musician, and people don't want to pay 150$ for a fuzz. However I can say I am very satisfied and it is completely worth it to spend the money for it, that's why I take the time to post this review. The pedal has an "outboard effect" in and out, it has a distortion, volume and tone knob. It has a master volume and a mixing knob. The only thing I hate is that I need to spend extra money to buy an AC extension to plug it.

If you buy a good pedal, you have to LEARN how to use your effect, so you have a learning process that comes with the pedal wich is great as it allows you to "grow" as a musician. Just play around, try different things, play with and without.

One of the rare pedal still made in the US. It is a very good quality. It is heavy (1.5 k.g), it's a tank (be careful, you can use it as a weapon!). Material and crafting is not cheap made. I think it will last 100+ years!

Yes, as I've mentioned, this pedal is good quality . If you want to sound professional, you need professional tools like this one.

I've contact them via email recently and they've replied to me within 2 weeks or so, with every details about the questions I ask for.

I wanted this pedal so much that now I bring it everywhere. I like big vintage pedals (this one is my smallest) and I find it very appropriate in my set. It is a sexy pedal.

Strangely, the Juggernaut Rat doesn't sound nearly as good as regular guitar Rats when used on electric bass. Something is wrong with the gain structure of the unit. The tone is weak. When engaging the on pushbotton it generates a pop so loud it could blow speakers on an amp or a PA.

Components and chassis are solid. More eq would be desireable, as bass distortion requires more frequency shaping than guitar distortion. In and out of the effects loop are mislabled. How could such a mistake be made and not caught before shipping the product?!

Seems solid, but will it ever see the light of a gig?

I've tried units costing half the cost of the Juggernaut that sound better. Should have done my homework before being saddled with it.

We'll seem- my unit immediately went back to ProCo for repairs.
