Stupid question... How did Crumbchildz become the "Author" of this topic thread? :scratch:

Probably a database burp ;) Sometimes stuff like that happens during maintenance. The weird thing is that your user ID's aren't even close :scratch:

Yeah, looks that way :hmmm: maybe they should be added to the ass end or better yet a sub-thread..

I need some help does anybody know what kind of switch is the gate and thrash switch. Are they on/off or on/off/on

Dude, please... yeah I merged the threads, and you are absolutely right, that first batch of post contained no info.
Wish I had time to go through the other 23 pages of replies...

I finally got around to building one a little while back. I prefer having the gain lower than what I imagine the average (metal playing) user might go for, and I built this to the Tight Rock specs.

When used in this way, I think the higher voltage is almost a necessity, because it seems to eliminate unpleasant higher order harmonics (that seem to be coming from the op amps themselves). For super heavy distortion, I don't think there's an obvious advantage to anything higher than 9V - you'd really only need it for playing stuff that had a big dynamic range.

It really does seem to be a cool pedal. My only complaint is that when I roll down my guitar's volume, it sounds like a sitar, or like there is a biasing issue. I wouldn't be surprised if I had a minor error in my build, but it would have to be minor, because the pedal sounds great otherwise, and I only run it at 18V with the gain low. And since the gain is never set high, I was able to remove the gate altogether.

What about this on a 4 position rotary switch? I don't want any of the lower gain modifications of the TR version, just more mid range.

Hi everyone. I've read through this thread and while I saw plenty of artwork, I was hoping there would be an Eagle layout to share. Anyone? I'd like to send this sucker to Oshpark since my PCB efforts tend to rust everything around me. Since they have a 3-board minimum, I would most likely have a spare board if someone needed it.

I have heard it mentioned in this forum that you can build the Tight Metal and Tight Rock from the same layout, but with different component values. Does anyone have the component values of the tight rock (or a schematic with values)?

Hey Mike, have a look at J0K3RX's post here:

Nevermind, I missed the fact that J0K3RX posted his DipTrace file. Thanks man! :-)

Yeah, sorry man.. I've been busy lately and didn't check fsb to see if there was any activity. Been kinda dry around here lately as far as any high gainers go so, I kinda shifted my attention elseware. I really wanted to get a (correct) schematic for the Friedman BE-OD pedal but, it kinda died off and went into guess/speculation mode.. Hopefully somebody will get hold of one of the pedals again so we can connect the dots/fill in the blanks..

J0K3R!
Great stuiff and great your work.
I've been doing on your circuit on layout brejna
And now I think how to fit into the housing DOD Death Metal. Sorry for my English :oops:
