I'll check later, I'm too busy now, but if I'm not wrong it's done because when powered on, pedal is on, with this mod, it will be off - bypass.Ichabod_Crane wrote: ↑18 Mar 2024, 14:35 Change R127 is weird. That is on the switching part. Why change it?

Re: Question on DIY pickup winding. Single String/One Magnet.
Do all pickups have same magnet orientation and winding direction, same amount of turns ?

Re: Question on DIY pickup winding. Single String/One Magnet.
I want to make a switch that can combine the E/A string pickups together and the D/G pickup together so only two signals are going out. I know things get tricky when you're merging two pickups together, so I'm curious what the best way to approach this is. Currently I just have a DPDT switch. Can y...

Re: TI 650859-1 & 650859-3 transistor identification
Maybe that color on the bottom side is code for beta so you can see how much they drifted over time from the specs. Do your transistors have colored bottoms? This letter is from 1966, your part is from 1965 so it could be valid. The paper doesn't mention the TI transistors, so the values may differ....

Re: TI 650859-1 & 650859-3 transistor identification
I guess more info for 650859-1 and 650859-3 can be found in Reference-Book "Wurlitzer Vol. 2" that covers models between 1954 - 1974. Maybe. Maybe not. I've never seen what's inside those guides.

Re: TI 650859-1 & 650859-3 transistor identification
Apparently 650859-3 were also part of the Wurlitzer Organ 4100BD reverb module https://irationaudio.com/2015/03/27/wurlitzer-4100a/ They are Texas Instruments TO5 metal PNP transistors. The number part, as was mentioned on eevblog forum, are Wurlitzer part numbers. https://www.eevblog.com/forum/repa...

Re: 29 pedals - Euna [traced]
2.1V gutshots. On this version the transistor is jfet n-channel BF256b. 6BG smd code corespondes to CMPF4416A. Nearby resistor have different value.

Re: VT BASS DI
There is a thread for Tech21 Character Series, with some schematics and table, but the thread is too long, I can't find quickly where is the one for the VT bass (no DI), if there's one. Nevertheless, this is the thread and the table with some values. https://www.freestompboxes.org/viewtopic.php?p=23...

Re: Digitech Whammy IV issue
Check if this led is working (that's the slot where the plastic strip goes in). If it's ok, you have to go deeper to find the problem. Here's the schematic.

This is the plastic strip that theehman is talking about. And make sure you are connected to the wet output.

Re: Malfunction due to loose wire?
That wire is way too short. It will cause you trouble again. If the connector become loose, it will start spinning and the wire will be exposed to stress and eventually break again. Replace it with somewhat longer one.

Re: Malfunction due to loose wire?
What are the pot values? I guess it's a modded tube screamer, so the values would be 500k, 100k and 20k ?

Well, since the pcb is already out of the box It will be more helpful if you can make photos of the back side too, and all the components that are connected with wires to the board .

It looks like that wire is part of the power supply or the LED, but is hard to tell only from those two photos.

Re: Question on DIY pickup winding. Single String/One Magnet.
So, partially you are aiming at Phil Lesh's (Grateful Dead) Alembic "Mission Control" Quad pickup and some sort of mini wall of sound and the midi part you've mentioned. I don't know what types are neck and bridge PUs, but there are noise canceling coils for a reason. I have no experience ...

Re: Question on DIY pickup winding. Single String/One Magnet.
Just a thought - if there's enough room in the pu cavity, maybe you can try a humbucker (humcanceling) per string configuration. It can be switchable to single coil and have increased output. And have less noise I guess.
