Dunwich Amplification General Discussion

It’s not that complicated, but I used a bunch of words :)
The bottom line is that you want to modify the clean signal with a filter (extreme EQ) to make it sound best when blended with the distortion. However, that EQ modification changes the signal that hits the distortion circuit, so the character of the distortion changes vs. just sending a raw clean signal to it. I didn’t like the results I got with the blend/loop pedal I tried (the IE Divaracator).

It’d be easier to design a blend as part of the pedal. I was trying to think up a custom blender pedal, so I could insert any pedal I wanted in the blender’s loop. I found it wasn’t as easy as I had hoped for an amateur :)
which is why I love my Broughton Ghost Trap. Two loops, each with variable High and Low pass filters. The High send is influenced by a HPF and then the High Return is influenced by a LPF (to help clean up fizz and hiss), and then it's vice versa for the Low loop. Low send is influenced by a variable LPF and the return is influenced by a HPF (to remove boom or too much low end). Then it's all blended back together and Bob's your uncle.

I never had success with blending two full frequency signals together or having a High and Low blender that uses the same crossover frequency like the Divaricator. The Ghost Trap solves all that and more

I'm not going to try to second guess Nick's work on the blend.
For the record, the best blend I've ever encountered on a fuzz pedal is the TAFM. The best outboard blend is the custom blend I had Broughton make for me. One vol for the FX, one for clean, and a tone mesh the signals together instead of layering them. It's a cleaner version of the LS-2 design. Now I don't have to care about my drive pedals having a blend or having a junk design like the Boss ODB-3.

Are there specs for this online, or is it custom?

Custom. We built some cool tricks into it also. When loops are on but nothing's in the loop it still works, so it's an incredibly powerful tone shaping tool. Dual outputs for either mono (mixed) send or the potential to send each loop to a different amp. You could also send different signals to different amps using just the Send of each loop.

The way I was mapping it out, there was complexity with how the pass filtered clean sound hit the dirt circuit. There is a gain reduction which is a natural occurrence with the pass filtering (cutting signal cuts the signal, surprisingly ;)). The dirt circuit responds and behaves differently than it does with a full gain clean signal. I had an IE Divaricator for a while, hoping it would shortcut what I wanted to design, but I quickly learned that pass filtering and/or crossover prior to the clipping starts creating new issues to consider. It certainly gets tricky.

The other issue with pass filtering is the fact that it is static, so if you set the filter frequency, you may get clean tones blended in on low notes, but get no blended clean tone on higher notes, if the fundamental is above the filter frequency.
Just send the clean blend signal through something like a bass's tone knob rolled all the way back.

Just purchased a VT off a fellow TB'er, I must say I am giddy with excitment as I have watched the "Demo Vids" video of this pedal like 500 times. Been a bucket list pedal for me for a while now. I look forward to it joining my dirt section of my board with the MBD-1, Prunes and Custard and Green Russian.
It's a good one!

It’s wonderful. Dunwich knows dirt.
 
Wizard Fuzz 125B boards are getting moved along, through resistors (see instagram)
The rest of the parts are ordered today.
Trying to drill this weekend. We shall see.

Not a metric-shagton else too discuss. The Super VT is in prototype, still progressing to an enclosure ect.

No other bass-centric projects I can think of off the top of my head.
 
Did you get a Night Owl Oscar? I think I saw an IG post with one paired up with a DA120. What do you think if it?

I designed that PCB from his schematic so I got one as a form of payment.

Its a solid always on tube boost. Runs at 18V. I didnt post vids but I can try at some point.

It must've been the Night Owl IG post that I saw.

I almost grabbed one when they offered $25 off, but I had a W&C Phat Phuk B on the way, and I figured two boosts would be silly.
...not that silly has stopped me :)
