Just ordered a Fender 65 twin reverb but I'm wondering if it's possible to run a signal through 2 of the chanels at once I.E


Guitar---->Delay output 1(slight delay)---->pitch shifter---->input 1 of amp
l
l
output 2---->input 2 of amp

So two signals from the same guitar are running at once? Does anybody know? I don't want to fry the amp but have tried this through two amps and it sounds great.

I think it should be fine. I've used all 4 of the inputs to my Vibroverb at the same time.

All four?? Thats impressive.

Well I hope you're right I don't want to fry it. Maybe I'll try it on low volume first just see if the sound quality is there first and not fuzzing or anything.

Anybody else done this through a 65 twin though? Just thinking the circuit will be different thats all.

I've played 2 instruments on my BDRI which has two inputs.

I've wondered what would happen if I were to run the instrument cable
into a Y splitter and have one side go to one amp and the other to a second amp simultaneously.
Anybody know??

The TR's channels are wired "out of phase" (as are most dual-channel Fender reverb combos). No harm will occur when channel jumping but the tone will suffer and the perceived volume will be decreased.

To do this correctly, get yourself a Radial Tone Bone A/B/Y footswitch. This device permits selectable control when using two channels of an amp or conversely two independent amps. The unit also has slider switches for 180-degree signal phase rotation, ground lift (often vital when using two amps) and an isolation transformer. I use one of these myself to give my vintage blackfaces and re-issues true channel-switching capability and often to run a pair of amps in tandem. It's the best $75 I ever spent on a stompbox.

You better pray to your god that both amps are identically polarized and grounded.

Bad idea, huh. Someone went to meet their maker and someone else lived to tell the tale.

Would what you said about the tonebone accomplish the objective I was describing?

That "someone else" was Keith Richards at the Sacramento Municipal Auditorium in 1966. I was there. And it wasn't pretty.

Stay alert, stay alive. Please.

I'm 40 years old. I'm a grandpa and have over a million truck driving miles behind me.
Also, I've grown up around electric motors and machines.
I'll certainly be alert.
Alive? I have diabetes and heart condition that requires that I have a pacemaker which I do not have after being informed 6 years ago of my condition. My own body is the biggest threat to me.

You're preaching to the choir......my "carburetor" has been bionic for six years now.

Just be careful!

Yes you can, all you need is a Y cord. One thing most people don't know is you can daisy chain the channels and use one channel kind of like an FX loop, and adjust the tone and volume for each channel different. I did this all the time with my Twin back in my gig days. I would plug my guitar into the vibrato channel #1 and then go from #2 to my delay and into the #1 normal channel. If I wanted to I could even daisy chain several amps together. Just think about daisy chaining 4 Super Reverbs together, I did that. There are some real cool tricks you can do with a Fender amp.

Is a Y-chord not technically the same as running a 2 leads from the same delay pedal though effectively??

Here's an update on the twin situation: The amp arrived last week. Turned it on and there was a intermittant buzz from the amp-quite loud too and within a few mins I smelt a very mild burning smell. I assumed the smell was maybe ink from the logo on the tubes burning off or something so dismissed it anyway I carried on playing.

After 10 mins decided to go through both channels at once. The sound was awesome (besides the intermittant buzzing still being present). Sounded super fat whilst still being clean-I nearly wet myself it sounded that good!!

After 30 mins of playin I decided to put it down for a bit. Hit the off button and saw a flash from the back of the amp and the amp was dead!! I don't think this is anything to do with running both channels at once though as I could smell the burning before I plugged in both channels. Its being returned to the shop today via UPS and they're going to send another out as soon as they recieve it.

Although to ask the same question as before:
"Is a Y-chord not technically the same as running a 2 leads from the same delay pedal though effectively??"

Anybody???
