Ibanez Jet Drive

Just saw this in a Guitar Center mailer I got in the mail a few days ago. Anyone know if it's a new circuit or not? It looks a lot like a repackaged Turbo Tube Screamer looking at the exterior of the thing. Just curious if anyone knows anything about it...

It doesn't sound too bad. I wonder what it looks like circuitwise.

SD-9 Sonic distortion with mids control?

It's a pretty pointless pedal if you ask me. Is that guy resting his guitar on his beer gut??

Hmm... maybe.

I think it could be useful in the right hands. I'm just wondering if it's a new design or a tweak on an existing one.

Gut shot:

And it's probably ST-9.

Hmm... yeah maybe it's a re-labeled/slightly tweaked(?) ST-9.

That Man drunk a lot of beer... <hic>

Another decent Demo by the Tone King. Like the sound of that one...

I bought one today. Gonna mess around with it and see how it works for me.

Cool! Very interested in your report.

Paul Marossy · November 14, 2011, 09:59:21 AM

I used it last night, it sounds pretty good I think. I'm trying to think of what to compare it to, but I can't quite put a finger on it.

One curious thing about this pedal is that it makes a little bit of a popping noise when I switch it on/off. My TS-9 and TS808 reissue don't do that. I thought only mechanically switched true bypass pedals had that problem...

> I thought only mechanically switched true bypass pedals had that problem...

Any switch can do that.

Usually the electronic switch designer has to "think" and use a lot of little parts, so pop-control is designed-in.

Leaky (overly cheap) caps can foil the designers' intent.

Paul Marossy · November 28, 2011, 01:02:44 PM

I'm wondering if mine is defective. I'm sure that this pedal has the same switching scheme as every other Ibanez pedal does. My other Ibanez pedals don't do this. Maybe I need to take it back and get a new one...

The ST9 and STL use a dual pot for the mid control. This one does'n't seem to utilize a dual pot.

Looking at your pic suggests the whole bypass flipflop circuit is absent. Might be they use the same 4pdt miniature switch seen in the current Maxon niners. Check what's underneath the switch and you'll know.

I have a Maxon AD-9 Pro delay which I believe uses a miniature 4dpdt for true bypass. Nice delay but it pops when I turn it on. It also cuts the signal momentarily when turning on or off. Really annoying. I wish they had stuck with buffered bypass.

It's not my picture, but that is an interesting point. Could be the case.

Huh, that's kind of lame. I'm not going to take my Jet Driver apart to find out, but it sounds like maybe that is what they are doing these days. So I guess I'm wrong about it using an FET flip-flop for circuit bypass. Gee, why fix it if it ain't broke? See this is a perfect example of how true bypass mania is not always a positive thing.

According to this article, the Jet Driver is a true bypass pedal: http://www.premierguitar.com/Magazine/Issue/2011/Aug/Ibanez_JD9_Jet_Driver_Pedal_Review.aspx
They say that it's a standard TS circuit with a mid-control.

They have some work to do. 98% of my high gain DIY pedals are true bypass and they don't pop when switching on/off..

Paul Marossy · November 29, 2011, 10:10:40 AM

Just for the record, I like the pedal. It works pretty well with my '95 Parker Fly Deluxe and my self-modded '98 Fender 2x12 Hot Rod DeVille with Celestion speakers in it.

I'm sure it's not for everyone, but it works for me.
