simple R/C timer circuit is here - http://www.electronics-tutorials.ws/rc/rc_1.html

Then into a tranny switch. Never had to do this, but just thinking about it from fundamentals. There's probably an easier way to do it, so hopefully someone else will be along in a moment to improve on it.

LPB-1 squeezed into a 1590A enclosure:





It works well with guitar, really pushing the input to a valve amp and working well into a tubescreamer and American Sound pedal. With bass it's good, but overloads on a heavily hit bottom E.

I really don't like working with 1590a enclosures, I've done a few true bypass loopers and buffers in them and thats about as much as I'd want to do.
Checkout some of the MadBean & DIY pedal forums, some amazing work on there, one guy did a Klon clone in a 1590a, ridiculous:

Somebody on one of the diy forums did a mutron filter clone in a 1590a. Mostly surface mount components. That was just nuts!

I like soldering up circuit boards, but I hate the wiring side of things!!

Knocking up my Devi Ever Soda Meiser. Signal goes all the way through the circuit, into the volume pot but nothing comes out.
Checked the pot and it's fine.

Viewed from the underside: signal goes in to the left leg, out is the middle and ground is the right.

anyone have any ideas?

Can you point me in the direction of a simple timer circuit and / or transistor switching? I've not come across either.
Many thanks for the reply

For the timer, look into the 555 timer IC. I think there'll be millions of circuits on the interwebs.

Ah, fixed my problem. swapping the in and out of the pot sorted it.
and there was an ground wire missing from the diagrams.


The 'instructions' that were supplied are terrible.

Just finished an EHX Small Clone (clone). Beautiful, lush chorus.

I modded it by swapping the 150pf capacitor between pins 1 & 3 of the 4047 to a 330pf to make it [i]super[/i] wobbly. Loads of low end and sounds great on t'other guitar too - very 'early Rush' sounding...

Guts pictures or you didn't succeed ;)

Will see what I can do - haven't put the status LED on yet, so it'll have to come out at some point.

This is the Madbean Afterlife Compressor with the 'Ghost Note' sensitivity change mod which basically adds a threashold control. I've put it in an old enclosure I had lying around - I'll get a new one in my next order. I think it's really good with guitar - I haven't tried it with bass as both my bass amps are u/s at the mo'. I put an ultra-bright blue LED in - that may have been a mistake as I can still 'see' it each time I blink!!

I've built one of those before, put it in a 1590A enclosure - fantastic little compressor on bass.
Try a higher value resistor, say 15k to dim down the brightness of that migraine inducing blue LED. Also, I rub those blue LEDs with a bit of fine sandpaper, to take the sheen off - gives effect of diffused LED. Much kinder on the eyes :)

ooo - thanks. Lots of good info there.

Is there anyone on here fancies looking at a Fuzzrocious Dark Driving that doesn't seem to be playing right for me please?

Whats up with it? (as best as you can describe)
PM me of you'd like

Finally got around to adding a blend control to my Zen Overdrive pedal. This is always on for a bit of low gain dirt, but it lost a fair amount of the low end. So for the last year or so I've been using a LS-2 to add a clean loop back in. Now I can just have the one pedal.

One day I'll tidy up the rats nest of wires.

JFET blend. Nice!
[/quote]

Yeah, super simple to knock up. Nice and clean sounding with no loss of the lows.
I can see this being a regular add in to DIY pedals, gonna add one to my Soda Meiser.

Yup, I've made (and still use) a good few of those. Super-useful.

Have you got a vero layout for it? I've been using the LPB-1, but it reverses the phase and, while I have used it specifically for that purpose, it would be nice to have one that doesn't. I assume, because I see two transistors on there, that that one doesn't.

Ah, I was getting my blend and boosts mixed up. That is in fact the blend I use. It's the boost I use to correct phases after pedals that reverse it. Otherwise you get a huge volume drop when the blend is around 50/50. I am building a dual loop pedal which will use a boost to switch the phase, and it will have a switch for switching the order. If it works I may well build a larger one with more loops but without the order switcher.

I wanted it as small as possible, so I flipped one and have them sharing the ground strip.
