Ampeg B-15 and DI Boxes and "Ext Amp" and etc.

I posted this in the Blueline Club thread already, but since this was a specific thread to the topic, I'll repost it here:

OK, just heard most of your clips. Honestly, it was really tough to find any bad sounds at all. All of those sounds are quite heavy and usable. What surprised me the most is how well the pre-out of the SVT and V4B worked. I guess I shouldn't be surprised because I got similar results with the DI's in my Heritage SVT and new V4B, although I did end up favoring the REDDI ever so slightly. Mostly it's because my amp settings are never nooned, but also because the OT in the REDDI gives it a tiny bit more bang zoom than just the pres in the SVT and V4B, although, as your test points out, it does hang extremely well with the REDDI. But that REDDI has something to the sound that just draws me in, so for me, that was my #1 choice with all basses.

BTW, your playing kicks total ass!
 
Sorry - link is now working (edited previous post). The playing was done by 3 top notch Dutch bassists: Aram Kersbergen ('55 P / rounds), Manuel Hugas ('63 P / flats), and Kobus Groen ('73 J / rounds).

Ok... bringing this one back because I was curious too.

I've usually run a similar set up with two class d heads and cabs anyway.

Split the signal. I usually use a TU-2, this time I tried my VT-bass Deluxe using the output and the parallel out. I send the parallel out to the Ampeg and the effected output to the Epifani because that's much easier to control and prevent it going way overdriven.

No detectable problems with phase and it gets super loud. The B15S is on the Guitar setting in channel 1 with the lows and treble about 10-11:00. The Epi is flat with a bump on the lows.

I wanted to back away from it to see how it throws. Very nice. I'm not sure if I'll get a spot on the PA, and I don't think I'll need one.

I figure is much less risk to the transformer than using the ext amp or ext cab outs on the B15.

The speaker out jack on a B15 cannot be used to feed a speaker level DI. Whatever is plugged into that jack is in series with the internal driver and a switch on the jack changes the tap on the OPT from 8Ω to 16Ω.
On the bright side, 1/4" adapter cables for those 4-pin XLRs are readily available from Fliptops, so you can do speaker level DI from the main speaker out.
