Build Your Own Clone Message Board

Well I stopped by my local electronics supply store yesterday and picked up a spdt toggle, some additional diodes, and a handful of LED's and I am ready to mod my screamer. In looking at Kahel's diagram and the parts, I can generally get the idea, but I have a couple of questions...Do you simply twist the leads for both the diodes and the LED's together for the side opposite the toggle and wire a lead to the bundle? Also, does it matter which way the LED's go in terms of cathode, etc? If so, which way is correct? Thanks bros. I promise this is my last stupid question...today.

This is what I did:





Yes, direction of cathodes do matter... just make sure they are in opposite direction of each other.

Thanks Tone. Your input is very much appreciated. Off to the lab....

Does the yellow LEDs in the landgraff light up?? strobe?? are the bright??

It is!!!

They do not light up.

Oh, that sucks. Supposedly, the red ones that Dano did for the Rat clone do light up.. but I think the pedal is driving them a little harder than the TS808 does.

I did this mod to my BYOC screamer and they most certainly DO light up. I used 5mm yellow LED's and they light up clear as day depending on how hard you play.

Do you have a name & model number on those?

And: Do they sound good?

K

Mine sound great but they don't light up...

I've tried yellow 3mm and red 5mm... neither of which lite up for me.

yes but which one sounds better?

sorry i took so long kahel!

They are Xicon 5mm diffused yellow LED's... I got them from mouser they weren't hard to find. They sound awesome! I prefer the 2 of them to the 3 914 diode "marshall" option. The LED's are louder and just sound fatter to me? The 914's are noticeably quieter and less fat. this is just my opinion though...

Kahel
I wanted to ask you something....I did the "fat" pot mod to my 808 and it doesn't seem to make a huge difference. Am I right...is this a "fine tune" kind of thing or should I really notice a huge difference? Thanks!

A Mouser product number...? I'd like to see a datasheet on those.



It's meant to be a fine tuning of bass response at high gain settings I believe. I admit my screamer is still not finished and I haven't tried it myself, but you should head a difference in "muddiness" at high gain. If not, we might have to look at the values again.

K

The "marshall" option you are referring to is the LEDs... the 3 N914's are the TS808 mode. This is, of course, if you are referencing the toggle positions of the Landgraff DO.

the mouser part number is 351-5302-RC enjoy!

We may need to tweak the values of the FAT pot mod...it's very mild as is.

tonefreak- thanks for helping me out with the abunai info.

Does the direction of the LED's matter? From Kahel's diagram, I am guessing they are situated in opposite direction to each other too. Is that right? Thanks.

Direction does matter... you are correct, the need to be oriented in the opposite direction of each other.

Have fun!

i am still wondering when we decided that stock ts-808's used three 1N914's all of a sudden? i'ts always been two. look at a schematic:

don't know where this information came from... :-|

I've been using the 2 1N400's and 1 1N914 and will use that with 2 yellow LED's, and the Mighty Mouse Mosfet/Diode as a 3way clipping choice.

Hey relax. Nobody said "stock" meant Ibanez factory spec. It came from the handwritten schematic of the Landgraff, where one mode was called "Marshall" and the other mode "Stock". I just used the same names in the diagram.

K

ok, so the landgraff actually uses the 3 914's. i was wondering where it came from.

someone should try clipping diodes from pad D2(or the second drive lug) to Vref. disconnect all the other clipping diodes first. if i'm looking at the PCB traces correctly there should be an unused pad and hole for Vref that is there for technical purposes.

it works, i've done it but i didn't get to experiment that much with types of diodes etc. i think its a much fuller alternative to clipping in the feedback loop though.

That's what he calls the "TS808" mode, but you are correct in saying that a traditional TS808 only has two.

I'll have to give this one a try then. Have you tested it with a series pot en route? Clipping on a tap...

K

i've been wanting to do alot of research on it but haven't had the time. that was one of the things to try though. it is a bit harder clipping, and leds do light up there.
