I received the 2N5457’s I ordered and replaced the J201’s I installed initially.  This was my problem.

With the 5457’s the bass eq control is more effective.  Both tone controls seem to more responsive.  (I reinstalled the original cap values @ C1, C3, & C16)

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

Thanks for your help with this one Barry.

I understand that statements like “too much” are subjective and that that condition can be different for different people.  I can hear that this circuit has an open uncompressed sound and feel like if I can get the EQ better balanced it’s going to be a great circuit for me.  BTW, I’m running both pickups while testing, occasionally checking the bridge and neck.  Both pickups together is kind of my reference when I test drive stuff.  By the way, I finished a Black Dog board last weekend and it is fantastic with my LP in the middle position.

Ok, I spent a little while testing different cap values @ C1, C3, &C16.

First, I placed 47nF at all 3 locations.  This lessened the bass level and improved the clarity.  It still needed the bass control set very low if not off.  It did have more highs present.

Second, I replaced C16 with a 22nF.  This was a barely discernable improvement, still requiring the bass knob nearly off and the treble maxed to come close.

Third, it was 22nF & C1 & C3 with 15nF & C16.  Not much difference at all.

Fourth, 15nF & all 3 locations.  Better, getting closer to what I’d like, but still almost no bass control with treble at 3 o’clock.

I’ve checked my component values and don’t see any problems ( and I paid special attention to my “47’s”).

I’d be interested to hear from other people who have built this circuit and what their experience with it’s bass response was.

I’ll check my components again and verify.

Thanks.

Thanks for the help Barry.  I socketed the C1, C3, &C16 locations and went with 47nFs at the 3 locations.  MUCH better!

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 get dark, but it’s one of the things I love about it.  The stock BurstBuckers are awesome to me.

Again, thanks for advice on the cap values.

Thanks Steve, I finished the Ludicrous Speed and the 70’s Boost for my latest project today.

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!

[e_man]

That looks great!

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 Boost in front of both of them. I LOVE that LudicrouSpeed circuit.

Anyways, keep up the good work!!  And thanks for all of your hard work.

Later…

Thanks for the info gentlemen.

I’ll be looking for a better tester.

Thanks again.

Thanks Barry, I’ll check my resistor values.

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.

Thanks for the information Billy, I really appreciate it.

Printing everything out is a good idea.

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 hear the results!

Thanks for the info Chris.  The 2KJ is going to make this easy to pull off.

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.

Very cool Playsforfun!

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.

Very inspirational!

I have mine on my bench for quick reference. Along with the resistor reference and the wiring diagrams.

Good stuff.

I have been inspired by your combo build!  I’ve built a combo using a BEOD and a Tight Box with a Sho’Nuff Booster.  I used a loop switching PCB from another company to achieve the “channel” switching between the BEOD & the Tight Box.

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

I can’t see enough detail in your gut shots to determine how it was wired.

Thanks for any help you can give.

Forgive me wilkie1, I shouldn’t have typed lugs 7 & 9, should have typed 3 & 9.

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.

[e_man]

the 3PDT GPCB board I have has lugs 7 & 9 tied together with no solder pad tied to them.

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.

[e_man]

Thanks wilkie1!

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.
