Dunwich Amplification General Discussion

Active Mids - 20dB cut or boost and Blend

It is not the same mid control on the VT125Bs, it does not color the sound at noon.

Also just a big improvement in build simplicity.

Preorders? Maybe.

Imma preorder the **** out of that.

This is a fun combo. I like the sound with the ODB bass cut (switch up) and the clean BLoop blending the lows back in.

FYI - I put my custom Bass Driver up for sale in the classifieds, I love the pedal but that project has ended and I can't afford to keep it around now.

Hey Nick @dunwichamps , can you answer this for the group re: Bass Driver.

Is the tone knob just a standard passive treble cut? I'm a little puzzled by both the tone and treble knobs together.

 

[Beheroth]

if it's like the tube screamer it's based on, it's an active tone control around 3 khz iirc

 

[Matt Dean]

I’d love to try the Bass Driver sometime. I’m definitely loving my new Volt Thrower.

 

[Grahams Groove]

Dunwich is one of the few that always tempts me when Nick reworks/releases pedals. I want to try the new VT, Bass Overdrive, and a smaller form DA120. Him and Jeff from Damnation just make insanely good dirt for bass.

I have Bass Overdriver #2. It is a great pedal. Classic Tube Screamer cut. I requested mine with a blend, which Nick was gracious enough to include. It is a much different voice than the VT and ODB and i'm very proud to own one.

I kinda don't want to see too many in production for selfish reasons though. But if you can get him to build you one, I'd say it's a great investment. It's a real bass tuned Tube Screamer that just kills.

 

[2010P]

The only builder I collect is Dunwich. My collection currently includes

Shalashaska Bass Klon
ODB 125b
WF 125B
Volt Thrower big box
Bass Overdriver
Different OD

I stupidly sold a VT125B and would love to buy one back.

 

[monsterthompson]

Probably gonna regret this, but I’m thinking of letting my DA120 and HM2 go. I’m looking at some synth hardware and I’ve got space and $ considerations to keep in mind.

I have to cop to my ignorance and admit that I have been faking that I know what it means when people say the 18v on DA's pedals allow for more "headroom."
I thought it meant more total volume, but I think I am wrong about that. Can someone educate me on exactly what "headroom" means in terms of 18v? (In layman's terms please.)

The circuit can get louder before it distorts. More clean, less distortion than the same settings at a lower voltage.

So if I want more grit out of my ODB and Bass Overdriver without increasing volume, because I'm not using tubes and don't have a "front end" to "hit", I should run them at 9v?

yes, it's subtle though. i find the character of the distortion changes. at lower voltage the distortion is looser and more blown out. at higher voltage the overall sound is more defined and crunchier instead of broken speaker fuzz

idk about the bass od, but the odb has an internal pump charge so it's running at 18v from a 9v source

Or from 18 to 36. Same with the VT. I think others have this feature as well.

sorry for the delayed response but yes it has an active high pass EQ. Its at a higher frequency then the treble control.

The pedal can amplify a signal to a larger voltage level before it gets clipped by the active devices. Ignoring the clipping that is created by the diodes in the circuit, the op amps headroom is limited by the supply voltage primarily. In an ideal world, the op amp would be able to output a sine wave with amplitude equal to that of the supply voltage (in practice, the actual value is limited by the internal design as well as the supply voltage). Having a large supply voltage means your signal can be larger before it will be clipped by the op amp itself.

Most of DA designs have the pump. When I say "9v" or "18v" I am referring to the initial power from the PSU.

You could do that, or even maybe sag your voltage down to like 4-5V if you could do that. Not super easy for most people but yes as you dump it down your pedal will start to lose headroom.
