Global Annoucements / Re: 2017 Year-end Wrap-Up

i haven't been active in a few years, been building amps mostly though i do enjoy the monthly visit to the forum and all its great members.

a DIY site had a donate button a few years and he managed to recruit a lot of money, I think you should do to the same, mainly because the service you provide is heartfelt one, your projects, other than being perfect, have a certain positive energy to them, i always feel pride stomping on a pedal with a MBP pcb.

i've had 5 hard financial years, but if you put up a donate button, i'm gonna donate, not as a donation, but as an acknowledgment of your great site

General Questions / Wooden effect enclosures
« on: June 20, 2016, 02:06:54 PM »
I recently came across a guy who does amazing woodwork for anything guitar, he also does pedal enclosures made out of wood.

I suggested he needs to sell those as the pedal market don't really have such options, I will post some examples here:

what do you guys think is a reasonable price ?

is 45$ shipped worldwide an ok price ?

will any of you be interested in such an option ?

checked the entire circuit with a good brand new multimeter today.

coulden't find anything.

until i checked the grounds and found out i had one ground on the switch loose, it had an intermittent connection, soldered it up well now and is all good. voltages are as expected.

serves me right for being dumb and lazy and not wrapping the wires around the switch lugs.

thanks for all your help guys, i think i would have given up on this if it weren't for you.

You are corret.

I just came to post that i stupidly mis-counted the pins (i SWORE it woulden't happen to me, huge embarrasment)

the correct voltages in the correct pinout is

pins 1-8:


I'm using a power supply, not a depleted battery, could the 47uf cap or 1n5817 be defective and not rectifying correctly ?

cause i do get 9v at the source.

i'm guessing the 1n5817 is for polarity protection only ?

but the package i got it in says 100n

I'd have to measure them to be sure

Took some readings with the multimeter

from pins 1-8:


that don't seem right ?

checked R6 and R7 values, they seem  fine at 390k and 470k, c9 is a filtering capcitor ? tayda has a weird way of writing values on the capacitors, so either this is 100n or 220n, would it matter if the value is 220n?

it's orange, they are 470k.

I will post voltages on Saturday night.

I don't think there's power coming to the chip though, i tapped on the lugs and i get no disturbance in the sound. my Multimeter decided to died on me today :(

thanks for the advice.

I tried it with the OPA (jumpering R12).

I took it out and put a TL072 and put R12 back in and i still get a really loud hum noise.

I put some pics in case you guys spot anything, I tried everything i could think of but i get no sound :(

Hey all,

I've just finished a cupcake build, no parts repalcements except i'm using OPA2604 as an IC.
I also didn't hook up the LED on the board, I've used the standard diagram with positive going into 9V and negative to the 3pDT.

when i turned it on it didn't work and made a very nasty sound, then after a few seconds R12 started to smoke and is now completey burnt.

checked all connections, pinouts etc and all seemed fine, any idea why R12 would smoke ? could the led not being connected on board (I left the LED connections disconnected) cause this and the circuit not to work ?

i just finished sorting like 200 Vitro ohm 1w Carbon comps.

love the sound of carbon comps on my JTM45 clone and other high gain build.

any chance you could share the schematic?

Will put pic up later, a unit i built to be sold on ebay.

enjoy :)
