Re: Diezel VH4 Pedal [schematic]

Aha; I knew someone posted a correction a couple pages back: The schematic posted previously in this thread by another member is correct - but as i mentioned R26 and R34 are 1k not 110R. The back to back diodes are 5v6 zeners. It might be a couple days til I have the time, but I'll try to upload a m...

Re: Diezel VH4 Pedal [schematic]

There are 2 mistakes in by BOM above : R26 is 1k instead of 110 ohms, and R28 is 100 ohms instead of 1k There are also a few in 440hz's one, I let you check If R26 was supposed to be 1k (rather than 110R), then the error was on the schematic, not our BOMs. I knew 110R sounded odd. Now that I've tak...

Re: Diezel VH4 Pedal [schematic]

Any more news, bajaman? Still waiting on those boards to come in?

Re: Diezel VH4 Pedal [schematic]

Very cool, bajaman!

If you end up with a spare working board, I'd be interesting in buying one off of you.

If not, I'd be down to split an OSH Park order with someone, if anyone else is interested.

Are those not just your average right-angle PCB mount pots like these? http://www.taydaelectronics.com/potenti ... mount.html

Re: Diezel VH4 Pedal [schematic]

Also, what size enclosure would this require? The 1590BB is the biggest I've used, and those measure 3.7x4.7 inches -- almost long enough in the longer dimension, but a half inch too short in the shorter dimension.

Re: Diezel VH4 Pedal [schematic]

Nice layout! Thanks for sharing. OSHPark's pricing is $5 per square inch for 3 boards. Since your board measures 4.38x4.88 inches, that's 21.4 square inches, or about $107 for three boards. That's just over $35 per board. Seems pricey. Are there any other PCB manufacturers that offer better pricing?...

Re: Diezel VH4 Pedal [Gut shots] [schematic]

kh602, excelent pics! Hate to bother you further but, do those pots have any values on them that you can see without lifting them? I have a few pots like that so I am fairly sure the values are on the bottom facing the board.. We can probably guestimate what they should be in the tonestack since it...
