Multicab SIM..my own design cabinet simulator .. it works!! cool!
« on: September 01, 2008, 11:23:36 AM »
Im so proud to present to you the Multicab Sim cabinet simulator..

here is the soundclip:

http://www.goear.com/listen.php?v=bec1880

setup: squier strat, burning crunch, multicab sim, sound card

Till 0:30 the multicab sim is off, then, i put it in, and wow!!
check the last seconds.. really cool cabinet simulation..
check the variety of kinds of speakers it can reproduce..i absolutely love it!!

this is the final schem:


NOTE: the opamp is a dual TL072/62/82 ,theres no 4558..

adding a volume control is not a bad idea..im happy with just the gain control...

looks like you are only using one of the 4558 opamps. could you not use the other portion of the 4558 for the section you used the tl062 for?

Oh sorry, both opamps are a tl072..one design goal was simplicity, and the fewer parts possible.. 1 dual opamp and 1 transistor is enough for me..

Excellent work Daniel - it looks pretty simple yet flexible. Yes?

When I recover from my submini tube fetish I'll gives this a go...........

I forgot to post the frequency response graphs:

This is the variation of the low end response


This is the variation of theMid response (actually is centered near 400Hz)


This is the variation of the high end response (is little, but if affects a lot of the tone texture and harshiness..)


all the possible variations:


the final design has the mid scoop around 400Hz and more pronounced..but this may give you an idea of the flexibility it has..

I really like it. Sounds very flexible! You should be proud of this project!  ;D

God i am proud!! it feels so real when playing through my hi fi, like i feel the cardboard of the speaker movin when i play with the mid scoop..

i cant wait to design more fxs and share them with you guys! Im starting with a couple of CMOS inverters boosted by a BJT with pre and post eq..
By the way, CMOS inverters seem to be very good filters for other cab sims..maybe the noise can be a problem..

Great Work !   I went canoe camping for three days and I am glad that your post is still there.  I was thingking of it while there were no fishes   ;D.   Happy  that you're proud of your project Daniel !  When I will try to build myself a cab sim I will consider yours.

The before/after clip is really a good demo of what a cab sim can do for you. Good job!

im thinking of adding an XLR balanced output to it, do you think it worth it?

Might I suggest a BBD splitter to create a stereo spread?

Depends on if you need it for your p.a. I just used 1/4" jacks on mine, no problem.

like adding a mn3007?
it would be nice, but a little over my head..

or is a bbd splitter something simpler?

(Sorry, too late for an edit.)

I just realized this wasn't very clear.

What I meant was- If you need XLR for your p.a., mixer, etc, then go ahead and add it. If you don't need it, don't worry about it. Most mixers and etc will accept 1/4" inputs as well.

i know most PA accepts 1/4 plugs.. but for long cable runs, i dont know if  XLR are a MUST, since they cancell out noise
