That's an amazing price for this pedal.
the scratchy gain control is part of the circuit design (it's based on the zvex SHO). it's a variable bias on the gain stage. on the zvex pedal it says "crackle ok" on that pot.Just bought a JPTR Jive, interesting, find the gain pot being (quite) scratchy though. Is it something related to the circuit design, or is it related to my pedal ?
Interesting, so its a mosfet stage? I've been meaning to open it up.the scratchy gain control is part of the circuit design (it's based on the zvex SHO). it's a variable bias on the gain stage. on the zvex pedal it says "crackle ok" on that pot.

yep it's a BS170 mosfet transistor.Interesting, so its a mosfet stage? I've been meaning to open it up.
It feels like a dumb question, but is it 'intended' to drive and clip itself in that case? I had been avoiding it because I weirdly assumed it was an op amp thing, and I like it fat and clean anyway, and the diode options sound nice.. perhaps I need to re explore just driving it hard again.

I had problems with noise with a cheaper power supply (or maybe with the power filter I had it plugged into) depending on a few things it was anywhere from a buzz/hiss to a whistle/whineI just recently got mine and absolutely love the warmth of this pedal sounds amazing in front of my ampeg opto comp. How ever I am have trouble with a feedback/hiss even with gain at lowest setting. Has anyone else had the same problem or is it something will just have to put up with?
fyi the cheap supply I had problems with was the OEM Source audio wall wart, so it's not like it was a $.07 Chinese Amazon special. No problems since then on my Voodoo or even my regular old 1spot
I'm hesitant to offer this with johnk floating around here, but a single transistor topology will be more susceptible to bad power supplies compared to op amps.. similar to why fdeck switched to Op amps for the HPF pre that could be adapter-powered .. Common mode noise rejection becomes something to battle a bit
No problem with my OneSpot. If I run off the 9v output of my rechargeable battery block, I get unpleasant noises; it's fine off the 12v output. So yeah, it may be slightly finicky with anything less than a robust 9v.
I had a carman 9v wall supply adapter that was really bad and the guy at local music store recommended a onespot 9v wall supply, it's definitely not as bad as the cheaper one I had but still very noticeable especially with abit of gain and tone knobs wide open.
I've got one coming. It's no different than having 2 separate Jives. I'm pretty sure you need a small patch cord between the 2 channels if you want to use them together, but I think typical use is using it at 2 different points in your chain, or in stereo. I already have a normal size one, I ordered this one for possible stereo use.Anybody has an experience with double jive? How does it work. What I don't get is four inputs/outputs....

Just one power inputI see. So in order to use as a two channel overdrive (taht's what I plan), I would need to connect it with a short cable...
Does it feature one power input or two?

Other purchases came up (I'm looking at you, Origin DCX), so I cancelled the double Jive. I already own a normal Jive, so no big loss. I only cancelled a couple weeks ago though, so not sure if I would have it yet anyways.Has this arrived Derek?? How is it? I too own a Jive and am looking at the Jive evil, possibly ordering today. I am interested in using them both on with very low gain as a more/bigger tape effect on my sound.
