So a good friend just asked me to add relay silent switching to his Micro POG as the click is way to loud for him.

I was gonna use sabrotone's layout ( but the Micro POG has some ribbon wiring going on inside and I'm not sure which is input/output/ground/led/etc.

Could anyone help me out with identifying the 8 wires coming off the board? I would GREATLY appreciate it! I can upload pics if they are needed.

Thank a million in advance!

I'm currently playing two separate amp heads into the same mono cabinet (not at the same time). I'm getting tired of having to unplug the speaker wire from the back of the amp every time I want to play the other one.

Can a passive junction box like this be built? If so, could someone draw me a schematic? It would be greatly appreciated.

Again, I know you can't play the amps at the same time. And I don't need any LEDs or a switch. Just two jacks in and one jack out.

Hi friends,
I would like to get some 1290NS enclosures. I like curves :oops:

Also, I have 3 unused Hammond 1590BB that I want to get rid of.
2 are in their original packing, and 1 with sealed removed and with drill measurement marks (planned to use it, but decided not to).
I don't mind trading with Hammond 1590B, but I'd prefer to get my hands on 1290NS.

Here's a layout I did for the tremulus lune. I wanted to fit it on a 15x15 radioshack style perfboard. Layout is verified. Enjoy :D

I recently acquired this wah pedal and couldn't find any info on it.
It is in a metal case similar to a colorsound wah and the circuit also looks very similar to the colorsound inductorless wah.
Here are some photos:

Just for the record; close to a distortion + from MXR with some tweaks.

I also had a Distortion 10 from this maker a LONG time ago; those had germanium diodes

I built a Swamp Thang tremolo per this layout and the linked schematic.

When I use it it seems to boost my signal as well and add tremolo. The tremolo seems to be either drastic or extremely subtle with not really any points in between. I can't say that with 100% percent certainty as even direct into my laptop with no volume my guitar was bothering my sleeping roommate (sigh). I can do a proper audio evaluation tomorrow.

I do know something is wrong though, as the LED behaves strangely....

A friend who runs a rehearsal studio just dropped off a couple of DS1 and a HM2. The newer DS1 is healthy but the 2 old pedals which needs ACA adaptors are acting up. I'm pretty sure these 2 were used with a variety of AC adaptors which i suspect is causing the problem. Also they are quite old and never had been looked into since they were bought 10-15 years ago. i get to keep the bad ones and need help fixing them.

DS1 works with battery and with regular adaptor daisy chained with other...

Hey there! I recently built a Colorsound Overdriver following the layout.

1. My problem is that the drive pot only really does anything at the very end of the taper, the sound is non-existant when the drive is low or down, clean in the middle and then all of a sudden is fuzzy. There's no overdrive in the middle, and the volume is very low until the very last portion of the taper. The pot is a 10k linear pot as suggested by the guy on tagboardeffects. I've heard that Colorsound Overdrivers are...

I have a vintage EHX Clone Theory that needs a new SAD1024 BBD. Any of you chums have any lying around here? If so, let me know because the Peter Hook in me is trying to get out, and he NEEDS this pedal to work.

Thanks!

Hey Looking for 2n1306's Have plenty of parts to trade or will buy.. Please get to me.. Have gold 2n404a's 2n167a for trade

Got this at a good price during sale. I read its based on the Champ? using it at home for practice, nice basic sound from 1 Vol and 1 Tone. The TS circuit is a bonus but i rarely used it since i i'm running pedals. it stopped working a few days ago and at the dealer right now to get it fixed.

i didn't bother to open it up to see what's inside - pcb or smd or whatever. anyone has done any work on this amp? any good upgrades/mod? standby switch add on? anything? i'm keeping this amp since it's...

Hello!
today i tried one Zvex box of rock -boost section- based booster with my friends active pickup guitar.He uses his amp's distortion and he needs a booster for a solo section .We used the effects loop for the booster .The problem is that we have a feedback problem even if we go to 2 meters away from the amp.I think to put a resistor from the input jack to the ground or to put in series a resistor to the input jack to reduce the power of the pickups.
Also until now i can't measure(and...

Hello,

I'm on my 3rd build and after 2 really great pedal builds, this one is killing me. I'm making a volume booster (Keeley Katana clone) and have all kinds of problems. While debugging I noticed the 3pdt switch had a very small amount of resistance on the ground lug. Does this mean the switch is faulty? My overall problem with the build is an actual volume decrease when engaged.

Thanks so much for your time and help.

ok, i built another fuzz, tried bc109's but they are just way too hot. bc108's tho, offer a pleasing tone, as do ac176 ge's. tested it with low gain transistors, you can get useable tone with anywhere from 30-120 hfe. i like the classic fuzzface-ish ratio, 87hfe q1 and 105hfe q2. this is verified, built it tonite, it has the potential to be TOO distorted. it's pretty sick, you can overload q2 if you want and make it fade in and out. not that you'd wanna do that. overdrive your amp, add fuzz, or...

does anybody know something about these amps?. schem? or things like: is the ts surface or through hole?. tube voltages?, etc. it looks from the block diagram that the 15 is similar to a fender, gs, ts, gs. but there's something intriguing about the 30, judging from the block diagram i suspect something similar to a bassman, but the gain pot is in an odd spot...any opinions?

Got a cheap Belcat Distortion pedal.
I know the Church of Distortion is a very Broad one and this pedal is on the crunchy brittle treble end. So after finishing my Germanium FuzzFace the Belcat was just to Crackly for me.
It has to Red Diodes handling the clipping so first I tried to OA90 Germanium diodes and that was just to smoothy with huge drop in volume. Maybe 4 or 6 might sound better but I only had two at hand. Then I tried 2x1n4148 very ordinary with a little more volume. 3x1n4148 sound...

Sound Sample:

I only sell the one in black metallic color about $100 exclude shipping.

can anyone explain to me how this is done? the best i can figure is that i can use a 4pdt and millenium bypass 2 plus to have an led. is this the best way to do this or is there some other way? If this is the best route can someone please draw a wiring diagram example or try to explain it to me. i would like to be able to still ground the effect input but i am at a loss to how that portion of the circuit works. i have read all the articles on it that i can find and i understand how the led is...

hey guys, i think it was scruffie asked if i could up some shots of this beast.
i'm trying to get it to work again for a friend. have replaced ALL the electros. one was a 22u that had had the covering removed. seemed to me the side referenced to ground was obvious, and it was the only unmarked cap on the board. i used the schematic from toppopicione's but i believe that may have a couple errors.
or it could be my eyes...that schem is hard to see.
unfortunately, i don't have a digital camera...

I have a sick SLO on my board :(

When I feed it with a loud clean boosted signal it cuts of in a weird way.

Here's a clip I recorded:
1. Dry signal
2. SLO only
3. Voodoo labs sparkle drive used as a clean boost into a SLO
4. Sparkle drive only

Any ideas what could cause this behavior?

Hi there, i am planing to rehouse my tremolo in a morley wah pedal, and use the LED/ LDR rocker pedal to vary the speed of the tremolo. Is that possible? I can't find any schematics on this one. My idea was to use the LED/LDR instead of the speed pot. Hope you can help on this one.

Hello everyone.

I made a vero layout for the 5x midi thru box diy project released by highl liquid

This is not really a pedal but it will sit in a hammond box ( :mrgreen: ) and will be used in my guitarrack so I guess it qualifies.

This is the first time I made a vero layout ( I usually go with pcbs but I wanted to try vero) and I hope someone will step down and take a look at it to varify it.

I hope this is the right forum for this kind of stuff, if not just move it :)

Kinda new hi guys, Anyone know anything about this pedal? :scratch:

Hi guys,

The recording studio I am based at has some NOS valves for sale on ebay. It includes some ECC82s and EF86. It might be worth your while taking a look. You can see them at

Cheers,
