So. All this ranting about true bypass everywhere you go. I figured I'd start a thread about it.
First of all, what is "True Bypass"? If I haven't got it completely wrong it's when a device (stompbox for example) is connected to your chain but does not affect the sound unless it's activated.

and to the real reason for me startin the thread. I've got a number of pedals. Reverb, delay, flanger,phaser,tremolo, noisegate, loop station, distortion modeler, and a wah (and I'll probably get a few more in the future too). They're all BOSS pedals (except the modeler and the wah) and they don't have true bypass. Last week, for the first time ever I rehearsed with ALL the pedals hooked up to the effects chain. And boy did I loose a lot of tone!!!

So my question is. Is there any solution for this? I'm not gonna modify all the pedals so dont even mention it. But is there some kind of bypass switch/unit or a special way to connect the pedals that would remove the "tone-loss"?

And oh. any other questions or topics concerning true bypass can go in theis thread too!!!

I don't have a link, but I saw a "true bypass" rig one time - it takes regular pedals and lets you swtch them in and out usig tru bypass rather than the units own internal bypass.

Actually, such a think isn't technically very hard to build, just a bunch of foot switches and relays ...

I think it´s recommended that distortion and Wah pedals should be used in front of the amp, but not in the effect loop. Delay, Chorus, Flanger, Phaser and such effects should work better in the loop.

Here is a fine article about this.

Brilliant article. Thanks man. even though I knew about the whole "modulation effects in the loop"-thingy it definetely lightened things up. Only thing now, is when I start building my board I'll have too thing about how I'm gonna plug into the amp. Darn.

True bypass refers to how the signal is routed through a pedal that's switched off. True bypass devices route the signal around the pedal's circuitry so it goes as directly as possible from the input to the output.

Pedals that don't do true bypass route the signal through its circuit when the pedal's off but the parts
of the circuit that is supposed to change the signal is turned off.

Soetimes this is an issue, sometimes not. Depends on what you want from your sound. If you ahve a bunch of noisy pedals, all chained together, you're going to have sound issues because as the signal goes through each device it changes a little bit...and that little bit adds up over 10 boxes.

I suppose it's possible to mod pedals to have a true bypass mode, but I wouldn't know how to do that without a lot of research.

What I would do is figure out which ones were the noisiest and then separate them out with some kind of splitter switch. Guitar into the splitter, one lead goes into the noisy pedals, the other into the clean ones. When you're not using the noisy ones, cut them out of your signal chain altogether. Kind of an outboard true bypass. smile.gif That can get a little complex and expensive eventually though.

Tru bypass allows for less signal loss in your chain..You don't need to have a power on in a certain pedal with tru bypass in order for signal to go through it..I have a friend that had done such modification to his pedals , It shouldn't be hard to do (by experienced electronics guy)..

well i personally hate my guitar going through loads of pedals as by the end of the chain so many frequencies have been lost and the pure sound of my guitar has been coloured... some pedals are worse than other for this. For example I stopped using a wah in my chain for this very reason.... especially cry baby, I find it really altered my tone even when it was switched off....

so to remedy this I am going to buy a http://www.voodoolab.com/gcx.htm
all those loops mean that I can have only the pedals I want on when I want them.... and when I dont want them I can de-select them so they are not in my chain at all

great stuff.... better sound, but more expense as always - it never ends!
check out scott hendersons current rig - very interesting.

Also you can get a little preamp to put just after the guitar and you will get the tone. I've heard people done this.

This is actually what I had in my head while I was typing my post out. It would be nice if someone had a box that would isolate all of the effects into their own loop.

Hah.
