Jun 4, Yes, my jcr is: The MC is very old and had poor performance. Consider reading this before posting: Click here to register now.

If you want “vintage Tube Screamer” then this is the best choice probably. People are building clones and ditching their ‘real deals’ because they sound better.

JRC4558 myths…

Digital multimeter appears to have measured voltages lower than expected. How reliable is it? Look 3 small pictures for standard pinouts. Replacement Transformer Started by ncag Today at 7: Are the misinformed still spending 30 bucks or more for a “NOS” chip, and 2 “brown sound” resistors?

It can be replaced by a newer IC that has the same pins but has much better performance.

The Rat2 is the same way. I put this in the same piles as some of the capacitor, resistor and conductor stuff floating around. Jun 3, Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. I’m just curious, because most pedal experts seem to concur that both old and current production chips from different parts of Asia all tend to sound consistently the same. Here is a Datasheet. Some circuits sound better with inferior spec’ed chips.

Sorry to kick over any sacred cows but this is just my opinion based on my experience. We have all gotten used to that noise, so it sounds better.

This is a dual opamp IC, an improved type opamp. Is there any special equalization needed for the preamp or does it neeed a flat response from say 20hz to 20khz Yesall normal types Point for measuring output signal with voltmeter or scope. And, of course, this is because they all meet the same specifications. The in a Tube Screamer does have a sound that is good and is what a lot of people find to their liking.
