How do I make a digital switch for an fx pedal?

I need to use that instead of a simple toggle switch.

What does your psu's look like? I've surfed around the net, looking at different peoples take on this. It seems the amp is quite sensible to this.

BrianGT uses those diodes in his psu, but I can't find them here (Denmark). Can u suggest some good alternatives (also to the circuit)?

I'm fiddling around with the lm386, seemingly learning a lot  :lmao:

I stumble across this thread about valvestating the lm386 (one of ardrics posts, it has a link) , but i don't really get it. Could anyone explaine?

Thanks 

I've been looking at different versions of the lm386 amp. Is it possible to put fx. a fender or marshal tonestack in there, without loosing the nice overdrive u can get with the circuit? The Noisy cricket does have a single knob, but I would like more flexibility.

ROG have a version where they use the fetzer circuit, but if I'm correct that is higher gain than the circuit in the ruby and noisy cricket. How does that affect the sound?

Could you fx. put the tonemender from ROG in between the buffer and the lm386?

Hmmm... I guess this shows quite a lack of gain knowledge on my side

...on that note, how do you calculate the gain loss of a tonestack? Could it be done in either Tina Pro or ltspice?

Question from newbie (with a big N) 

I'm looking at the poweramp part of the Dean Markley k-150:

- What kind of ic is ic5?
- what does it do, is it a buffer ?
