how bad infact is the woolly mammoth with a jazz bass with EMGs? i dint have onboard eq, just the pick ups and theres a tone nob. thanks
IMO it sounded horrible with active electronics. Usually I dig weird sounds but Mammoth just sounded weird in a bad way. Imagine extremely compressed low frequency drill. With passive electronics Mammoth is excellent. I have jazz bass with J-retro and Mammoth works fine when preamp is bypassed.
i would go one step further and say it sounded bad with high output passive like my gibson ebo. that huge humbucker put out too much signal for the mammoth. sounded much better with fender p or the rick 4001
Sounds horrible with active. Its ironic that the best sounding fuzz pedal only sounds good with low output passive basses, which are not exactly what companies are pumping out these days. I do have to say i love this pedal. Luckily my F bass has passive mode so i can enjoy it!
The basses with the active/passive things don't work either. I had a Mammoth with a Warwick Infinity SN and it still sounded bad.
Are you 100% it's a true active/passive switch? On my thumb, IIRC all the switch did was bypass the eq section of the preamp.
I have J-retro preamp and when it is switched off mammoth sounds really good but when active electronics is on the fuzz is horrible.
Easiest way to check if it's truly switching to passive is to take the battery out of your bass and see if you still get a sound from the amp. If it's truly passive, you should still get a signal. Cheers, Alun
