King of fuzz
Once i started looking into pedals as a beginner, one name kept coming up over and over and it was the big muff. Wasnt sure which one to go for so went big and got the deluxe and it doesnt disappoint. Perfect for stoner bass riffs
Amazing pedal !
This pedal is really the one I was looking for. The sound is very nice and versatile, the pedal is easy to handle and the extra features like the direct out and gate come in very handy.
No warranty for me, instructions in german
Because the instructions were in german , i did not notice i had 10 days only to register the product. i wonderr if im not gonna send it back to buy a new one somewhere else and have my warranty.
I will never buy electro harmonix ever again , i have two pedals from them,
I also got an overlord from somewhere else at the same time.
Instructions in german and both pedals now have no chance to get a warranty.
Should i just learn to fix pedal myself?
A ridiculous company that give you a week to register when the product takes 4 day to arrive (if not five).
The 10 days are from the purchase so if it takes 2 weeks to arrive you wont even have a chance to register it.
Never been so disgasted to give buisness to someone.
Ridiculous ridiculous ridiculous
I can hardly rate it as it suppose to work for bass and guitar alike but without manual im not even sure if you should change something .
It doesnt sound amazing right now and some features are losing sound on bass and i cant figure out why .
After all the good comment i ve seen on this item i was over confident of it been good.
No one talks about the warranty rip off
great fuzz
easy to use yet versatile, and has a great sound, get it and have some fuzz fun.
so many features at such an affordable price
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 :)
