Re: Mod for Boss DD-3 always on

Just to update -

All done. Remove Q010 and bridge across, removing the Diode pin. LED isn't "On" but that matters not for my intended use.

Mod for Boss DD-3 always on

Hi all, Have had some great success in the process of integrating my DD-2/3 (undecided) into my MultiFX board. Last thing to get my head around is wiring it so it is always on. It doesn't use the standard flip-flop bypass in most Boss pedals, so bridging is out of the equation. It know it's possible...

Re: Bypassing Rotary Switch on Boss DD-2

With that in mind, would I be correct in thinking that I could wire a DPDT switch to toggle between Medium and Long, on the basis it's a 2P4T switch to start, and "post integration", I only want to use 2 of the 4 functions. Absolutely, that would be quite chill. You can go even lower! If ...

Re: Bypassing Rotary Switch on Boss DD-2

Hi! Unfortunately, this is a little bit more involved than just rewiring the circuit a little. The switch exists for a good reason; let's look into why it's there in the first place. This pedal works quite differently than modern digital delays, and is actually closer to a classic BBD delay, with a...

Bypassing Rotary Switch on Boss DD-2

Hi all, How might it be possible to bypass the S/M/L switch on the DD-2 so that the Delay Time controls the entire sweep from short to long? DD-2 schematic for reference: http://www.8bitsindgenug.net/boss_dd2.png I'm looking to integrate the DD-2 into a multi-FX board and think this would be a nice ...

Re: Baja B K Butler Tube Driver [documentation]

So could anyone post some info for me (vero/schematic) to convert the Tube Driver from AC to DC? I've successfully removed the transformer and have adjusted a few components to bring the modern one closer to the 80s Chandler one too. The final piece of the puzzle is getting rid of the hum. Any help ...

3 Way Buffered Amp Splitter

Hi folks, wondering if you could help me...

Is there a circuit layout floating around of a 3 way amp splitter - with a buffer? I've done some searching but found nothing!

Cheers!

Re: Wiring a pedal without a 3PDT switch

You would still need a stereo jack for the input so the battery would turn itself off when the pedal is unplugged. Mono is fine for the output. The input jack's tip needs to be connected to the input of the effect. The output jack's tip needs to be connected to the output of the effect. The LED cir...

Wiring a pedal without a 3PDT switch

Hiya folks,

Just wondering how you hardware a pedal to be "on" when you put the plug in and off when you remove it? I believe you use mono/stereo jacks for the output/input etc but how would one go about wiring that up?

Thanks

Phil

Re: Making up 50k resistor using 2x100k in parrallel

Put the 1st 100K resistor right where the 50k resistor is supposed to be. THen solder the legs of the 2cnd 100k resistor to the legs of first resistor. Piggy backing them works just fine and is not that difficult to do. No need for a pic to explain this one I think. Either that or use a 47K resisto...

Making up 50k resistor using 2x100k in parrallel

Hiya folks, wondering if you could help me...I'd like to make this circuit - typical bootstrap buffer, however it requires 1x 50k resistor. These are hard to get hold of, if not impossible, so I'd want to use 2x100k in parrallel to bring it to 50k. Question is, where could I put them? Is it just a c...
