Electro Harmonix Deluxe Bass Big Muff Pi

This thing is brilliant.

If you're familiar with Electro Harmonix products, then you'll know what to expect - superb build quality and creative functionality. This thing has both in spades, mine has survived beer spills and produced some truly wonderful sounds, live and in the studio.

There's no superfluous controls on here, so it's not needlessly overwhelming. Everything has a very clear function, and will have a massive effect of the sound.

To the sound itself, a massive range is possible. The blend control allows you to be sure that no low-end is sacrificied, which is usually the one main drawback of fuzz effects. I've found the pedal will do pretty much everything from a subtle, dirty overdrive, to a full on wall of stoner fuzz. Hours of fun to be had by slamming out chords.

Engaging the crossover control opens up what is effectively a second fuzz effect (2 in 1, how bad!) and you can adjust the high pass and low pass filters to your heart's content, for an altogether different kind of fuzz. I find this option tends to open up a range of more grinding tones, which wouldn't be out of place in hardcore, death metal, etc. I've used this in a few situations to produce screaming high gain feedback, and other noises. Really with this pedal, your imagination is the limit.

The -10dB switch is a life-safer, as the signal coming off my pedalboard is quite hot, especially when the Big Muff is thrown into the mix. The master volume knob has ample headroom to get you back where you need to be.

This has been well worth the money, and I'm not going to be looking for any other fuzz pedals any time soon, because it just does everything so well. I'd highly recommend testing it out for yourself.

What can I say? You can really dial out anything! When I watched it's demo from EHX, I said, OK, what I'll need is Tone at max, Blend at max, sustain at max, everything at max to get that really thick, booming, aggressive sound I though I'd fancy. Guess what! I was wrong. Even for my extreme metalhead ears, the maximum settings are waaaaay too much :) I didn't like the recommended settings either, so I had to find my tone with it which needed some time, but it was worth it! Juicy little fuzz pedal.

If you are interested in what I use:
Volume at twele o'clock
Blend at four o'clock
Tone at twelve o'clock
Sustain at a little more than three o'clock
Gate at eleven o'clock, but this varies from setup-to-setup, I was relieved to hear that it makes no dominant change in the sound.
Crossover ON:
Both filters at nine o'clock.

But you can really dial out any tone you want. I'd highly recommend this over the standard BigMuff, on the first hand because of the Gate, without it your ears would explode, because it brings through a lots of noise...but a friend of mine explained, that to get the exotic Muff sound, it has to be nosiy...and on the second hand, because of the crossover section. It increases your tonal possibilities, but can be disabled if you don't need it. Very useful.

I'm not sure exactly what I was expecting, but this pedal blew me away! I've been using a multi-fx pedal with a Muff-style fuzz but having the real thing is just so much different.

this pedal has so much body and muscle to it, and it sounds just super tough. the fuzz itself can vary from a little distortion to full out fuzz - and with the blend knob, you can keep however much dry signal you want. personally I like it at 1/2 o'clock, with just enough clean bass to fill out the low-end. the gate is also super handy, gets rid of any unwanted noise with a simple turn of the knob, and works really well

this is all without talking about the 'crossover' feature, which basically makes this a 2-in-1 pedal. there are even more different sounds you can get from this function with the hi-pass and low-pass filters (where the HPF affects fuzz only and LPF affects dry signal only)

I do not believe I have any cons with this pedal, though with time I'll get to know it better

all in all a very, very good pedal and it's for sure a keeper :)

I will just start with what blows me away most; the sounds. There is a lot of tone control with this pedal. You can have just a hint of fuzz, full on fuzz, or even sound like a 70's distorted guitar. This pedal is just unbelievable with the potential of sounds coming from this. Best part? Activating the bypass and/or the crossover makes no "pop" like some of the cheaper pedals on the market.
When I opened the box, I didn't realize the actual size of it until I held it in my hands. It is about twice the width of a wah pedal but the casing is pure METAL. I honestly believe that I could hit it with a hammer and only make a minor dent in it with no damage to the circuit board inside. My guess is that it is made out of 16 gauge steel. Bottom line is that this pedal feels road-worthy and durable.
All in all, I recommend this pedal to every bassist out there. If you're willing to drop money on the Big Muff Pi, get the deluxe. It is just better.

Having messed around with multiple amps, fuzz/distortion pedals for year on the Bass, this just does the job in one box. If you love the big muff sound then its all there, but the real show stopper is the crossover function. This basically negates the need for two amps in creating a proper bass fuzz sound. The cross has low pass and high pass filter (adjustable) that replicates splitting the sound to two amps. The top end is fuzzed and the bottom end is clean.
If anyone is frustrated by "blended" bass overdrive pedals sounding like a clean and dirty basses playing together this pedal solves the problem.
If you like the blended sound then that's there as well.

Simply awesome pedal. If I had this 30 years ago, you would know my name :D
