Entirely too much fun

Simply a great pedal. I always keep the mini switch in dry mode. It's great in low blend and sustain settings, for adding overtones, or just fraying your tone a little. And of course it can completely fuzz out if that's what you want. It reacts beautifully with my all-tube amp, and if i switch to the drive channel on my head, it makes a throaty crunch that tapers off into the finer distortion of the muff. The sustain knob is also pretty foot-friendly for rolling your gain in a solo. I never use the normal or bass boost modes for bass, but I have run a guitar through it in normal mode and it sounded really good for anything that calls for an ultra-distorted tone. I have read comments by guitarist that say the normal mode does not sound exactly like the classic big muff, but I wouldn't know. Very good buy, sturdy build, good tone, and pedals don't get much cheaper than this.

Best

I honestly can't believe how much I enjoy this pedal.
The sound is incredible, and my favorite part is that my bottom end stays, I can make it push really hard and keep my low end? LOVE IT!
I personally like the switch in the dry position, so my regular tone comes through but I get that fuzz layer on top of it too.
I have found that if I fuzz out my tone too hard and I don't have that regular bass tone in there too, I get lost in the guitars and their tones.
But with this pedal sound layered in, it just adds the drive I want without compromising my clarity.
I've tried a couple other bass dist. boxes and they all sounded 'meh, whatever' but the moment I started messing with this one, I knew that was what I wanted. I guess this isn't really letting you know what the tone sounds like, but it's so easy to get what you want with it that you need to get one and find out for yourself.

Great Pedal

I use this for my guitar and it sounds great. This has a more fuzzy, warm, low-end sound. Even though the Big Muff Pi USA for guitar is a fuzz pedal, this is a lot more fuzzy. This has less distortion and sustain, though. If you are a guitarist, don't use this as your main distortion. I would highly recommend this.

Bass Big Muff

Im not the best bass player and i dont know everything that i should to make a living in a band. I do know that i was suprised how much you can really do with just one pedal.

Super value

I saw the price and wanted to try it out so I snagged one and so far I'm pretty happy with it. Very simple tone control (yet pretty darn powerful) allows me to get that tone I'm looking for pretty quickly. My favorite feature so far is the dry switch, for some of our music it is great to have the low end really stand out with just a pinch of muff on the the signal. I have a mesa boogie big block 750 that kicks out some nasty distortion and combining the amps distortion, this pedal and my octave pedal equals hours of fun. Fantastic value, super strong construction and easy tone control (true bypass is great to) makes this a great buy. If your looking for some good old fashion muff or an over the top distortion then look no further.
