Barber Ltd schematic

[seljetnoma]

Hi,

I'm looking for a Barber Ltd schematic.
I would like to do some mods on my unit and a schematic for reference could be handy.
So if anyone has it, are you willing to email it to me?   ( seljetnoma@hotmail.com )
Thanks a lot in advance.
Kind regards,

Sel

Dave's been good to us here, so it would be out of keeping for a schematic of his to be posted.  On the other hand, he appears to be VERY approachable, and fairly mod-minded himself.  You might simply try dropping him a note, outlining what it is you want to try and do and asking which component changes might lend themselves to that goal.  He strikes me as someone who very likely thinks beyond the boundaries of his own designs, so he might have even already pondered your question before you did.

Have you checked the Barber site? He has some mods there for a few pedals, maybe LTD is one of them.

Hi,
Thanks for your replies.
I understand that Mr Barbers schematics can't be posted here, I totally respect that, that's why I asked to have it emailed.

All kidding aside, well I checked the Barber DD and saw that the pcb layouts are somewhat similar, which made me think that with a few twists I could maybe make it switchable between std Ltd and (somewhat) DD like.
I know the gain is way lower on the Ltd, but since the DD has the 2 diodes from signal to ground it acts basically more like a distortion, so I thought I could maybe add the diodes also to the Ltd to experiment with od/dist. like sounds.
I checked the Barber webside and checked the mod section, but it's mainly about DD mods. ( which is cool BTW )
Anyways, thanks a lot.

Since there are 2 versions of the Ltd, I wonder what the main difference is soundwise between te normal Ltd and the silver series Ltd.
Anyone compared the 2?

Thanks ,

i've had the silver for a while and just picked up a black last week.  the black has more mids and sounds fuller and thicker, but otherwise they're very similar.

Dave's got a profile here and I've PM'd him several times. VERY nice guy! I'm sure he'd be happy to answer your questions.

The Resistor below the bass trim pot sets the midrange, you can add a trim (20k) or just replace with a value you like (1k-20k). You can pop strings of diodes across the drive pot legs to tune the clipping you like, the stock clipping is (2) 1n4148 in the feedback loop, if you want a more dynamic sound with a little more clipping from the op-amp (harsher too!), just snip the diodes from the left side of the op-amp and apply your own recipe across the drive pot legs (outside legs please), you could even wiggle out the mica cap and pop your own value of feedback loop tuning. I would not mess with the recover amp too much (other than midrange) the beauty of our pedals is in the clipping tuning and that RIAA style recovery we use after the clipping stage (like on old magnetic phonograph!).

You can go high gain by lowering the value of the 13.3k resistor on the bottom left side of the PCB and pumping up the value of the associated cap
(.02) maybe go for a 1k and .22 combo for some extra fire!.

The tone stack is a little tricky, so maybe start with what I have detailed first.

Dave, Dave, Dave.....

I never doubted I'd see this note for one minute.     Let this thread, and its conclusion, be a template for those who ask similar sorts of questions.

You know, sometimes, just sometimes, it IS possible for designers to take pleasure in customizing their product for end-users without revealing too much or feeling cheated in the process.

I never lost faith for a minute.  I hope this thread increases the faith of others.

Dave Barber is exactly the kind of commercial pedal maker who fits right in with the feeling and ethos of this community (not that there aren't others). Great guy.
