Now, who the heck would that be???Originally Posted by tot_Ou_tard
The ~10% of that TS technology article that I could understand was extremely interesting. I was stunned to read how incredibly similar all of the various Tube Screamer models actually are. The basic circuit design is the same, with the differences being in a small number of the components used.
For example, consider how the Ibanez TS-9 reissue pedal goes for $100, while the TS-808 reissue will set you back $170. The difference? Well, from what I read, they will almost certainly contain the same "opamp" IC chip, the JRC4558D. So their sum total difference is two (2!) resistors on the output buffer stage, which cost Ibanez less than a penny apiece. Find them on the PCB (many web references available for this) and replace them with the appropriate resistor ratings for the TS-808 and you just saved yourself $70. Better yet, find a good condition used TS-9 on eBay for $70 or so, and you'll save yourself a C-note! Eye-opening, huh?
