I understand true bypass, and I get the idea of buffers, but my EVH Phase 90 is apparently 'hard bypassed'. What is that? I noticed that I still get sound through the pedal when it is unplugged from the power adaptor. I thought that only happened in true bypass? Also, the back of the curcuit board seems to have six solder points throught the switch. Doesn't six points suggest a DPDT (or whatever) switch? Aren't they the ones usually used for true bypass? I'm confused.

sooty,
New name, same old effect. Hard, true, whatever, it's still completely removing the circuit from the signal path.
BTW, the removal of power is not an indicator of true bypass. The whole reason for true bypass is that the effect's circuitry is removed from the signal path, both at the input and at the output. But if you remove only one end, leaving the other connected, you'd still have a bypass - the effect is not heard, right? Even if you remove power, the signal still flows without hindrance...... er... wait.... no, that's not quite true. In a simple bypass, the fact that one end or the other of the effect circuit remains connected at all times means that there is a load on the signal path, and that will affect the tone - usually in a negative way. A true bypass, having disconnected both ends of the effect circuit, allows all the tone from the pups to go through unmolested.

Well maybe 'hard bypass' is more like that one end connected thing - because these pedals have a reputation for being tone suckers, although I really don't notice it. I'm pretty sure it's not supposed to be true bypass, becuase they don't say it is (they say hard bypass), and tru bypass is all the rage with pedals these days.

sooty, I suppose a "hard" bypass could be the theory of a wire running from the input jack to the output jack, all the while one of the circuit ends is still hooked to that wire (either end, it won't make any difference). When the power is off, and the switch is in 'hard bypass', then the signal will still be heard..... robbed of tone as it is.  That's in contrast to some pedals that add a buffer stage, and the straight pickup signal runs through that buffer all the time. No power equals no signal at all. In my book, that's not any kind of bypass, that's merely turning down the effect until all that's heard is the straight pickup signal. Or what should be the straight signal, but as you've found, the tone is usually sucked right out of it.  HTH sumgai |

I don't understand why anyone would want to make this kind of 'hard bybass' - if you're not going to buffer it, why not true bypass it? Surely the best options are either True Bypass or buffered.

the pups to go through unmolested. Explains my reference for true bypass. I never liked Uncle Badtouch. |

sooty, Simple: expense. It costs more money to buy a DPDT switch than to buy a SPDT one. At retail, in quantities of one each, you and I don't see that it should make a difference to the company, given the desirable benefits. But to the company, it could mean the difference between pricing your product competively, or pricing it out of reach of your intended market. Doint the latter is normally called "a bad business decision".  And that's not to mention the time needed for a person to solder the additional wiring to the "extra" switch terminals. Man, those labor costs will kill you everytime!  Ah, the munificence of a free market!  HTH sumgai |
