My PCB has two diodes in the layout as well.  A little 5817 never hurt anybody.

Thanks again.

I can’t find a build doc that is specific to the version 1 PCB.  The only build doc that I can locate doesn’t show an R11 on the schematic.  The version 1 has an R11 marked on the PCB.

Checking with my meter indicates that R11 connects pin 1 of the volume pot to g…Read more

With the 5457’s bass eq control is more effective.  Both tone controls seem to more responsive.

The pedal sounds more like Barry’s demo.  I’m calling this one solved.

Thanks for your help with this one Barry.

I can run the bass knob around 11 o’clock and get a good balance of tone.  I’ll try your recommendations at C16 and let you know.

I run my pickup height kinda low.  In comparison to my SG or strat, the neck pickup on the LP can…Read more

I noted in the build documents that you can increase the bass output by increasing the value of C1, C3, & C16.

I’m guessing that it would be possible to lessen the bass output by reducing the value of these 3 caps.  My Les P…Read more

So I put the boards together, (and like the NT 6…Read more

A 70’s boost into a Ludicrous Speed into a Black Dog.  Haven’t got it boxed yet, but hope to have it going soon!

These NT singles Barry has developed are awesome, and I’m looking forward to some awesome builds with them!

I can’t wait to see what you’ve come up with!

I’ve always been a fan of running my boost in front of my drive.  More volume and gain right when you need it!

I’m considering a homegrown version of your NT 70’s drive.  I’ve had a Black Dog and a Ludicrous Speed board around for a while now, so I thought I would put the NT 70’s B…Read more

I’ve been getting into octave up fuzzes and had a feeling the 60’s fuzz would do it well.

The build went smooth and easy with no hitches.  This thing sounds awesome with and without the octave up!

Congratulations Barry on the layout of all the NT boards.  You’re onto something r…Read more

I’ll be looking for a better tester.

Thanks again.

I use it to determine and verify specs on transistors, JFETS and other components.

I occasionally get readings that don’t make sense to me.

The above photo shows the readings for a J201.

This photo shows the readings for another JFET (not a J201).

I’m confused by the…Read more

I think the pot is wired right because it gets louder as it’s turned clockwise.

I had my voltage around 5 volts (whatever the build doc instructed).

But I’ll give another check this weekend.

Thanks for your help.

Comparing the schematic, I don’t see the resistor that is referenced in the Stage 3 build docs to adjust for attenuation.

Anybody got a suggestion or a hack?

Thanks.

Anyways, I’m working on a Muff’n Triangle version. I found I don’t have any 390k resistors (for R5, R10, R15, R19).  Do you think 430k’s would perform ok without causing a…Read more

I put my first combo in a 1590DD.  It had plenty of room.  One difference with this one will be an order switch to choose where the boost goes; before or after the drives, but that shouldn’t require any more room.

I’ll hopefully be getting started soon.  I’ll be posting pics when it’s done.

I’m excited to…Read more

I’m thinking of a Plexi-Plus and a Black Dog, with a Stage 3 to round things out.  Still working out the enclosure size too.

Thanks again.

Any kind of drive you might need with a tone tweq too!

I’ve been considering one of the Tube Screaming Preamps.

Thanks for sharing.

The case is 18.5″ wide and would hold about 7 pedal enclosures worth of effects.  I like the idea of having an “all in one ” solution for…Read more

Good stuff.

I was wondering if you could elaborate on how you used the 2KJ to perform “channel switching”.

I can’t see e…Read more

On the pcb I have. lugs 3 & 9 are tied together and I didn’t find a solder pad that was connected to them.

Sorry for the confusion.

Thanks.

I don’t think that’s going to work for me.  I need 7 & 9 for the second effects send and return.

Think I’m gonna have to skip the PCB.

Had a “Duhhh” moment when I first saw your response.

Do you think there would be a need to ground the “off” channel to prevent popping or noise?

Thanks again for your help.

I’ve built one using a board from another supplier that was an effects loop switcher.

It seems like I read somewhere on here that someone used a 2KJ to accomplish the same thing.

If not a 2KJ perhaps something else.  I could probably wire up a 4PDT (I want status LEDs) without a PCB, but a…Read more

These drive circuits are freaking awesome!  Anyone considering one of these should do it quick!  You ne…Read more

Bruce R. please don’t think I was being critical of the boards layout or design.  While I only have a limited knowledge of things electronic, I appreciate the challenges of laying these PCB’s out and think you do a great job.

As I said, I really prefer board mounted pots a…Read more

My problem is I have trouble getting my iron on the pot legs without melting a cap or two next to them.

Does anyone else have this trouble?  What do you do to avoid it?  Sometimes it’s so tight I feel like I’m playing the old “Operation” game.

Thanks.

I just installed a 150k at R5 and there is definitely ga difference in switch positions now!

I might should have gone with 220k but figured I’d split the difference.

Thanks for your help Barry, this really is a great sounding circuit.

I don’t have a rheostat on hand.  (I do have some trim pots though)

Do you have a feel for what resistor value would be close to your setting?  I can’t really determine the position of Oscar’s rheostat, as well as not being able to determine the approximate resistance…Read more

It sounds good though.  The gain control doesn’t seem to be problematic so I’ll probably leave it.

The pedal sounds good.  There just doesn’t seem to be much difference in the switch positions.  Don’t really hear the “hot” setting.  I saw something on the forum about someone else…Read more

To avoid the troubles I was wondering if an A500 might work.  I understand the sweep will be different, but will it change the tone of the circuit?

It will be the gain control.

Thanks Billy.

I missed one…  I have everything I need except 1k8 resistors.

I have 1k5 and 2k2.

Would one of these values work?

Will there be an adverse effect on the circuit?

Thanks for your help.

I appreciate the work you put into these circuits.  I’ll be checking the grounding and reflowing the joints.

Right now, I’m running the transistors spec’d in the build documents.  I think I’ll experiment with some other transistors.

Thanks again for the info.

Oner of the pads on R3 (the end towards the center of the board) had separated from the trace on the board.  The circuit was open after that point on the board.  You can see the bare copper in the photo I posted above.  Just couldn’t see the forest for all of the trees.

I found it using a sound source (little mp3 player) an…Read more

Thanks.

I’ll check R2 & R4.

Thanks for your help.

I connect my guitar to the input on the board and I connect my amp input to the output on the board.  I have a temp DC connection to power it.  I should get the effected signal from the board.

I don’t usually install a board in an enclosure until I hear it work.  The footswitch is on a pcb of its own, so it’s pretty st…Read more

i’m sorry i forgot to mention that i had the connection colors reversed on the input on the board.  A mistake I left uncorrected to prevent one more soldering/unsoldering on the board.

I am connecting it accordingly when testing.

Thanks,

The build went together smoothly.  I had to improvise a trimmer connection since the only one I had was a little large for the board.

I have no sound from the board.  I have checked component values and replaced R3 which was a 510k rather than the 470k ca…Read more
