[h=3]Do Visual Sound pedals have "true-bypass";?[/h] No, but for some very sound reasons. And they have something which may be better: Pure Bypass. The switches required for "true-bypass" are much less reliable in the long run, typically rated at around 5000 stomps, but often lasting less than that. They also cause audible switch pop through your amp.
The V2 Series pedals have a proprietary switching system rated at 10,000,000 stomps and are virtually silent. The V2 switches actually cost us a lot more than 3PDT "true-bypass" switches, but they're well worth it.
Secondly, the buffering system in the pedals was taken from our Pure Tone pedal. This pedal was built originally for guitarist Neil Zaza who needed something to clean up his bypass tone for all the pedals he used (VOX wah included). Pure Tone, when placed first in the chain, made it sound like you were plugged straight into the amp even when going through notorious tone killer pedals. We ended up selling about 200 of these to very happy tone conscious guitar players before we put it into Jekyll & Hyde as an added feature.
So, if J&H or Rt. 66 is first in your chain, it will buffer everything that follows it as well as itself. Even if it's in the middle of the chain, it will still work to some extent.
Thirdly, the Pure Tone buffer also keeps the Hyde circuit (in Jekyll & Hyde) stable. In the early stages of design, I noticed that the Hyde circuit was prone to occillation and feedback until I put the Pure Tone circuit before it. Somehow, it left all the good characteristics in tact and eliminated the ugliness.
