Re: DMB Lexi pedal, gated fuzz!?!?!

Thanks, let's see if someone will help in the tracing job. I'll do my best but for the next days I'm with my phone only, and I'll be travelling. be patient

Re: DMB Lexi pedal, gated fuzz!?!?!

i'm happy you have the sound back! it's strange anyway that this pedal is so current-hungry. There can be exceptions, but usually analog pedals don't need many milli-amperes, and this circuit seems to be quite simple. ....maybe something else is happening? with some other pics of the top, & bottom s...

Re: Xotic - AC Booster [ goop-alarm ] [traced]

while you're modeling, if you want, please try with and without D5 in aionios configuration; i'm curious about the differences

trimmers can be very touchy, even a micro-adjustment could be significant

Re: Bazz Fuzz - No sound

also, be sure to connect your guitar to the INPUT jack and not the OUTPUT jack (happened many times to me...)

Re: Keeley Darkside

hi and welcome to the forum! ...i don't want to be pessimist, but tracing this pedal with only some pics (even if nice detailed pics), would be very hard; i don't say impossible, but hard. it would be difficult with the pedal in our hands as well. some desoldering could be needed (potentiometers, ja...

Re: Stereo overdrive

hello, if i understand correctly, you're just asking for 2 indipendent OD pedals in one box. well, of course it's feasible, and you could also try using 2 different, already available, OD pedals ... the only little complication that i see (if you haven't got a pedalboard switcher) is to activate\dea...

yes, that resistor is missing on the layout.

Re: Xotic BBpreamo bass no Gain

No, probably not the pot here.
maybe a solder bridge somewhere around the clipping diodes, or pin 1 and 2 of the ic. In the feedback path anyway

Re: Xotic BBpreamo bass no Gain

Mmm, nothing changes if you turn the gain pot?

Did you check the wires connecting the switch? They are very flimsy. The first thing I do, when I mod mines is to replace them with some decent wire.

Re: Xotic BBpreamo bass no Gain

Perhaps the potentiometer itself is bad. Sometimes one or more pins loose the mechanical connection with the internal carbon trace, creating an intermittent contact.
This could explain the fluctuating voltage.

Edit
You should have noticed that also the volume of the pedal fluctuates though...

Re: KMD Distortion 70's [schematic]

i'm very sorry, there was another error: DISTORTION POTENTIOMETER WAS WARKING BACKWORDS.
i fixed the two layouts, and now i'm 100% sure they are ok.
you can find below the last revisions of the "vintage" and "modern" version

Re: KMD Distortion 70's [schematic]

...i'm just having fun with this layout - here is a "modern" version of the circuit, with some filtering on the 9V(so that it can be used with a power supply without issues), and a pull-down resistor at the input to avoid "pop"s if wired in truebypass; i've not put the diode for reverse polarity pro...

Re: Nux looper core pedal malfunctioning

the best thing you can do is to accurately inpect the PCBs, looking for something wrong - a disconnected cable, a broken solder joint, a burnt component... - you had better use a magnifier, a good one. start checking very well the solder joints on the ribbon cable and on the relay (since jacks and p...
