Ohnoho's Blowing Up type effect??

What a beast! Right, so i want that sound, that ridiculously angry messy sound. Not too sure how to go about it. I've been looking at a few loud boosts, the Super Duper 2in1 in particular, cos it seems to be the "closest" even though it still isn't close enough.

Now before i start breadboarding silly ridiculous amounts of gain, I want to make sure i get my typology and theory correct. In order to get that really loud angry messy overclipped type sound, is it basically just boost > boost > boost > boost > boost > boost > boost etc etc etc, untill it sounds messy and angry?

edit:
ah!! In an effort to figure it out, i was messing about with Guitar Rig 4, and got there like this:

so my new question is, is there a real-life equivilant of that orange "Gain Booster" component? each one is +30db of boost, so i need ~60-90db of boost. Yes i am well aware that is insane. That is the plan.

?

dont think so. There's a different component for the orange squeezer compressor.

I'm thinking it could be done with 3 mosfet boosts cascaded. Want to keep this one small, and the smallest Mosfet boost schem i could find was the SHO. Problem is, according to the interwebs, it's only outputting about 15db. So, what would i need to change on the sho schematic to output more like 30db?

The software's "limitations" is they key to your sound here - software equivalent of clipping in a amplifier with too large input signals. Ech, that's hard to find in an analog equivalent cause you don't really know what the software is doing.

The way you make the boost pedal will change the sound a lot - and the way your amp handles huge input signals. Alot of variables. Likely that the demos you hear of people playing these boost pedals will sound very different when you use the same pedal through a different amp. Might be more sensible to make a distortion/fuzz pedal that gives you something approximating that sound without increasing the signal strength to enormous amounts... More reliable between different amplifiers and would play a little nicer with them?

ok, so what about if i did something along the lines of the Super Duper 2-in-1?

Lets look, for example, at the AMZ Mosfet Booster. That claims that it can boost up to 35db. Good start. So is it possible to tweak that to output 40db, and then cascade a second (kinda like the SuperDuper on mega max for both) and then use a volume control at the end? Is that possible?

[caress]

just breadboard a few boosters and cascade them... see if it works.  it takes all of 5-10 minutes to make a SHO on a breadboard...
chances are you will run out of headroom at a certain point and get some hard clipping.  perhaps try boosting the voltage up for a bit more headroom?  90db boost though?  seems a bit unnecessary...

or just build this:

I'm not sure if I have the correct sound in mind but if I do Would achieve it by using some kind angry fuzz into an overdriven amp. Or fuzz with some other booster or distortion.
Try a tone machine its a pretty trashy sounding fuzz.
Maybe get a sound clip of the sound you're after.

That's exactly what will happen. Like i said, in guitar rig, it went from clean > boosted clean > over drive > VERY overdrive > OH DEAR GOD!!! > Head successfully asploded

I'm after that asplosion stage. and 90db unnecessary, maybe, but in this case, it's not. It's exactly the kind of dirriculous madness i'm after.

Just build a booster, any booster it doesn't really matter which, turn it all the way up and feed it into your fuzz/distortion/overdrive pedal of choice, that should get you the sounds in that video.

Two suggestions to look into. Firstly have a look at how Zvex cascades SHOs in the super duper, the box of rock and the box of metal. Maybe try them with without the tone controls. Secondly have a look at the likes of the Ruby amps and the DAM sonic titan, ie pedals/amps based on the LM386. Although you'd probably want to ignore the nice preamp type circuit at the start of the lm386.

Think I might breadboard up a sho/mosfet boost into an lm386 and see what sounds I can get.
