How do you wire a Tone Tweq to a NostalgiTone 60s Bluesbreaker

[Chris Huss]

I’m not a pro at stomp pedals and would appreciate help wiring a Tone Tweq to an NT Bluesbreaker.  I get wiring the EQ PCB into the signal path, but how do I eliminate the TONE pot on the Bluesbreaker PCB.  Could I just replace pot with a trimmer set to middle of its travel?  What value trimmer should I use? OR would I wire in a fixed resistor? and of what value?  OR jumper the pins?

Thanks to all the gurus out there.

Do you want to have a volume control on both boards or maybe eliminate the tone and volume, and let the Tone TwEQ do both?

You could wire the in and out of the TT to the pads for lugs 3 and 2 of the tone pot to keep the volume pot.

You could wire the in and out of the TT to the pad for lug 3 of the tone pot and to the pad for lug 2 of the volume pot. So essentially stick it between the input of the eliminated tone and the output of the eliminated volume.

There are several other ways depending on what you want, including  leaving a 25K trimmer in place of the tone, set to half way, and lift R11’s leg from the pad going to C10 and wire in the TT between the R11 leg and the open pad. But why bother? Cheers

Thanks for the quick response. Wow.  Here’s what I had in mind.  I want to build a Bluesbreaker with EQ; so, pots for VOL, GAIN, BASS, MID, & HIGH.  I’d also like to add a DPDT Wiring Board for selectable diode clipping. If I pull it off, I think I’ll have something close to an Analogman King of Tone.

I know it’s a lot to ask, but thanks for helping.

Easy and fun to add a DPDT board. Don’t populate D1-D4. Populate the DPDT board with your diodes instead. Use sockets for more versatility. For jump off and on points from the main board, think of them as A and B pads, use the left hand pad of D1 and right hand pad of D2 and wire them to the main 2 pads of the DPDT board. Those connections should trace to the center lugs of both sides of the DPDT switch. You can use a on/on type to select one end or the other of the mod board. Another choice could be to use a on/off/on type switch which will offer any available op amp clipping without diodes from the TL072. So three clipping choices. The roto-tone board offers even more.

You rock. I just ordered my pcb so I can work on this.  Thanks for the help. I’ll try to post a pic when I get it built. Thanks again for the help.
