Don't post in this forum asking is there is a schematic or layout or info on XXX pedal.
There is a subforum setup for requests already. It is located here:
REQUESTS FORUM
Any requests posted here will be moved to proper sub forum, and I'll also make nasty remarks about your mother. :mrgreen:
also, if you have a problem with your build, post it in the WORKBENCH. these threads are for circuit analysis only. by all means, if you discover something we should...
Hello, everyone!
I was lurking the forums for quite a long time. During this time, I nicked plenty of circuits and ideas for my personal collection. Now, the time has come for me to repay in some way... even if it is a small one :)
Three years ago, before I have started dabbling in the FX scene myself, I have acquired a Hiwatt Tube Overdriver pedal. It was being sold brand new at a half price (they must have not been popular here in Poland), so I picked it up, while my friend bought a Hiwatt...
Hardly what i'd call a Modern Stompbox but the Schematic dates it as 3 years out on '75.
Anyway, here's a Redraw of the Factory Schematic for those of you with poorer eyesight. I think the Redraw is Correct I can't recall where I got the original Factory one from and nor can I confirm its Authenticity so if someone knows the link to that or if it's correct, that'd be handy.
I might see about converting it to 9V & V3205s as it's quite a nice simple looking Delay Project.
I'm half tempted to get a Liverpool just to see what's inside, but if someone has already had a look, I'd be interested to hear it.
Supposedly, some guy on YouTube bypassed the speaker sim so he could use it with his amp - that's what I'm looking for.
I have a PDS 20/20 that is driving me crazy. The delay effect timing is right, but the effect on the note itself flanges up and down like a wave. It's like rocking a pitch shifter back and forth. I have replaced the bad caps, checked all the transistors, and swapped around several of the ICs with no change. The voltage regulator is also tested fine. I have no idea where to look next.
Last night I sold my MXR badass 78 distortion, so this morning put the money towards an AMT S1 legend series Soldano pedal/preamp ordered from Thomann (i'm sitting by the letter box waiting). I really want to have a look inside and work out what makes this pedal tick. If there is any info available already it would be good is someone can point me in the right direction please.
I know the designer behind it has had quite a bit to do and say on these and other forums. From the clips at the AMD...
I don't know if there is much interest for this as it is not really a pedal but I find the circuit interesting. Also if I posted this in the wrong section please move it to where it should belong.
I've always liked the Boston guitar sound although I find these headphone amps to be a little weak in accurately producing that sound. I haven't had the chance to play one of the original headphone amps but I have read that these sound nothing like them, minus the reverb and chorus. I mainly use...
Anybody have a schematic for the MXR Omni M180 rack? I'm looking to get pot values for replacements. I'm also hoping to find the schematic for the footswitch to rebuild that. Thanks.
The pedal works perfectly in 8 second mode. However, when I switch to 2 or 1/2, the effect doesn't work. When it kicks in, it basically doubles the signal overtop of the input, i.e. Just makes the sound a little warmer. There are no trails, echos, or repeats. The delay controls don't seem to change anything. The controls all work perfectly in 8 second mode however. I've recapped and swapped ICs. I get the voltages on the 4066 when sliding the selector switch. Interestingly, if I jump pins 3&4...
Does anyone know what Pro Co has done to the RAT to make it a FATRAT? I'm talking actual circuit and/or component changes not sound/features. If anyone has any gut shots or an actual verified/traced schematic that would be great. I'd like to update my comparative multi RAT schematic (below) to include this new RAT variation so I'm really curious as to what they've done.
I'm interested in modding my LMB-3 with the Steve McKinley Thunder mod. Wondered if anyone has tried it and knows what it actually is.
I can't afford to send my pedal half way around the world to get this mod done so want to do it myself, but I can't find any information on what the actual changes are.
I had this done a while back. This was the mod that was intended to make the Deluxe model sound more like the original Electric Mistress. This was done to my 1990s V4 electric mistress. He removed C3 and C20, and put a .0033uF cap between the points connected with the red line (see attached image). As far as I can tell those were the only changes.
What was the effect? The sweep sounded a bit more airy and whooshy. Kind of neat, if you care.
The schematic for the V5 version (with the wall...
A lot of people really like the old Rockman modules. They have been out of production for a long time now yet there are no schematics available. I understand the US patents expire after 20 years so they would not now be covered (?). Looking at pictures of the stereo chorus pcbs, it looks like it would be possible to clone it and I would love to have a go but without an accurate schematic it would be a world of pain. Has anybody else tried this?
Does anybody have the schematics of the EBS Multidrive perhaps or else some information about the signal switching?
I'm actually not so much interested in the internals workings of the drive but more the switching arrangement and input/output stages because it pops when enabling it.
The foot-switch seems not to be true bypass but a simple one pole switch. This probably implies that the switching is done electronically and that the foot-switch provides a logical 1 or 0 to the electronic...
Recently i've give a try to some demonfx pedals, since i have not much time to build myself.
The last was demonfx full bb preamp, clone of the two custom shop xotic bb preamp, mid boost and comp versions.
The first thing i noticed when i opened the lid, is that it's based on the single volume pot schematic. That seems not to be correct, as Aionfx tracing journal point out.
The pedal is as usual a copy of the classic ts with a useful active tone section. Is has both the two options sold...
Hey lovers of the deep tone,
attached you can find my attempt to trace this big tank.
It's my second attempt to trace a pedal so please be kind. I used a continuity tester and the magnifying glass app with the flashlight of my cell phone to get it done. The schematic is made with Kicad.
Unfortunately I don't have a lot of knowledge in electronics. I don't now exactly which component is part of a feedback loop and which is a high pass etc or (and) especially for this pedal which component is...
