How to turn this RM400++ pedal (Ibanez Tubescreamer TS9)
TO this pedal (Ibanez Tubescreamer TS808)

Price at Bentley Rm600++



Ibanez has re-issued the original TS808. In reality this is a waste of money. You pay RM600++ for a vintage look. You can get the same tone of the expensive TS808 by modifying his brother, TS-9. These can be had for i think around RM400++ at Bentley music. Mind the '++' symbol okay.. heheh..

Let's take a look at the heart of the Tubescreamer. The main component for the TS808 tone is the chip. There are several that work. Two different chips were found in the orignal. The JRC4558d, and the Malaysian chip RC4558p. The big difference between the two chips is the JRC has more gain. the RC4558p doesn't have the grit the JRC chip has, but it does not produce as much noise.



The last two parts you need are two resistors. They are 10k ohm, and 100 ohm resistors. These can be found in just about any common electronics store. (ie. Radio Shack)

Now let's get into where to put these parts.



Here is a recommended list of parts needed to perform this mod to your TS-9.

JRC4558d or RC4558p opamp chip 100ohm resistor 10Kohm resistor 8 pin chip socket (recommended if you want to try different chips!) Solder De-soldering braid Remove the battery cover and battery. Remove the back cover by removing the four screws. Remove the single screw holding the circuit board in place and carefully flip the circuit board over so the parts are visible.

Locate the square black chip with eight pins - marked "A" in the picture. This is the op-amp chip. Look on the other side of the circuit board and locate the eight pins of this part. Mark them if necessary. Remove the solder from these pins (one at a time) by placing the braid on the pin and pressing the tip of the hot soldering iron directly on it. In a few seconds the solder will melt and the braid will absorb it. (For best results use a pencil-type soldering iron rated at 15-30 watts).

Once the solder is removed from all eight pins, remove the chip. You may have to use a paperclip or something similar to slip under the chip and lift while touching the pins on the other side. Once the chip is removed, install the chip socket into the board and solder all eight pins. It doesn’t matter which way the socket is turned.

NOTE: Static electricity can damage the op-amp chip. To be safe, touch something metal before handling it.

Now gently insert the JRC4558d, or RC4558p chip into the socket, making sure it is turned to the position as in the picture. If the chip is installed backwards or upside-down damage to the chip may occur.

Refer to the picture to locate resistor "B". It is a 470-ohm resistor (with color bands yellow-purple-brown-gold). Remove it using the same method used to remove the op-amp. In it’s place install the 100-ohm resistor (brown-black-brown-gold).

Now locate resistor "C". It is a 100k-ohm resistor (brown-black-yellow-gold). Replace it with the 10k-ohm resistor (brown-black-orange-gold).

Carefully put the circuit board back into place fasten it with the single screw, replace the back panel, and install the battery. Your tubescreamer is now modded to TS-808 specs! Plug in your favorite guitar and make sure it works properly.

If you have any questions, or would like some help with your modifications feel free to email Kevin@Tone-Jam.com.

Keep on Rockin!!

i already modded my TS-9 kau kau Very Happy

IF anyone stay near SEri hartamas..
IF u get the opamp and resistor.. i can mod for u for free
if u got nothing.... i mod for u for 10 ringgit


JRC4558 / RC4558 opamp
10K -- carbon film, 1/4 resistor for 808 mod
100ohm-- carbon film, 1/4 resistor for 808 mod
-------------
my own mod.. better craps for ts-9

replace tantalum tone caps with Poly film caps (o.22mfd/ 35v)---for smoother tone
replace the cheap 1uf non- polar change to 1uf metal film.
replace .047uf to metal film .1uf for more bass
replace the LED to 5mm ultra brightness blue/water clear LED
replace 10uf@16v electro with 10uf@25v tantalum cap
replace 510k input resistor with 620k - 750k resistor

wei cayalah ..byk nya ko tukar? tolong kasi info pasal functionnya :


1. replace the cheap 1uf non- polar change to 1uf metal film
2. replace 10uf@16v electro with 10uf@25v tantalum cap
3. replace 510k input resistor with 620k - 750k resistor


aku gian ni.. tolong kasi sound clips la..

you can order it here:

here's another cheaper option, but must purchase at least 2 switches! total is about RM56 for a pair of 3PDT switches (includes shipping cost)...

i saw a few more on the web, forgot the link, i'll update later...
