Maxon Apex 808

[Andrea Joy]

You can try different ICs to find the tone you want. Here is a list of IC chips I tested; you can also do your own search and try every standard dual op-amp IC you like:


JRC4558D (current production) - classic TS chip, follow-up of the original IC, smoother than the RC4558P

JRC4558DD - high gain version of the classic chip

RC4558P - made by Texas Instruments, sounds warm and soft, but rawer than the current production JRC4558D. Robert Keeley´s first choice, also my favorite IC for Tube Screamers

RC4558 (generic) - no-name clone of the TI RC4558, sounds edgier than the original

RC4559 - high-performance dual opamp, used in many quality audio preamps

LM833N - low noise dual opamp, known to sound good in TS circuits

MC1458 - low noise, soundwise somewhere in between the JRC4558D and the TI RC4558P

TL072 - used in a variety of commercial TS clones

TL072IP - Low noise version of the TL072, more hi-fi sounding

TLC2272 - increased dynamic range, high drive

NE5532AB - audio opamp, low distortion, high slew rate

NE5532AP - audio opamp, very low distortion, high slew rate

Burr Brown 2134 and 2234 - audiophile audio opamps, very clean and transparent

Manche von den Bauteilen kosten ja überhaupt nix.
Vielleicht ein Projekt für den Winter...
