Any cab simulator circuit worth building?

[Willypp]

I used a 1 transistor Balanced driver though, and it works really well..

Got a link for that?

Sorry, I didn't see your post before

I did post it a few posts above, but here it is again. It is very simple. I did increase all resistors to 10K and I am supplying it with 18V. No problems so far

Here's the other Lart cabsim (not the simple cabsim 2) and I was messing around with it a little.. I think Temol built it and provided a sound sample for it also. Anyway, I am am a fan of the Simple CabSim v2 for it's simple design, and realistic sound so of course I'm gonna try the new Lart cabsim

I found that if I bypassed the 2 filters back to the pin7/R12 junction the plot looks almost the same as the simple cabsim v2. So I added the 50k pot so I can fade between the two. The other pots I added look a bit odd alone but all working together should give you some interesting variations. The plots at the bottom show all the other pots set at 0 and then the given pot alone at 100%. The last one VR4 show it at 50% and 100% and you know what 0% looks like from the other plots.

If i change the output caps to non-polarized, will this circuit applicable to phantom power? Or any further modification needed?

found this interesting article on cab sims, with clips....so putting it here...

heres my astro sim prototype...still on breadboard..

i live next to a busy road so mic'ing up an amp is out of the question....its a pain in the ass
so........

Nice try! We know the vacuum of space is the real reason you can't mic an amp up there! 

[deadastronaut]

ha ha yeah that too....in space no one can hear you jam...

So not some noisy old hyperspace bypass?

It is a hilarious coincidence that I am about to head out on vacation, and the one book I packed is The Ultimate Hitchhiker's Guide. 

(And, yes, I believe I have a towel packed as well.)

Rob,

Sounds Excelent! It's refreshing to hear and see somebody actually playing a demo instead of reamp DI tracks... I like reamping but, it can be a bit deceiving.

I'm on vacation right now, so I need to remember to give this a listen when I get home. I'm sure the phone doesn't do it justice.

Enjoy your vacation too, Eric. A towel is all you need. And a wifi connection.

cheers jim, yeah its pretty good...works great for double tracking guitars direct....and bass too.

talking of deceiving, ive been tapping various ''cab sim circuits '' into the NI Multisim '' prog...

and then trying them in a real world situation on breadboard, and to be honest they all sounded really naff...its like the standard  'graph' for these 'cab sims' is way off of what you want to hear/expect....unless my ears are totally screwed...or people like that sound...hmmmm.....

anyway, i'll get my version built up and finally finished when i get my pcb's , i'm pretty happy with it.

others may not be... i guess its subjective...as are ears...

Hi Rob
Thanks
looking forward to seeing the astro sim pcb in your shop!

my latest, astro cab sim. finished up last night.... 

xlr out, phones out, and out....

made a little boo boo, had to run a 100k from the bottom of the board to 2 points..no biggie. sorted.

Sweet! The demo is really nice. Count me in on one PCB at least :-)

[deadastronaut]

will do....

Beautiful work my man, bravo

At the top of page three, in december 2014, I wrote:

For a while I have wanted to build a cab sim and the schematic in Jims post on the top of page 2 seems pretty simple and I think I have all the parts

I made this vero layout in the train on my way home from work yesterday.

Well, I finally built it some days ago (I still had the parts) as I use headphones more often. It makes a dramatic difference when using headphones. As it is my first cab sim I don't really have something to compare it with, but I like it!

I think it's the simplest circuit presented yet. Both my vero layout and the schematic has disappeared from the original posts so here they are again, freshly uploaded to the gallery:





Have fun

For recording direct you will always need a harware analog speakersim - for monitoring. (I started rec. direct in 80's with a aria me30 - a solid-built rockman knockoff - and even built several frontend addons to get more sounds).

Today you will always use impulses in the final mix, but you need a latency-free monitoring sound - which is an analog ampsim territory.
