would that affect the tone at all? same tone, just with the interaction abilities of a passive bass?

Still doomy as hell.

That last part sounds weird.

I mean bands like Antestor who are Christian with corpse paint. Like Black Metal look and all but with songs promoting the religion rather than being against it.

That actually looks fairly simple to build. Kinda wish we had thought of this before i sold the EMG's in my p-bass...

That I could not answer definitively, if designed properly a buffer should not affect tone, so it shouldn't, but we wouldn't know until we built one.

well it will affect the sound. Adding in the series resistance will interact with the proceeding stage whether it be an amp or pedal. thats why you need to do some kind cap bypassing and what not to balance out the high end loading with the overall loading. It takes some experimenting to work but it should balance your sound to be more passive.

nice thing is u could build that on turrets, no sweat. If people here are interested in something like that, I would be willing to build them

Well, I don't know how to read your moon writings, but I sure would want to try one with my active traben lol.

[dunwichamps]

i do have some spare board hanging around which was a misorder on corey's preamp. if someone wants to pony up the parts. I could build it

i think i would probably also add an inductor in series with the pot and put the cap to ground instead.

A random thought, since this would go at the front of an effects chain, and with the rising popularity why not include an adjustable HPF in it as well? It would basically be a signal conditioner for active basses for those who use alot of pedals.

Lots of the classic doom bands had christian themes. Sabbath and Pentagram come to mind (After Forever, and Review Your Choices)

Version 2 Active to Passive box, tailor the inductance and cap values to dictate the mid range and high end response you feel is more natural with passive pups

hahaha i love this idea, and instead of x-mas we celebrate Tony Iommi's birthday. Can you imagine the patron saints as well?

Tony Iommi - Our Lord and Father of the Riff
Matt Pike - Patron saint of Shredding
Al Cisneros - Patron Saint of all that Rumbles
Stephen O'Malley + Greg Anderson - Twin Patron Saints of Volume
etc, etc

sooo.... how would you know which way to go with it to make it work for a particular bass? would you just need to know the output specs of it? or?

and the "cap bypassing", is that something you need to do in the bass preamp, or in the "passive" pedal... again, sorry....i'm an electrical idiot. I only know enough to know what not to do to get killed, or blow up my amps.

i actually changed it to treble shunt. So you need an inductor and a cap to emulate the mid range and high end response of passive pups so you just need to tailor those to the passive specs you want. For example you could put a mid range hump around 1k and a 3 db treble cutoff at 4 khz if you wanted. Depends on the desired response.

So yes you would need to know some kind of specs on what you wanted or just experiment til ur happy.

Hmmmm this is a tough one, i was reserving the god spot for Iommi, as he is the true "father of the riff" IMO. Lemmy would be the god of rocking the fvck out, it is well known nobody rocks as hard as him.

Wouldnt the basses onboard preamp still affect the overall tone? Allowing you to compensate for any frequencies lost in the pedal? (presuming it doesnt cause like a 20db in the high end or something like that) Still allowing your normal tone to come through with some minor tweaking?

Impulse purchased Vincebus Eruptum by Blue Cheer on vinyl during lunch today. I'm not a huge Blue Cheer fan, but that should definitely be a good listen when I'm stoned.
