Since i'm not sure, what's the maximum voltage that this chip can handle(single supply voltage)?. Is is safe @ 15V? :scratch:

How will you know if an IC is functioning or not using a DMM? Are there any ways on how to check it?

Has anyone seen any examples of op amps in distortion boxes being damaged so that they sound bad but still amplify? I have a Boss Distortion that I put the Keeley Seeing Eye mods into, but now it sounds very splatty. I triple checked the mods and checked voltages, but everything looks OK. It would be nice to get opinions from any of you before I try to skywire a DIP8 in place of that inline op amp. Thanks!!

Basically I have made a tremolo LFO that uses an optoisolator to make the resistance across two pins increase and decrease in time with the LFO.

What I need is the option to let the increasing resistance either increase or decrease the volume of an opamp. The reason why I need this is that in a stereo tremolo, you either want the two channels to do have the same curve or you want the channels to have inverted curves.

Is there an easy way to toggle between these two things with a switch? Maybe...

I have the dod fx35 octaver. I didn't use it for ages, but recently I noticed that it could be useful for a certain sound, compared to what can I get out of my (vintage) bass-whammy.

The schematic (not sure if it's _really_really_ correct to the actual circuit):

But the dod octaver has some noise floor. Question is what could I expect by replacing the 1458 opamps with say tl072? Or tlc2272. From what I saw in the diagram, imo these opamps could be replaced without any further ado. (Plus the...

Found this the other day

Don't know what to hear/think
:D

Hi Guys
I'm not really into ICs, but lately I've been working with some modulation designs (phaser, flanger, tremolos), and I wonder if there are any really good opions for the following:

1) Amplifiers for the phaser shifting section

2) ocilation section

I'd be specially looking for quad opamps to handle both this sections, but if the best case for number 1 be different than best case for number 2 I'll be willing to use the different options in the same project. I hope I make it clear in...

I picked up a bunch of these chips to try them out since I read the thread about them and I'm ready to put them to work.

Does anyone have any suggestions as to what circuit these would sound good in? SoS? FullClone?

Thanks!

Question here for the board;
Anyone know whether the MAX 1044 when used as a charge-pump, does it eat 9V batteries quickly or is it similar to normal battery consumption in any given circuit?

can someone tell me the difference between the TL072 and the TL062??

the fact is that i'm modding a bit my Boss Flanger and i wanna change the 2 4558. i know a guy that as putted in a TL072 for IC1 and a TL062 for IC2.

What's the difference?

also i was thinking about 2 NE5532 instead, will those also work? do you think this is a better choise?

thank you
