Peavey F800B Preamp PCB

by **ryan_biggamepedals** » Sun Sep 11, 2016 4:26 pm

Hi, I made a run of pedals that were derived from an early F800G Super Festival amp, and I have some pcbs left over. Anyways, if you're interested I'll put a link to my site. they are $11 and I put up a build doc and drill template. Here is what it looks like, but its green, and the trim pot is a bigger 9mm one. Also it doesn't say all that stuff

Ordered 2.

One to mess up, one to get right!

Haha nice! I was pulling my hair out trying debug a couple of these guys. Just watch your electro cap orientation and resistor values and you should have two working pcbs!

Just got two.
Should make a good Christmas present for someone if I get off my arse and built it.
And then one for me!

I can trade you a fuzz factory PCB for a F800G PCB its like the same price almost on my site.

Question for ryan_biggame, is there a way to add switch between clean and dirty gains, like add a footswitch and have two gain pots?

Sure, shoot me a message and we can work something out

Yes, but the volume just from clean to distorted is pretty massive. What you can do is disengage the gain pot and use two volume controls. It's not super easy with this pcb, but I can send you a schematic if you would like.

That could be rad!
Thanks man!

took me a few minutes to sort out that you actually wire the jacks to the PCB then PCB to footswitch then back to the PCB then back to the footswitch then back to the PCB then from the PCB to the jack.

really need a build doc here anyone have it?

Sent you the build doc, but what? That has me all confused.

Maybe that's what I messed up in my build, but I don't think so.

I wired jacks to the pcb up top, and foot switch to the connections on the bottom.

yeah but if you think about it the signal goes in an out of the PCB two extra times compared to most other guitar pedals. makes the wiring cleaner maybe but I actually think it just makes the build more complicated. I got the PM thanks.

can I use max1044 instead of ICL7660?

by **eatyourguitar** » Mon Oct 31, 2016 4:30 pm

I found 7660 on mouser all set
