Question 1

"a genuine analogy delay with new cd2399gp(pt2399) ic installed." this is some weird advertising. its a digital delay? not analog?

Accepted Answer

i opened up my og yellow fall and  looked up the data sheet for the chip.  It's a cool little chip from a chinese company, it's basically a hybrid design/mixed signal design.

the new chip is obviously inspired by the old panasonic/matsushita chips that electro harmonix used in the 90s, but the main difference is, the matsushita chip sampled to an array of capacitors and this thing samples to an array of 24-bit registers

the sample clock is an analog multivibrator (same as an og memory man, etc).

this type of design is colloquially referred to as a "bucket-brigade" delay.  in either the og matsushita, or this new chinese chip, the samples are shifted through each register, similar to the way a line (bucket-brigade) of fire fighters would have passed buckets of water from a well to a burning house in olden times.

i used to own a 90s deluxe memory man, and i really prefer the tone of a stock yellow fall to a stock 90s dx mem-man.

the 90s dx memory man leveraged a compander circuit to process the signal in and out of the matsushita.  This could be quite a tone suck, and the pedal wasn't true-bypass.
the stock chips in the EH were dirt cheap op-amps, but they could easily be tuned and/or replaced with precision op-amps, which could vastly improve the perceived dynamic range of the pedal.  (try to pick up a 90s dx mem-man if you like to mod pedals, it's a modder's dream!)

This new chinese chip does not suffer from any of those problems, because, of course, 24-bit registers can sample a very respectable dynamic range, and everything is true-bypass, these days.

all in all, i would say that the yellow fall is a modern classic!  Everybody should have one!

I just wish Donner would make a Deluxe YF with tap tempo and expression pedal/CV sync input and sample to 32bit floating point registers with a pot to control the sample precision (to add a bit-crusher effect)!  that would be my DREEEAM delay pedal!!!!

I hope my long-winded answer was helpful to understanding these things!

Question 2

Does the package include a 9V power cable?

Accepted Answer

Thanks for your questionNot，there is no power cable included,only a guitar pedal!

Question 3

anyone compare this to the behringer compressor?

Accepted Answer

I haven't compared this to the Behringer compressor but I have compared it to a MXR Dyna comp. The Behringer pedals I've had sounded good but were not very well made and crapped out on me after not much use. The Donner is a well built pedal and has a wide range of compression for the price. It is also a pretty quiet compressor compared to the Dyna Comp. I have a few of the smaller footprint pedals (Moore and Ibanez) and this one is built like a tank. For $40 it is a good purchase.
