My own FV-1 PCB, work so far

[MetalGuy]

with the addition of the external eeprom i think this chip has huge possibilities and my next step is to get the smartcard bit assembled for this.

Why instead of external cards not use a uCU and load several sets of effects into it's memory and then select between them (the selected one will load into the external EEPROM)? You can go even further and can make it memorize pots settings for each effect and add 7 segment display as well.

Thanks for the idea. I had thought of going that route by replacing the pots with something similar to the TC9170ap chip (voltage control ss pots) and use a uCU to select patches and all settings stored like you say, but in all honesty i have no real or recent PIC or Uc programming experience so would find this a really steep learning curve. Great idea for a future build though.

Glad there was no damage to the FV-1 and the board came up!

I got back to this today after a few problems with the 3.3v and ground being shorted. It looked like one of the pot connections was causing the problem, anyway i have sorted that out and was hoping there was no damage to the FV-1 chip.
So new battery in hand and i plugged it all in and to my amazement i had a working reverb. The onbaord sounds are really nice , the flanger can be made to get that Van Halen sound easily , chorus is nice and crisp is perfect for the "nothing else matters" intro.  Pitch shifting is truly weird, (+/- 4 semitones) .

I don't have a recording set up at the moment but i will set something up to get some sound clips as this report is pointless with no sounds to check out.
I can see this prototype going into a little practice amp i have planned.

Thanks go to Frank for all the info and help !!

I just wanted to post a couple of sound clips , nothing much really

setup is basic,  Guitar into FV1 circuit direct into cheap usb sound card on PC. (not the best way to record guitar, I will mic up my guitar amp when i can think of some proper things to play to demonstrate all the FV1 effects later)

Clip 1. Chorus and Reverb. - 1st clean       2nd chorus          3rd chorus and reverb
Clip 2. Tremolo and reverb -
Clip 3. Echo -             same riff played with slapback echo and long echo (

I'll try and get some better examples also for the pitch shift and flanger.

that really sounds grate. I have to order one of those and start building
