Loop switcher ?
Post by hellboy on May 29th, 2010, 2:38pm

I use two heads and one cab. I use a Radial Tonebone tube head switcher and it works great.

I would like to be able to swap the effects loop from amp to amp also. Any D.I.Y'ers ever try this? Plans or schmatics would be helpful, or does somebody already make this ?

it would take a simple switcher from both amps loop send to both amps returns (a 3pdt switch, 2pdt if you don't want an led indicator). doesn't sound difficult, but i'd be worried about the single cab with an amp that doesn't have a load.

I've been wondering about this, how does that work? Does your speaker cabinet need to have two 16 ohm outputs? Or do you use the two 8 ohm outputs that normally come with a cabinet and select 8 ohms on your amp heads? Is it that simple? Do you need a specific switcher?

If your asking about the Radial Headbone? It's completly safe. The head not in use is under a dummy load.

"The Headbone's internal switching comprises a sequence of relays, photocells, and load resistors, all of which are controlled via a digitally programmed chip. Hit the footswitch and the Headbone toggles the guitar signal from one amp to the other, disconnects the speaker and diverts the signal to a load resister, reconnects the speaker to the second head and turns on the guitar, all in quick succession. The Headbone features SafeMode™ whereby even when power is disconnected; the Headbone will automatically default to 'head-1 to cabinet' status, ensuring a constant load on the amplifier."

Check with Shark Diver. He works with Dave Friedman of rack systems who is arguably the premier person to get this done. Not the only person that can do it but certainly a contender for top dog.
