Wow. I used mine happily with quiet passive basses and really hot active basses. The gain works just fine.

Sorry you had such a bad experience.

 

Yeah, the gain wasn't a really a problem on mine, and not a volume drop other than certain settings: 

 

"I think for the Band Pass has some decent sounds if Range is set 'low', but for me the gain needs to be low to get a decent sound with the drive set 'up' - meaning the output is quiet. Drive 'down' can sound good if peak is set low and gain high, then it has a decent volume and nice squish, clean blend with it would be useful though."

If it's anything like my my old original Musitronics Mutron III it inverts the phase, so a clean blend can actually make things worse, unless you have something like the Xotic X-Blender that has a polarity switch to flip it back again!

Trump sticks 104% tariffs on them, Uli Behringer shrugs.
Quatschmacher gives a bad review... product gets pulled.

...and there's me thinking it might be a copyright thing 😉 LOL

Nah, it was 100% gone, so it's been put back.

 

Interesting.

Hi - I ordered one, in part because I also got the Brass Master fuzz and loved it. I agree with everything said above, on the low pass mode it is a very useful and responsive pedal. However the other two modes seem to involve quite an extreme volume drop no matter what I do with the other settings, so perhaps as people seem to indicate above this is a quirk of the original circuitry rather than a fault. 

 

Ironically the Brass Master has the opposite problem - a really big volume increase even with the gain turned down and no master volume - and so I bought a stand alone volume pedal to use in conjunction with it, so perhaps I can use the same pedal with the  B Tron (though of course it is an extra faff).

The low pass is the only suitable one for bass. On any filter.

Hm it's usually the best unless you're blending in some clean, in which case Band Pass can work really well too. But on the original Mutron, LP was the only mode that sounded good with bass.

Once upon a time I would have agreed with you, but the MXR Bass Envelope Filter is band pass (with dry volume and FX volume knobs) and it is glorious.

I’m pretty sure Bootsy also uses band pass on some of the parts on the Parliament stuff, certainly sounds like it in places.

Yeah maybe - I think I didn't really use it because there was no easy way to blend in clean. Just another way the meatball improved on the design imo

Mike Beigel’s Q-Tron and 3X also improved this by adding the “mix” setting which is a fixed blend of BP and dry. The MXR BEF has a dry blend and this along with the voicing of the BP filter makes it great.

Somehow I didn't like the mix setting on the Qtron, and I found the voicing on the BEF was 100% better turned to zero as I really didn't like the vowel like character as you turned the dial... great pedal otherwise though.

Do you mean the Q or the Decay setting? I have my Q set at about 10-11 o’clock.

Ok. I should have added the caveat that without a dry mix the low pass is the only suitable setting for bass.
