Mic and DI, but use the mic for the tone and the DI for low end on massive PA's.

Don't care, as long as the soundguy makes it sound good.

no posts in this thread for a while.
got a question ( for timi ,probably my best bet.) ,now that i am using a couple of fuzzes .
have you ever ran a d.i. with fuzz? i'm a bit concerned about the horns of a p.a. sounding to harsh .

In my opinion any overdrive, distortion or fuzz run straight into a DI sounds like crap. Lots of harsh top end that next to no live console can remove without taking away all your top end since they just have shelving eq's for the treble. To try to simulate a speaker to smooth the top end out you need to use a LPF eq, and one with a very steep rolloff (18dB per oct), which as I said hardly any consoles can do, and even if they did would you really trust the soundguy to do this....

Easiest way to get a good drive sound into a DI is to use a simple speaker sim, which for some reason isn't as easy to come by as you think. There is a red Behringer DI that has a speaker sim (based on a guitar 4x12 cab), but I don't know how good this sounds and I would rather not use a Behringer DI...

I use a Digitech Bad Monkey at the end of my chain which has two outputs, one of which has a speaker sim and works even when the pedal is bypassed. The sim is also based on a guitar 4x12, but all it really does is smooth off the high end, a sharp LPF around 3.5k to get rid of the harshness but a slight boost around 2.5-3k to give some clarity since most of the freqencies above that are gone.

Thanks timi. low pass filters are easy to make
just worked via this site http://www.muzique.com/schem/filter.htm

...that if i use a 250k pot and a 0.18uf cap i can pass below 3.5386 khz
do you think that would work well enough?

It doesn't say the dB per ocatve slope for that though, its probably more like 9dB per oct but you really need to be around 18dB.
I'm sure theres an easy circuit to do this if you hunt around.

yeah thats just frequency calculator . been searching for a while to no avail .
why would you need 18 db.
do you know how much a passive bass knob cuts?

I don't know much about passive tone controls, except that the impedence from the output of pedals makes them behave differently to when they are straight out of the bass.
