Dunwich Amplification General Discussion

Ever consider trying your hand at a speaker cab sim box? I know the OCSD is pretty versatile for an analog box. I also know the IR market is growing, and the market for analog solutions isn't a big one.

I have not spent a lot of time. Part of the difficulty is that analog sims require a bunch of real-estate or inductors both of which are a pain unless your going to do some kind of stand alone pedal. Not sure how much market feasibility there is for a pedal like that.

But if someone was super hard for one I could help.

Recently setup my recording computer and interface to do some miked stuff:

First take was DA120 OD with a POG2 (on closer to the end)


You certainly have Matt's tone on Dopesmoker locked in.
Have you ever taken a swing at reproducing Al's OM\The Sciences tone? So ridiculously powerful. I'm sure there is some stereo funny business going on with his DS1 and DOD250. He has a POG on his board but I can't figure out where it comes into play.

Apropos of nothing, why don't people get boutique chorus or flangers made? I see a far number of reverb or delay pedals. Are they just not popular anymore? Too 80s? I love the heck out of my Electric Mistress.

Yes I did make one thing called the Cisneros Tone Generator - it was a DS1, DOD250 and a JFET clean blend in one pedal. Might be time to resurrect that idea.

As far as chorus and Flanger go, if analog its going to be a BBD type circuit which is costly to make and requires a bit of knowledge. If its digital you need a good programming skill set to use the newer DSP chips. Those 2 tend to weed out builders. Plus they are not as nearly as popular as delay.

Yes please. "The CTG" just rolls off the tongue. I would almost certainly snag one of those. Do you have a prototype or example of the layout & controls?

I think it's this: 3 volumes (DS1, DOD250, JFET clean blend) and a LPF and HPF - I might be wrong though.

I think I remember seeing it a long time ago when I first started looking into DA pedals. I wasn't really clear on what is was.
Since I have nothing but down time, and two amps, I should mess around with stereo distortion. I don't have a tube amp, and I bet that is part of it.
What is crazy to me is that Al didn't sound that great in Holy Mountain or Dopesmoker. It was only in the last 10 years that he has really started nailing that tone. He has had the same equip, so it is either his use of it or the recording engineers that got it right.
@bassboysam BTW is was a Bass Player article about him where they said he used flats. That came up somewhere else.

maybe at one point but all the recent pictures show strings with no silk. i don't know of any flats with no silk unless he has a stash of old fender flats or goes through the trouble of removing the silk. earlier pictures show red silk so if he's using flats they could have been rotos.

There isnt any photos of the unit. I would be re-designing the layout a bit.

Basically the pedal takes your signal and splits it 3 ways. JFET, DS1, and DOD250

The DS1 and DOD250 are pretty much stock except I added a simple low pass tone control to whichever of those 2 designs does not normally have a simple tone control.

For the re-design I have the JFET section setup as kind of a simple cleanish preamp signal, JFET gain stage - Bass Control from Matamp, - Gain - JFET Gain Stage. I would make the Bass Control only be able to boost by adjusting the circuit such that you can never cut any bass. This preamp section would act as the low-passed clean blend signal line

All 3 of those outputs run into a mixer to add them all together. Some phase compensation is made to prevent broad phase cancellation.

Id expect with enough luck that it will be an 7 - 8 control 1590BB sized box.

Wow. Is this (would this be) a thing where one can kick on the 250 and DS1 separately and/or together...ly ?

It would be fairly trivial to allow for on/off settings as desired. Beyond a global bypass you could have 2 stomps for each distortion circuit but leave the clean signal on at times. The only issue comes in is the enclosure size, if you need 3 stomps total then it would be bumped up to a 1590XX box. Else if you kept it in a 1590BB it could have global distortion on/off together.
