Probably like Â£60 mate, I could fit it in a small box if you're not bothered about battery power.

Awesome!

What colours you got knocking about?

Post by **Mike** » Sun Oct 26, 2008 2:22 pm

Umm.. White, Silver, Red, Yellow, Orange, Metallic Blue, Metallic Green, and I'm buying some Metallic Red for Jimmy's fuzz hopefully.

If you have another colour in mind I don't mind buying a can.

Reece · Post by **Reece** » Sun Oct 26, 2008 2:24 pm

Metallic blue would do me lovely.

Post by **Mike** » Sun Oct 26, 2008 2:34 pm

OK if you're serious about going for it I will order parts on Monday, I'm out of cases and 3DPT switches and a bunch of other stuff.

Another thing: are you ok with DC only power?

Reece · Post by **Reece** » Sun Oct 26, 2008 2:37 pm

Yep I only use me powerstation. I assume regular 9v dc centre neg?

Thanks alot Mike!

Projects in the works:

St. Jimmy - Coupletones Fuzz
- with aggressively offensive decal'd control names.
- Metallic Red paint, Blue LED.
- $90 shipped (I believe I said $80-$100? correct me if I'm wrong)
- board built, case marked up and will be drilled on Tuesday

Zaphod - Harmonic Perculator with Tone control
- Added tone control
- Metallic Blue
- Â£60 shipped
- will mark up case tonight and drill on Tuesday.

Fran - switch replacement in Marshall GV-2 Guv'nor Plus

you did say 80-100, so 90 is just peachy keen with me, good sir!

and oh yeah, lol to the Coupletones Fuzz with Aggresively offensfive decal'd control names.

If I could fit it on the box that would be the Official Name.

Are you going to demo the Percolator? Which cricuit did you use? I'm wondering how it will compare to the one I built.

Post by **Mike** » Mon Oct 27, 2008 4:09 pm

I'm going to build it based upon the layout Tim posted. It's going to have an AC128 Ge pnp instead of a 2n404A though. I have many to try out.

I may put a booster output stage in also if it's not loud enough. I can demo it no worries.

LOL. Use a bigger box and charge me more!

Good plan. I was planning on putting teh clean boost before the main circuit, but that will work better. The first one of these I've made is almost done. Re. loudness, I figured lots of people will just use it with both controls up full, so for this first one it can do without extra boosts.

A boost before will most likely just saturate the gain stage, so you'll just have the one gain setting.
I was going to just through a Saltbooster stage in after the diodes.

Looks like there is a mistake in your layout now I look at it:

I think the Diodes should be clipping to and from ground from the end of C6.
And presumably R6 should be from that track to the Output pot.

Can you link me to the schematic you used?

Post by **Mike** » Tue Oct 28, 2008 9:40 am

Found it, and it looks like your schematic is correct. How odd - must be a form of assymetric clipping.

I thought that was the key to it's sound.

Asymmetric clipping is normally done with differenct numbers of diodes in each direction (say 2 down to ground and 1 back up from ground). this is a different form using a resistor.

Ah. Been a while since I've done any electronics so I can't remember anything.
