Oh I caught that right away. Really nice job as always.

[squirrels]

Thanks. I hope that one makes it to the show.

Building this, just checking to make sure I understand:

If I'm using SPDT for the switches, they would go to the outer lugs with nothing connected to center?

To make this more bass friendly (I haven't built it yet, so it may be fine as-is) I could tweak the 1uF from the input?

[squirrels]

One to an outer lug and the second to the middle.

Thanks squirrels.  Still using this pedal?

[squirrels]

No problem. Yeah, I wound up hardwiring the switches to be permanently on and rehoused it in a 1590A. I found it kind of boring with the switches off and without the starve engaged. I saved pedal board space this way too.

Newbie question: how do I add led to Starve footswitch? (going to use 2pdt)

My 2nd try of etching:

You can wire it just like the bypass led in the offboard wiring diagram.

Use pole 1 (lugs 1-3) for the starve pot switching, and pole 2 (lugs 4-6) for the led: V+ to clr to led anode. Led cathode to lug 4. Ground to lug 5. Lug 6 can float or jumper to lug 5.

Javu - what method are you using to etch? That looks awesome.

[javu]

Thanks for led tip!


I followed these instructions, just used pcb toner transfer paper instead of photo paper:

I replaced 1uF electrolytics with non polarized tantalums. Should this be ok? There's something wrong with my build. I do get distorted, "violin like" sound but starve pot or switch does not affect the sound at all. Switches also seem to do no heareble difference. Texture pot changes sound radically when turned to about 1, after that sound stays about same whole range up to 10.

I measured resistance from 9v power to 9v input in board and it seems to work ok, switch and pot are doing what they should.

i never heard about non polarized tantaluns. Just curious!

My bad, I meant multilayer monolithic caps. :)

Anyway, there was microscopic tin bridge. Some razoring and it works like a charm :)

Boxed it up.  The switches are odd.  S2 I think is working correctly (the D2 LED lights up when engaged), but the effect is not drastic.  S1 does not cause the D1 LED to light but almost doubles the gain/volume out.  

I need to verify what exactly is doing what tonight (I may have the switches backwards, it was late when I was looking at it), but is that how the pedal should function?

Awesome, ive had a buddies' shiva for a few years that i really need to return. is this definitely verified?
