Hi John, based on yesterdays brief practice session, I think it will be exactly what I need forJ my pub gigs, but i'm at the Merseycats Jam night Tonight(which will be a good test & then Friday we're doing an actual gig so by Saturday i'll have a really good idea if the fixed Stage solution is all I need, right now I think it will be. I'm thinking of making it a permanent fixture in the back of my Amp, the case I've used is a tiny bit too deep, but I think i'll be able to coax it in there with a big hammer . I'm also thinking about "hard wiring" inside instead of the y shaped lead, so could I ask a couple of questions ? My reading of the box I've built now is i'm not using the switching(permanently on) & i'm not using the original speaker out Jack, so could I hard wire the circuit in the following way ? wire resistors 3-5-7 to 4-6-8 ?, it looks to me like this would work to by pass the switches in the On position. Also could I disconnect the leads from resistors 7-8 from the original speaker Jack(not now used) & then use the jack for my internal Y wiring ?. I'll report back on Saturday after my gigs. Thanks John. How's the D button idea coming along ? .
