You need this pedal! It has that magic chip?

I have an Ibanez SM9 Super Metal that is my favorite dirt pedal to date. To be fair I have not bought a bunch of them to compare. It had the sound I wanted and along with my DOD American Metal I was good. The SM9 has 2 of the jrc4558 op amps. The Tube Screamer never got dirty enough for my tastes and iirc it only had one of the 4558.
However, googled just for fun....
wikipedia had this (i make no warranty as to accuracy here)
The Ibanez Tube Screamer (TS9/TS808) is a guitar overdrive pedal, made by Ibanez. ... Most TS7 pedals came with the JRC4558D chip, like the TS808 and TS9. TS808HW: In early ... In reality, the type of op-amp has little to do with the sound of the pedal, which is dominated by the diodes in the op-amp's feedback path.

Depending on the circuit, OP amps will change the sound. Same as a tube or transistor. Made by a different manufacturer but same part number, it should not change the sound, but they could meet the specs or totally exceed the specs and still be called a 4558. Then you have 2 boatloads of pin compatable op amps that will plug in and work, some have jfet inputs, some have bipolar transistors, some have mosfets. All sound different.

Some of my transistors are very bipolar too. Really moody sometimes.mozz wrote: ↑Sun Jun 21, 2020 1:12 pm "In reality, the type of op-amp has little to do with the sound of the pedal, which is dominated by the diodes in the op-amp's feedback path."

There's a local guy called Pete's pedals who can do all the analog man style mods to your TS9 to turn it into an 808. I've liked LED clipping both in that demo and the Palisades (which I think is a dual TS circuit with every style clipping imaginable).
