Hello all! Im building an effects pedal for my guitar (dont have a choice, I spent all the money I was saving on the guitar). Since electronic components are cheap, for once, Im glad Im studying EE. At first I thought I'd design the circuits myself, but after doing a bit of research, I found a load of schematics available on whatever effects pedal I want, I do have a couple of questions though... Ive used 741c op amps in all my practicals and Im familiar with them, however, can I use the 741C instead of T-1215 op amp? Also is it absolutely necessary that I use the te series capacitors when required or will standard electrolytic ones suffice?
