Help me design my Dunwich amplifier

[amnesiac305]

Wow..that looks really sweet. I think that is a perfect amount of controls allowing for a lot of tonal changes yet not overwhelming. I do though like have two inputs, one being attenuated.

[DarkAxel]

super nice

I, myself like a bit of extra controls... but in the same way I really love the controls on my Elements

to carefully tailor my sound exactly as i want it and leave it forever

here is the first design I came up with for Dan



I figured I can share this since we are making it a public discussion on this amp.

Wow dude, thats beautiful.

probably go through a few iterations but thats the first shot on the design, see what dans says when he gets his irish ass up and checks it out

oh yea FYI, dashed lines are knob outlines. In the final product I wont likely have those there.

They're ahead of us, he's been awake for hours.

He's probably busy working to pay this Dunwich off at some point.

Hopefully anyways as it's half three in the afternoon here.

I should explain those switches. The idea in this amp was to get both Marshall and Matamp type tones. To get a marshall-esque tone you kill the first EQ (its a james/bax), engage the second EQ, put the Bright and Tight switches on. That would be pretty close to a 2203 type preamp. You basically cut some lows early, peak treble across the interstate resistive dividers and run a FMV. To get the matamp-esque tones you run the EQ1 on, EQ2 off, Dark and Fat switches on. Now that has full range of bass early in the amp, no treble peaking, and lots of low end gain with a james/bax EQ.That would be close to the basic Or/Mat type preamp with a bit more gain on tap from an extra stage of gain. Of course with all those switches you can get lots of inbetween options even running both EQs

Now there is another little detail 2, the gain knob is a dual gain knob controlling the signal level between 2 different gain stages so it has the ability to have a very wide sweep of gain from what I assume is pretty pure cleans to pretty heavy distortion (little more than average 2203 and Orange/Matamp)

That EQ design is fantastic! Talk about a versatile little combo, wow!

[new05002]

the EQ selection will be footswitchable but the other toggles wont at this time.

That train is sexy, it almost hides the fact that the amp has MV.

2 Master Volumes

post phase and pre phase. Not a big deal, sort of a given on a bedroom rocker or where you need lots of control.

[D.o.S.]

... you should build a phase 90 into EQ1 and a Small Stone into EQ2.

Swirlie sounds forever.
