DVM's Zonkin Yellow Screamer pedal

[Tone2TheBone]

I'm digging the Texas Instruments 4558 in mine. It seems more high fidelity to me. I can't get over the amount of gain the Zonkin' produces. My favorite position is normal on the mini toggle and I'm usually on the upper end of choices on the gain/bass boost. Positions 4 and 5 mostly.

In relative numbers, the max. gain for a stock TS-808 is 118. The ZYS max. gain is 110 on the "normal" gain settings (rotary positions 1 - 3), and 511 on the high gain settings (positions 4 - 6). That's 4.3 times as much available gain as the stock 808. R

Oh yeah it's awesome. I remember asking you to make mine better than the BM and well yeah it blew it out of the water in terms of hifi tone and gain.

What about the Banshee...I dont have that option, huh?

Nope. You've got 118, period. Same as the TS-808.

Yeah, that's a good one. The RP4558P is the opamp that Robert Keeley uses in his upgraded TS models, the best known probably being his "baked TS-9" mod. Until I obtained the TI TLC2272ACP, the RP4558P and it's "1st cuz", the RP4559P were pretty much a toss-up as my favorite TS opamps. I like their smoothness, too, Robert.

Will be interested to see what you think of the LM833N....

The Texas Instrument opamp I'm using right now IS THIS chip right? It's in my pedal now so I can't see it. Tell us here what benefits the LM833N would offer?

Not unless you bought it yourself. I didn't find the TLC2272ACP until after I bought the opamps for the four ZYS production run.

The four opamps that each of you received were:

• JRC4558D (original spec TS-808 chip)
• TI RC4558P (used in several boutique TS clones)
• TI TL072IP (very popular TI opamp)
• STM LM833N (low noise)

As indicated, the LM833N is a low noise opamp that is particularly suited to high gain applications. So when you crank the gain/bass rotary over to positions 4, 5 & 6, it should reduce some of the background noise and maintain note clarity a bit better.

Well then where did Robert get RP from! Did he typo or did he buy one?

 

[Robert]

There's a typo somewhere... TI RC4558P or TI RP4558P?

I only have the chips DVM sent me.

Ok then it was a typo. We both should have the TI RC4558P...not a TI RP. I was just wondering if you got something different than what I got. Thanks for clarifying man.

 

[duhvoodooman]

Yes, it's the TI RC4558P. I didn't catch that typo further up the page, and repeated it myself. It kind of gets to be "alphabet soup" with all these different opamp designations after awhile!

"Alphabet Soup" - sounds like the name of the next great voodoo pedal!

TI RC4558P is the opamp that Im currently using, that Id previously refered to as the boutique...my observations with this one is that its more of a plain ol boost, doesnt seem to add much crunch or grit...just boost.

For some reason I thought I had 2 more to try, guess its the TI TL072 next...I'll probably install it later this afternoon.

Tried the TI TL072 this week...Id say its pretty clean and jazzy...Im going back through the opamp rotation and starting over again with the one that came in it(JRC4558D)...but its a toss up between that one and the TI RC4559P for me.
