    Yeah I'm cheap... What's the cheapest loop pedal around that actually works? Is it the Digitech one that goes for 40 dollars new? The loop lenghth I'm looking for is around 10 to 15 seconds.

    Dunno about Digitech, I had one for two weeks and it used to record the click of the pedal along with what you were playing :meh:

    The Digitech is really cheap indeed but will only give you 4 seconds.
    For the time you're looking for, I too think it would be the Boss RC-2.

    What is the Digitech pedal you're referring to? Is it the X-Series DigiDelay?

    You could clone the ZVex looper pedal for about $20 worth of parts.

    No I'm pretty sure it's not Xseries. I saw it somewhere on the web, forgot where though.. could've been the classified forums a while ago. Or maybe eBay.

    Is it the Digitech JamMan you're thinking of? How would the RC-2 compare to the JamMan - any comments?

    The basic record / playback circuit is shown in the application note I linked. You would probably want to add a blend control so you can mix the input signal with the loop output so you can hear what you're playing. A simple op amp based mixer would probably work just fine.

    The variable clock control could be implemented with a voltage controlled oscillator. Personally, I probably wouldn't bother with that feature.

    Before anybody gets too excited, bear in mind that the Winbond ISD chips have one rather annoying limitation. There seems to be no easy wasy to make them go from record to playback instantly or easily. On most of the chips, they go into power down mode the moment recording completes. It then has to power back up to start playing. Plus, the switch inputs have debounce delays built in. All of this takes time - from what I can tell, at least 100 ms, maybe more.

    It might be possible to get around this problem with the chips that have a serial programming interface, since it appears that the power down function can be disabled, and the debounce delays would not be present. That takes a bit more control circuitry, at which point I have to ask myself whether it's really worth all the time spent putting that together, or if I should just spend the $200 and buy an Akai Headrush instead.

    Here's Winbond's site if anyone's interested:

    Unless you are talking about a bypass looper (which I am fairly certain you are not) you will NOT get a looper for $40 new for quite some time...You can barely get a decent distortion pedal new for $40 these days. The RC-2 is about the cheapest dedicated looper you can get. A Boss DD-20 is about $180 now a days and that will get you 23 seconds of looping time plus a whole lot of cool delay functions. Other than that you don't got much in other options. You can look for the old DOD/Boss samplers but they don't go much over a few seconds, same with the DD-6 and Digidelay.
