newbie question - re red llama

[holio cornolio]

Hi,

I'm new to the forum, and come in search of knowledge.
I've built a few fuzz and OD boxes and am sort of familiar with transistor and diode clipping, but I'm about to start building a red llama clone, and looking at the circuit have a few questions..
1: the red llama uses an IC with 6 invertors, but only uses 2 of them. Why? Why not use and ordinary 741 op amp?
2: where's the clipping come from? There's only 1 diode?
3: will a 910K resistor work the same as the 1meg ones in this circuit, and why the big old 330uf smoothing cap?

as you can probably tell, I'm more of a build by numbers kind of guy and have never really questioned what's in a circuit and why, and am wanting to learn.

Thanks for any help

1: the red llama uses an IC with 6 invertors, but only uses 2 of them. Why? Why not use and ordinary 741 op amp?

because opamps clip different(some say in a unmusical way)
so the pedal would sound different(besides, a hex inverter doesnt cost that much, hu?)
which leads me to the next question

2: where's the clipping come from? There's only 1 diode?

the clipping comes from the inverters which are used as amplifiers
the first overdrives the second

3: will a 910K resistor work the same as the 1meg ones in this circuit

yes

thanks. you don't ask the questions you don't get the answers!
