I'd like to mention an excellent article written by Alan Winstanley. Alan has gathered a ton of very well written info on Soldering at this link. I'd like to thank Alan for allowing us to use this link for the benefit of our DIY Pedal Modders. Monte Allums

JRC4558D – Made by Japan Radio Corporation (JRC). Used in the original TS808s and TS9s. Ibanez later changed the chip used in their pedals. The JRC4558D is actually a very inexpensive chip that’s not considered Hi-Fi and was chosen because of its inexpensive cost and not for the tone it produced. It just happened to sound great when used with the Tube Screamers original circuitry. This chip has a little bit smoother gain than the RC4558P which is considered a more Hi-Fi chip. I like the JRC4558D in the SD-1, it's smoother gain in the top end helps to offset the extra hair in the SD-1's gain. I prefer the RC4558P in a Tube Screamer because the Tube Screamer circuit produces a smoother gain and the RC4558P has a little more high end grit than a JRC4558D.

JRC4558DD – Made by Japan Radio Corporation (JRC). This is a Higher Gain & Smoother version of the JRC4558D (notice one has one "D" and the other two "DD"s). It's less Hi-Fi and has a smoother gain structure with a slight rounding off in the highs. This "DD" chip sounds surprisingly good in an SD-1. This is the stock chip you'll find in most SD-1s and TS7s. This is a good match for my SD-808. Try it and I think you'll agree. My SD-808 has clearer top end and more hair. The JRC4558DD tames the SD-808 a bit in the highs. Depending on your amp you might like this chip better. I have a few of these. Contact me if you want one, I don't have these listed for sell on my pedal mods page because most people write them off as being a bad chip. But, who cares what others say, the proof is in the tone and I say they sound great with some SD-1 setups. Of course, YMMV.

RC4558P – Made by Texas Instruments. Also used in the original TS808s and TS9s. Ibanez later changed the chip used in their pedals. The RC4558P is also a very inexpensive chip but considered to be a bit more Hi-Fi than the JRC4558D. It just happened to sound great when used in a Tube Screamer circuit. These are still very popular today and are a great sounding chip. Very similar tone-wise to the JRC4558D, has a little more high end grit.

RC4559P – Made by Texas Instruments. This is a more Hi-Fi lower noise chip than it's brother the RC4558P. The EQ and gain structure is a bit different than the RC4558P. I like this chip because of it's lower noise when used in a GE-7. I also like this chip in a SD-1 and Tube Screamer circuits. This chip changes the EQ of the gain and helps tame the mids in a Tube Screamer.

LP353 - Made by Texas Instruments. Very similar tone-wise to the JRC4558D and RC4558P. Maybe a little less gain but an excellent sounding chip. Subtle differences. This chip sounds excellent in a Tube Screamer, Daddy-O or SD-1. This is a very popular chip with pedal modders.

NE5532 - Made by Texas Instruments. Very similar tone-wise to the JRC4558D and RC4558P. This is a more Hi-Fi, lower noise chip than both the JRC4558D and the RC4558P. I really like the tone and gain of this chip. In some ways I like it better than a JRC4558D or RC4558P. Rich, smooth gain with nice overtones. This is a very popular chip with pedal modders.

TL072 - Made by Texas Instruments. Very similar tone-wise to the JRC4558D and RC4558P. This chip has a very interesting tone. A little more complex than any of the other chips I sell. Very defined harmonics, especially at higher volume. This chip is very Hi-Fi with low noise and a great sounding gain structure.

OPA2134PA – Made by Burr Brown. This is the most expensive opamp chip I sell. This is a very popular chip with audiophiles. It’s low noise and excellent sound properties make it a popular choice with pedal modders. I especially like this chip in a Boss SD-1. It has a little more edge than a JRC4558D or RC4558P and is a tad cleaner with a flatter EQ which makes it a great chip to tame the mids of a Tube Screamer or SD-1. Very rich and defined gain with excellent harmonics and note detail. You can’t go wrong with this chip. Highly recommended.

LM308N – Made by National Semiconductor. If you want that Vintage RAT tone that made the RAT one of the most popular distortion pedals of all time then you'll need to replace the stock raspy sounding OPO7DP. The LM308N will give the circuit a very warm and smooth fat gain struture.

All Chips are shipped with an 8-Pin Chip Socket. We now offer these Favorite Opamp Chips, Burr Brown OPA2134PA, LM308N, CA3080E, RC4558P, RC4559P, JRC4558D, LF353, NE5532, TL072. These Chips will give you a wide variety of tones. NOTICE - Please don't ask us to substitute Opamp Chips in our Mod Kits. Our Mod Kits come with only the chips offered in the kits. We're making these available to those who prefer one chip over another and like to experiment.

I've gotten a lot of requests for these from those that purchase my DIY Pedal Mod kits so I am now offering them as an option to those that want them. These transistors are perfect for use in Ross Clones and Dyna Reissues. They are extremely quiet. These 2SC1849 Transistors have an HFE consistently around 300.

I've gotten a lot of requests for these from those that purchase my DIY Pedal Mod kits so I am now offering them as an option to those that want them. These LEDs are Water Clear and not colored Plastic LEDs like you get at Radio Shack. They are Super Bright and offer a great visual affect. I like to have a different color LED for every pedal so I can tell at-a-glance which effect pedal is being used.

This kit will convert your DC Power Jack to the Boss-Style type DC Power Jack. Kit includes DC Power Jack and Easy-to-follow Instructions.

I've gotten a lot of requests for these. These are 2" x .75" printed black on dull silver. Perfect size to place on your pedals after modding them with my kits. All kits shipped after today will ship with one per each kit ordered. But for those that would like to order extra for pedals you've already modded with our kits we are offering them for sale.
