Informant Drive tweaks

[Orson Anton Welleson]

I finished the Informant drive over a week ago. It is nice enough, but it didn't grab me. Everything that made the Rat so enjoyable is missing from the ID.

I've heard people talk about trying other op-amps. I think that's my next move. I'm assuming the LM308 would work. The idea being to give the circuit some of the snarl and bite of its progenitor.

Any thoughts from anyone else underwhelmed by the ID?

I'm assuming the LM308 would work.

It won't - the informant has two TL072 dual op amps and a charge pump, the LM308 is a single op amp.

You could try a different dual op-amp but I suspect the difference won't be that big.

If you can identify what it is you don't like and would like more, then you could tweak other parts of the circuit. I wasn't a huge fan either (at least on a strat), I tried kludging in an extra low pass filter in the middle of the circuit (it was too bright on a strat, for my taste), but it didn't work very well. I probably should have put in something before the main circuit itself (although the buffer makes that annoying), since turning the tone control down worked fine for me, but I just sort of gave up on it. Maybe I'll revisit it at some point.
