Jimi Hendrix 70th Anniversary Crybaby Wah....

hi,

is there someone with a bit of imformation about this TVP-1 ?

I have to fix one (lfo isn't working, or the CMOS switching dead, don't know yet) but that thing is really complex. I'm in the process of tracing the schematic but it takes ages to do so. There're CMOS switch, Nor gate, JFET switching, lots op amps (really complicated circuit for a tremolo).

I contacted Dunlop for a scheamtic and no answers (obviously).

thanks

Hi all,

I'm gonna try to modify it true-bypass, but I don't know how to get ALWAYS ON. :?

Anyone has the schematic?

I was repairing one and took some photos. A switch was trashed and had to be swapper out. You'll be able to tell which is the replacement.

Anyhow, it sounds amazing. This has to be the coolest flanger or phaser pedal I've ever fiddled with. Would be very cool to trace, but the two sided PCB is a bit beyond me. Got what I think are some decent pics though, so maybe this is within the reach of someone here.

Hi all,

First post from a long-time lurker - I hope it is of some use...

I recently got a 'Glove OD' (which I really like at the moment) but found it made an annoying clicking noise when the internal switch is set to 9V - there is a short (zipped) mp3 file of the noise attached. (This is independent of amps, cables, power supply, etc. but is with all the knobs fully clockwise to emphasise the noise for recording.) It becomes very noticeable if the OD is used before delay or reverb (but this...

Can anyone here tell me about these? I picked one up less than a year ago used at GC. It is made in USA unlike my other DOD FZ69 which blows it away! I wanted to find out if anyone knows how to do mods on these to get some of the feedback out, maybe make a a bit darker sounding and, clean up the circuit. This would be my first mod ever on a pedal. I would appreciate any input from a competent source. I tried looking up stuff on it on here and, it seems there is only info on the DOD FX55B. I...

Anyone ever had look at these? :scratch:

Here's what I have on the original vintage OD-880

Here is another one schematic for comparison and workbench if someone wants
to get 808-steroids sound. 8)

what is the main diference between the guitar big muff and the bass big muff?

so i need to switch between my dynamic mic destinations in a live situation, and was thinking that even though i'm a complete electronics novice an XLR a/b switch should be simple enough to put together?

after a bit of internet research there seems to be a lot of different methods some using 3PDT some 2PDT, some powered, some not... so im a bit confused as to what to go for...

This is pretty much all i need (minus the pad and trim):

Any help would be much appriciated :D

So this is my first venture into bring a commercial pedal back to life. Not super familiar with flanger circuits. As it stands right now, it won't pass a signal when the pedal is on or off. The LED does come on though. I see a bunch of solder bridges on the board but i'm not sure if someone tried to fix this before it landed in my hands. Where's a good place to start?

hi community,

i´m just repairing an boss rv-5 that was fried and found the culprit, it is a choke with 4 pins right after the power input, on the pcb it is marked L1 . when the choke is removed and bypassed with 2 wires, the effect works perfectly.
now i wonder what the value of this choke is.
does anybody have a schematic of the rv-5, or other boss digital effects for that matter (maybe they all have a similar power input scheme ?) or know what the value of this part could be ?

cheers,...

I have this old black finger:

Issue is I have no idea where power and group from battery is supposed to go to
As you can see, someone before me tried to fix it so now there's 2 battery clips (????)
Any help would be appreciated!

My 'brother in metal' Dean Cascione with the first two in a series of demos for the new 2013 limited edition DOD Overdrive Preamp 250 in the style of Neoclassic Shred - Finally how it was meant to be! ;)

Live Performance - Arpeggio Assault

Dean unintentionally misspoke and meant to say that it doesn't color your tone when it's off. It's all good!

I have this new 'metallic gold' DOD 250 (by DigiTech) too and it made me replace my favorite 'Neo-Classic 741 Overdrive' scratch-built clone...

Looks very much like a Little Angel to me, but I'll go over it in the next couple of days to confirm it. Funny that they thought sanding the ICs would stop people recognising a PT2399 (especially with the regulator under the 500K pot)

this is the same pedal korg SDD 3000?

Hi I'm new to the forum,

I picked this up from Ebay. Used Ts9 with Keeley mod plus and also the clay jones od mod with a 3 way selector switch. I've been using a cheap tube screamer (sound tank) to boost my guitar's signal to the amp (engl savage/Peavey 5150II). This pedal should be a nice replacement. Also looking forward to getting some warm creamy lead tones from it and experimenting. Anyway, thought I'd share.

Here's the ebay listing;

cheers, Brad.
