I bough this for 5 euros , it was supposed to be be stone dead. I did few oscillscope probing and this things came back to life ?!
Funny thing, they used a micro-processor to produce a wah wah ?! 128mA draw for a wah wah ?! An effect that we make since the 60’s with cheap transistors. Weird…
the effect is quite weak. It’s a rotary wah wah , don’t expect much…Considering the price for a brand new , it isn’t a bargain for sure.
