DIEFET: Jfet simulation of the Diezel VH4

[ech0es]

The DEEP(which was copied at ROG's Thor) section reduces the output volume about a half.

It was not copied from the ROG thor , it was from the diezel VH4 user manual:

5.1.4 Deep
The Deep control is an active bass control for the power amp that adds low end punch to the power amp centered at 80Hz. It does not alter the dynamic behavior of the power



To increase the volume cancel the resistor of 220k with the cap 100p at the output of the pedal:

Hi,
I have build the version 1.21 as a two channel version , see at the link. I create a new layout with a dc/dc coupler LTC1044 for more Voltage. The voltage approx 17V. The tonestack is not good. the circuit is very bassy and has no differnt highs or mids. I still must experiment a little. The whole then shall into a 1590 DD.

ohnoes! link broked

in other news, i wonder could this be built on matrixboard (NOT stripboard). I really want one, and i want to stick it all in a teeny tiny box, like a hammond box. I reckon it'll sound damn sexy out of my Vox amp....

[Scruffie]

And in opposition, due to my love of Strip or Veroboard could this be built on Vero like the torchy Dr.Boogie Rather than perf? I know alot of people hate perf and vero, but I personally hate PCB and Perf, i find Vero so easy, strange i know, but if anyone has a layout it would be greatly appreciated (although i accept it may well not happen anyway but thanks anyway)

Scruffie.

[trad3mark]

I'm assuming that Matrix Board is the same as perf and Stripboard is the same as vero?

[Scruffie]

That would be correct.

[trad3mark]

i think i'll build it on perf tbh.

[Scruffie]

Thats fair enough, every builder has there preference really, mine just happens to be vero (don't have to make PCB's and all the wiring/connections are pre done, just a few track cuts)

[trad3mark]

i wonder would it fit in a small hammond box, like a FF sized box, if i used smaller pots....

[Scruffie]

Be tight but i don't see why not, be a bit like a box of metal inside i guess, have to use very small components too i'd imagine.

[trad3mark]

well ideally i'd like to have small pots (like seekwah small), on perf board, in a FF sized box, with a DPDT switch (true bypass would be ideal).

Although....

Realistically, my setup is kinda awkward to have....

by the end of the summer, my gear should consist of:
Guitar, FF, Digitech Whammy, BMP, Diefet, WahProbe, Amp.

What i want is basically, to be able to switch between a few channels. Something like this:
Channel 1: Totally Clean
Channel 2: FF
Channel 3: DieFet
Channel 4: BMP

The Whammy and WahProbe will be before The channel select. So what i think i'm also gonna need is some sort of A/B/C/D selector box (1 input, 4 outputs where only 1 channel will ever be active at a time and there'd be 4 switches, to activate whichever channel needed) and some sort of A/B/C/D merger after, like with 4 inputs and 1 output.

Ugh... I've so much to do over the summer...

[Scruffie]

Well the Perf shouldn't be too much bigger than the PCB layout, although PCB would be easier other than having to etch it, those pots are damn expensive in the U.K, but you might be able to use the 16mm ones (technically that would only take 96mm and the boxes are 111mm but be damn tight. That pedal board sounds remarkably simmilar to a Mr bellamy...

[trad3mark]

yeah, it's a sort of bellamy-white hybrid... Except i obviously don't have the money to buy half the stuff he has.

[Scruffie]

Hence pedal building, a find money saver.

[trad3mark]

i think the channel selector thing could all be in one box. Have a send and return for each loop as it were, a master input and a master output...

the diefet sounds not very well with a fuzz factory.
The only fuzz who works with the diefet is the nitrogren 21 from jmb experience.
keet in mind that you will not be able to use the FF AND the DIEFET

The inspiration for the Deep control in the circuit may have been from the VH4 user manual, but the implementation is certainly similar to the output stage of Thor. I believe that is what DimebuGG was referring to in his post.

[paengkee]

i recorded my band's tracks with an ibanez rgr320 and the diefet going to a fender solid state amp and mic'ed up with an sm57

no vocals yet. which is a good thing

yeah, especially having the same values....But it doesn't mean I'm criticizing because over all this box sounds really nice for heavy stuffs..

[rrhoads33]

Does anybody know, if there's a PCB layout available, that fits into a hammond BB enclosure or has anybody some eagle files to optimize?

Please let me know, if you have/know something. Thanks!

Found! There was one @ diystompboxes
