Guitar Splitter / Phase (Help! Newbie!)

[weston530]

Hey guys,

Im not very good with this stuff, but I have soldered a few things here and there. Built a simple crossover. But I am not going to attempt to make this guitar splitter in the link provided. I understand the schematic and I was wonder if anyone could give me some advice to change a few simple things;

a) I would like a phase revrese switch on every isolated output, now i dont know if that is as simple as making a switch with a seperate circut that just goes through an op-amp (-), or something. I cant quite find the answer on the net.

b) If I could somehow use a power supply from a universal dc type thing ie)9v.. 12v that mite be easier for me.

c) This is getting greedy but a trim/attentuator on the isolated outputs would be nice, but this is totally optional.

Im not expecting anyone to send me a schematic or anything crazy like that, but even if u could push me in the right direction or website. Any help would be appreciated.

Thanx,
-Dan
