Op amp questionaire!!!
Posted: 20 Jun 2009, 16:13
Okay I know the great people of this site are well capable of helping my latest question.
Who can explain the differences in the most common Op amps and the most common Op amp replacements.
For example I know some places swear that the 4885 is the perfect replacement in your new distortion or overdrive pedal. I have heard the newer Op amps with long number and letter names are more hi fi and better suited.
I have also come across that because the less clean and easier some op amps are the more you would be drawn to place that specific one in the circuit.
The main reason behind my question is a Metal Zone mod. It got me thinking more about the op amps ... the one I am modding has three (mitsu) op amps and I also discovered that Boss has produced 3 versions of the MT-2 and each had a different combination of the three.
I am very interested in the socket that allows you to replace your sinlge inline 8 pin and plug and unplu instead of solder and desolder!!! Great idea by the way ... I would love to start mixing and matching the dual inline pin op amps ... I saw a small board that allows you to place to opamps together and then the board will drop right into the single inline slot. I think Monte Allums offers one of these set ups and I am sure that mouser and other elec suppliers do also.
I know I will have do a little bit of spec research also to know what will and will not work together ... I know some have the 7 pin is hot and the 9 pin if not and then a different op amp is completely backwards.
SO THE QUESTION AT HAND IS : WHAT CHARACTERISTICS CAN BE HEARD FROM THE MOST COMMON OP AMPS AND THE MOST COMMON OP AMP REPLACEMENTS. EXAMPLE : BURR BROWNS DO THEY REALLY ACHIEVE A BETTER TONE THAN THE STOCK TS-9 CHIP? I UNDERSTAND DIFFERENTAPPLICATIONS WILL PRODUCE A SLIGHTLY DIFFERENT OUTCOME SO AGAIN I AM WORKING WITH BOSS PEDALS ONLY FOR RIGHT NOW. THANK YOU ALL SO MUCH!!!!!!!!
