    I’m on a roll; I just boxed up the Swah (looks like v3B PCB). You don’t know you need an autowah until you have one LOL. Another great sounding pedal, a lot of range in the controls and very responsive.

    I socketed the transistors because I wasn’t sure about my BC550B (Hfe 436, Vbc 679mV, Ic 6.3mA as measured by my tester). My measured voltages at Q2 & Q3 seem a little low (by about .5-.7V) at B and E compared to some voltages Barry posted but the pedal sounds good to me so I’m not too worried about it .



    Very nice.  I think this circuit is overlooked by many.  Personally, I love it!
