I have one church that I play at that uses IEM that I want to get a good Cheap DI box. I have been using just my Genzler 800 head as the DI out to feed the house and it does good but I'm wanting something a little smaller that I could thrown into my gigbag and not worry about it. What is the best options for new or used at $200 or less?
Interesting question. I'm a big fan of Radial gear, so if I were to strictly stick to your price guidelines, the JDI has no equal I'm aware of as far as passive direct boxes go. Especially If you've got everything dialed in from your active bass, the JDI will do the trick in the smallest, simplest package, and offers a very pleasant passive compression that will probably be noticeable, unless Genzler uses an equal quality DI transformer. I'd venture a guess he doesn't, but I love that guy's gear too, so who knows.
But let me also suggest the Radial Firefly, which is a tube DI box that offers a little more practical flexibility as well, in that it has volume controls, a drag control (which may not be of much consequence on your active bass), and IMO the most useful feature, a high pass filter, that allows you to dial out unwanted low rumble and really sing through a mix. The REDDI is also pretty sick, but it only does one thing, albeit very well. It's a great box, I have no intention of selling mine but I have to say it's moved down the bench for a few reasons. I usually want more transparency and flexibility for bass and guitar, so for the last 3 years or so my one go-to box is the Firefly. It's also much smaller and has a handle, the REDDI is a beast, I haven't used the Genzler amp but I would venture a guess the REDDI might actually be physically longer and heavier. I have a tiny recording space so my REDDI only makes a few appearances a year now, the Firefly sits on top of my interface when I'm not using it at a gig.
The Firefly is way out of your price range, but if you ever had designs on getting a fantastic active DI equally good for recording and live use, it might be worth saving up a few more months.
Oh yeah, to be clear, the Firefly and REDDI are both active and require mains power. The simplest solution is the JDI, no plugs, no battery. There are also Radial boxes powered by phantom power, I don't own any as I don't want to rely on the venue having phantom for me. They also cost a lot more.
