As lot of us do, I own a recent Ibanez TS9 re-issue (its' about two years old) that I want to convert to TS808 specs. According to some information I've obtained online, all I have to do is swap in a JRC4558D or RC4558 OpAmp chip, change the shunt resistor from 100K to 10K, and change the series resistor from 470 ohms to 100 ohms. Is this all I have to do? It seems rediculously easy for a mod that some folks are charging $45 on up for. Does anyone know the actually reference designators for these two resistors, or are they pretty obvious and easy to find? I would appreciate any advice any of you have out there. Especially if it's in the vernacular of the BOZO, which I speak quite fluently - LOL

Hey Mantas!
Don't have any advice, but, if you are ordering from mouser for anything (last time I checked, smallbear doesn't carry these), order yourself a TLC2272 op amp. I hear a nice diff over the 4558's

P.S. I got that tip from Stephen in an earlier post.

You're right about the resistors.

But they just HAVE to be NOS carbon comp resistors... mkay?

:wink:

Well, I've got my TS9 opened up and I'll be damned If I can be sure of the exact location of these two resistors. Does anyone out there have a picture diagram of where these two little buggers are so I can make sure that I pull and swap out the right ones?

I was pretty sure that these were the two I needed to change. Thanks so much for clarifying this for me. My schematics reading is pretty poopy and I kept running into dead ends whilst Googling.
I socketed my TS9 and put a RC4588P OpAmp chip in it a while back. It made a drastic difference. Now I just want to complete the mod. I'll probably pass on a true bypass mod for a while. I use EMG pick-ups and my present TS9 doesn't seem to be able to suck much tone out of them - LOL.

THanks Again Matt!!! :D:D:D:D:D:D:D

I Bow To YOU!!!

I'm just curious, the true bypass mod you're talking about involves drilling and putting a 3pdt swtich in, right?
