GK rails in a pedal?

[rolandm]

Another reason to buy one of these, is the cool factor of that faceplate. Very cool look. FWIW, if I'd had 300 bones, I'd have bought your 36o preamp. Just know that your work is appreciated and admired, even though it might not be purchased. Small consolation, I know, but it is what it is.

Just finished a batch pedals for some fellow TB'ers.

So this is probably the only time I'll say this. Is there anyway to top mount the jacks? The jacks being on the outside of a 125b (I'm assuming that's the size?) seems incredibly pedal board awkward. With pancakes I guess it wouldn't be that bad, but just curious.


Also who is selling these? I'm confused about the fuss of "you should buy this only from this person".

Schematic is on page 22

Many thanks for this, completely missed that.
Again, apologies if I've missed this, but what does the Distortion Detector part of the Schem refer to?

Many thanks

Would be great if someone could update a post in the first page with the schematic and latest clips!

it's in a 1590B, not a 125B, and there's barely enough room to fit everything in it as it is, so top jacks is not an option.

The distortion detector is an optional circuit that lights an LED to indicate the onset of clipping on the output drivers. It isn't needed for the pedal to function properly.

Here are the other schematics:

Ah gotcha. Just looked back and saw your gut shot. That is incredibly tight.

Still interested to hear what this sounds like through a tube amp if anyone has made a demo.

A big shout out to Frank from Fea and John K for all the hours and effort that went into this..... worth every penny to support projects like these....

Count me in on anything you guys decide to do..

If I've offended anyone, I sincerally apologize. That was not my intention. If John and Frank wish for me to stop building these pedals, I will oblige.

how much do these run?

Perfect, thanks so much!
So that trace effectively travels from the R13 junction down to the boost circuit (or C3) if the detector isn't implemented?!

Great stuff, popping this into Eagle when I'm back from NYC next week

Thanks

Thanks! It was a lot of fun to do this.

I am not building these and the schematics are public for anyone to use.

If it weren't for John prototyping on the west coast, while I was making his life difficult with circuit changes from the east coast, this would have never made it to V5. I have to give huge props to John or anyone else that is willing to play and go the distance with me!

No. If you do not use the detector, just leave the "Y" and "Z" connections open. Think of the detector as a crude voltage meter...

[loveandbass]

can i get a ballpark $ for these?

PM a builder: domdec314 or johnk_10 are two in this thread.

I have a few questions...

I've scanned through this thread but haven't seen a sound clip of the effect. Did I just miss it? I'm wondering if it does pretty much simulate the power amp signal hitting the supply rails? My concern is if it would allow a MB amp get that classic GK hard driven sound.

I'm also wondering about kit versions. Are kits with empty circuit boards, all necessary components, cases with artwork, knobs and such available or is anyone considering making them available? I'm thinking like a kit version requiring the assembly and soldering work.

Sorry Frank, I'm going to ask for you to elaborate here, I'm still early in my electronics knowledge .
By 'leave Z & Y open', do you instead mean that the output of the boost goes straight to R10s junction and the R13 junction simply straight to pin 3 of the IC?

Again, sorry if I'm missing something basic here

Thanks
