Boss Bass EQ

Think I'd put it at the end of the chain, unless you have a compressor, then I'd put it right before the compressor. Thing is, you should EQ your sound more by cutting unwanted frequencies than by boosting a lot. The gain you put in at the different frequencies adds up, and as you surmised, can give you a signal thats too hot to handle. What I'd do is boost a little here, and cut a little there, so that the output level of the pedal is about the same whether the pedal is in or out. This is a zero dB gain through the pedal.

You should set the level of all your pedals for zero gain. It's easy if the pedal has a level control. You just A/B it back and forth until the volume is the same either way.

 

OK. It turns out that the Boss Bass EQ has a level control on it that can boost or cut the output 15 dB. Once you have your tone, use this control to get to the zero dB gain discussed above. Here's the web site with a picture and description of the unit.

I'd set it up this way:

Overdrive - EQ - Chorus - Wah - Phaser/Echo/Flanger - Moogerfooger

This is my personal choice however. Having the EQ there in the chain will allow you to change the tone of the distortion, which is then processed by the rest of your effects.

However, I'd say that a lot of those pedals would suck your tone. You don't use them all at once do ya?
