I'm looking for an ABY so I can toggle between 2 amps. I want one that:
The Morley is out. They bleed a significant amount of signal to ground. It's like turning you vol pot down by 1/2.
I've been looking at the Radial Bigshot.
Any advice?

Hi,
Have you had a look at these people - they may be able to make what you need
Cheers
Wait for ADR to post his plan for his wonderful LED indicated ABY switch
As I recall it meets all your needs; any tech should be able to knock it together in an hour or so; or an amateur can take a day or two; but with far better satisfaction quotients.
just ordered a ABC switch from loop master, will post my thoughts
I got the Radial, and it works fine. It's transparent enough, no clicks, no hums, and it's cheap. I got the Radial loopbone too, and i can say it's fantastic. I'm less satisfied by the Radial Tonebone Classic, because it really colors my tone.

I was thinking about this one.
Yeah - I saw the Voodoo. Looks nice but it's $$$
graaf: So there's no signal drop with your Radial?
hobie: thanks for the tip about ADR. I'll PM him. I'm pretty good w/ a soldering iron, myself.
It's the schematic for the Morley ABY. See the 100K resistors at the A & B jacks? There's the problem. That puts a 100k resistor between the signal path and ground. Just like a vol put turned down half way. Am I missing something or does that seem like a bad place for a ground? Not to mention a really low resistor value. WTF?
Hey Dave thanks for the schematic! I actually have a broken one of those apart right now but haven't messed with it yet. I'll get it working, remove those resistors and report back here.

Riz: that would be great!
FYI - Morley tech support said some newer batches have 1 meg resistors in that spot (vs. 100K) that should make a significant difference.
Morley also said clipping them out all together won't harm anything.
The thing I find very odd about those resistors it that they are connected to both the signal path and the ground. Compare that to the configuration of the input side. See how the resistor is only attached to the collar of the input jack? That makes more sense to me (given the little I know about this stuff).
I think they were trying to remove some interference/noise from the path. but that's and odd way to do it IMO. Shielded wire would have been better, it seems to me...

Why the buffer? Any time you split the signal in the Y configuration, you are forming a voltage divider circuit. Thus the perceived loss of punch and clarity.
So either use a buffered pedal in front of a passive ABY box, or have to include the buffer circuit if that's all you plan to use.
OTOH, if all you need is AB function, then use the fooltone passive AB design.
Thx ADR: I found the one from geofex from that link you sent to me. The buffer is a good idea but it's more than I have time for right now.
The fulltone box is exactly what I needed. I have all those components at home in the parts drawer (sans LEDS). I can use that til I can find one that has all the embellishments listed at the top of the thread.
No problem.
The "fooltone"?!!!
