![]() ![]() The trick is knowing where to use that loss to maximise the effect of tone shaping.<< Go turn up ALL the sliders on your graphic EQ and you have max tone but of course it's useless used in that manner,There has to be loss for it to work well. If max power transfer was the game then we would all be using oxygen free copper wire to join the nodes and hang 10 meg resistors off every input,Ker?Ĭricky This is an amplifier not a race car!! I tend to listen carefully when folks have built Real world equipment and are working LIVE players or at least worked a lot with stage equipment. ![]() Again I stress each techno freak has differing views on this but this is my way. ![]() >Sadly the possibilities in electronics is just so vast that what might work in an **ideal perfect text book world** is more often than not, going to have Hi Matt, obviously you are still a bit confused. I don't think we've reached a definitive conclusion. Right, but one of the things postulated here was that an op-amp as a non-inverting amplifier, with some gain, - could have a high enough input impedance on its' own. DrNomis wrote: Well, I reckon you probably will need a buffer of some sort to provide a high enough input impedance for a guitar, the output of a guitar is usually at a high impedance (for passive pickups), a buffer will make the effect sound brighter, personally I think it's good design practice to design for a high input impedance, and a low output impedance anyway. ![]()
