A/B Boxes

[medwards1969]

The problem with these boxes is that most have internal buffers that ruin your ability to switch them into the inputs of Fuzz pedals, correct? Are we doomed to the home-made switches like what Eric Johnson uses on his board? Instead of using A/B/C switching like a Lehle he uses two simple A/B switches in series. . .

Does anyone make a A/B switcher that is silent yet doesn't mess up the fuzz pedals if placed immediately downstream.

It seems an obvous problem that no one cares to solve.

 

[Adam Zaiger]

I care! Anyone?

Yes, someone does. I think a couple manufacturers do, actually.

I can relate. I looked all around for a simple EJ-style A/B box and finally ended up buying a few on the ebay internet from a really nice bloke who runs a company called Bristol Audio Devices ([email protected]). I understand they're wired in the same way that EJ's are. I'm using mine as a simple tuner mute box, but hope to someday use 'em in a two-amp set-up. I believe the ones EJ uses are made by Bill Ussery, but I think his old ones were made by Black Cat. As Ryan mentioned, there are a number of manufacturers who make ones like this, like Loooper, Loop-Master and others.

isn't the radial bigshot un-buffered as well?

yes the bigshot is a passive non-buffered unit. great aby box.

I'm interested in the EJ wiring. you wouldn't have a gut shot of that a/b pedal would you?

I'll shoot a pic and post it tonight.

I've made a few AB switches myself. The ones I make are passive without an internal buffer. I can make it for something around $35 with all point to point wiring, and that includes the pedal being finished. PM me if you're interested.

Agreed 100%. Kinda silly, IMHO, to spend the $$$$ on competing products when the http://www.tonebone.com/re-bigshot-aby.htm works so well for around 70 bucks new...

True bypass.
Separate controls for, sensitivity, + output and - output.
This is your "Swiss Army knife" of audio.
list price$139.95
DC jack included (ac power adaptor not included)
current draw 40ma
4.7"x3.7"x1.1"


Two outputs allow using the Launch Pad as an A/B with separate output levels. This also will allow you to drive separate or parallel effects chains with OD pre-driving from the Launch pad

Seems like the ones at www.loop-master.com would do the trick.

I recently picked up an ABY box from Loop-Master ($53). Each amp in use has its own OD box. No problems.

when the box is passive don't you loose some signal?

like its splitting your guitar 50/50 into each amp if they are both on.

versus it being buffered and kinda going 100% to each amp.

Regarding the ABY, Brian at Loop-Master notes on his site:
"Totally passive, and ultra-transparent with zero bleed-over when in "A" or "B" mode. This particular design uses the "X" pattern wiring for grounding out each unused signal while also providing you with the option of combining both "A" and "B". Run your guitar into two amps at the same time or A/B between them."
