Re: Menatone - Red Snapper (schem inside)

Check out the transistor in the lower left connected to the diode. What's up with that? IMG_9159.jpg Haven't seen any 3 knob DIY layouts with it. This pic is of a friend's 2003 RS. (Also found a pic of one from '99 on Reverb. Same circuit.) It sounds different from my clone - a bit more compressed, ...

DC cuts power to pedal (Doublebeat Fuzz)

Hi!

Would someone mind taking a look at this wiring diagram? When I plug into the DC jack, all sound and power is cut to the pedal.

(I've been clogging up the Doublebeat Fuzz build thread w this issue and it occurred to me that I should ask here instead.)

Many thanks!

Re: Roland - AD-50 ( Double Beat ) [schematic]

I think I'm close. I swapped out the rotary switch for a SP3T. That's working now. But the LED only works when a battery is plugged in regardless of whether i'm using DC power or not. Would someone mind taking a quick look at my wiring diagram and tell me what I'm doing wrong? I keep hitting the wal...

Re: Roland - AD-50 ( Double Beat ) [schematic]

Resurrecting this thread after having given up for nearly two years. Today I decided to take another stab. Turns out my issue is coming from the rotary switch. I really can't understand why. Attached is a picture of what I'm doing with it (mounted to another vero board to deal with space limitations...

Re: Roland - AD-50 ( Double Beat ) [schematic]

Is it just a short on the switching dc jack through swapping ground a battery +ve? I've heard that can happen :wink: haha. yeah, i think so. looks like i connected battery neg to DC tip instead of DC sleeve. still no go on the pedal though! not even an LED light... tested the battery and it's good....

Re: Roland - AD-50 ( Double Beat ) [schematic]

still plugging on this... no sound yet.

i just noticed that the vero layout says the pinout is CBE! is that right? which transistors is this layout using? i thought they were SC1000s which AFAIU are ECB.

thanks!

Re: Roland - AD-50 ( Double Beat ) [schematic]

Happy new year! Yes, diagram is ok now, but I would disconnect the two ring lugs on the jacks (but leave the input ring connected to power negative): This way, you only need to unplug the input to cut the battery power. Thanks. I've been trying all day to understand this but can't figure it out! Do...

Re: Roland - AD-50 ( Double Beat ) [schematic]

Your diagram is pretty close. The labels on the vero sow some seeds of confusion. The three "outs" on the right of the board are the three different tone outputs from the fuzz - they should be wired to the three throws of an SP3T, and the common connected to lug three of the 50k output po...

Bumping this in hopes that anyone who's made this from the vero layout will take a quick gander at my wiring diagram. Huge thanks and happy new year!
