    I decided to record and do a side by side comparison of both of my DIs (radial jdi and ampeg svtdi) as well as the built in DI on the ampeg svt450 which has been my go to amp for my last 4 gigs.

    My favorite was the svtdi (warmest sounding) followed by a close second by the radial. The di on the svt450 isn't bad, but it sounded thin to my ears no matter how I set the amps EQ.

    heres a clip (some punk ska) for the TB community and the specs:

    Ibanez Precision strung with rotosound 77 flats. Focusrite saffire 6 interphase. Clip I: Ampeg SVT 450 amp built in DI (slight treble and bass boost), Clip 2: Radial JDI, Clip 3: AMPEG SVTDI tube injection box. No EQ was added to any of the clips, just slight compression (focusrite compressor plugin).

    I will try to get some more DIs to compare in the next couple of weeks maybe.

    I thought the SVTDI sounded the best by far. Seems to have that "it."

    Ahh, a pun...(sorry guys). Love the tone that you're getting on the dazed and confused cover from your cloud, mr. garmenteros! What's the bass and rig used for that song? recording device? I, too love some RAGE; anything special that you're doing to dial that in? Well aware that most is coming from your technique..
    thanks, newbie trying to learn,

    Is that what you record with? I have an opportunity for the svt 450h at $400. Is it worth it? Would it take me through my first gigs in bars/small clubs? Does the ip fix it?

    My zeppelin tribute band's version of dazed and confused was recorded with a 70s ibanez jazz bass with rotosound flats with an ebs valvedrive (tube pre) into a radial jdi (i got the svtdi two weeks ago). Fingerstyle about midway between both pickups. I also had an ampeg b15n that was miced with a shure beta52a mic and we blended the signals, but I think the EBS and radial got the most of it. The interface used for the sessions was a focusrite liquid saffire 56.

    For live gigs with this band I used an acoustic 370 amp into an ampeg heritage 410 with my pedalboard (which has the ebs valvedrive on it).

    For the rage tribute gigs I did I used a modern sounding custom 5 string jazz (graphite neck, bartolinis, 35 scale). I use the ampeg svt450 because the acoustic 370 is vintage voiced. Eventually I plan on getting an ampeg svt heritage. I just try to sound really aggressive but at the same time clear and warm for this gig (the svtdi and ebs valvedrive help lots here). I boost the treble more than I'm used to on the ebs preamp and the amps EQ section because Tim C. has that attack in the high frequencies to me (probably has something to do about running dirty and clean cabs and mixing to FOH). I play almost at the bridge and hit hard and to top it off, have fun with a few pedals. Heres a crappy cellphone video of one of our gigs a month ago.

    I don't record with the svt450. Its an OK head and would definitely get you through your first gigs and then some. 400USD sounds about fair for it, you could probably find one maybe 50 bucks cheaper but if its in good condition 400 is on the point. I just wanted to record some clips from the amps DI at home so other bass playing brothers could compare to some other standard and common DIs. I do medium clubs with and without PA support with the svt450 (maximum capacity anywhere from 100 people to 500 typically) and it gets the job done. By itself the svt450 sounds a bit sterile so I help it with the ebs preamp and svtdi (both tube driven).

    In the studio I use my EBS valvedrive and my ampeg b15n miced. I got the svtdi a couple of weeks ago and will be using that now as well.

    That's what I call a fellow TBer laying out the data, people! Thanks for all the info this greenhorn can handle for one night. I'll be GASSING on the specs of the gear, particularly the pre amps, way past my bedtime. Thank you, tb brother from way! down south-- just wish Louisiana got any kind of ocean breeze... gotta get a sail boat.

    Nice comparison (and playing) garmenteros. I often go straight DI (Aguilar Tone Hammer which I suppose is not straight DI) with no mic'd amp in the studio, so I found this to be a very interesting comparison.
    I liked the SVTDI.

    My PF350 is pretty easy to haul to the studio but I'd still like to see Ampeg re-introduce that SVTDI as a pedal size tube DI with some basic EQ. I'd buy that in a heartbeat.

    Checked the SVTDI manual in the Ampeg discontinued products section. It's a cool piece of gear. Ampeg's version of the REDDI maybe?

    Kinda sorta, but there's no output transformer on the SVTDI.

    Ah, good point JimmyM. Seems that transformer would make the difference in the REDDI's output being more "tube amp like". I do like the design of that SVTDI though. Wish they still made it.

    Radial has a new tube DI called the Firefly. This thing looks pretty sweet on paper, I've never played one.

    It does. I was between that, a REDDI, and the ampeg SVTDI and ended up with the SVTDI. Heres a pic of it on my rig last saturday.

    Did Ampeg ever really gave them much of a push? Saw several in use by touring guys on arena shows I worked a few years ago but never saw one in a store that I can recall.

    BTW, I must correct myself here, lest Jerrold give me the business. The SVT-DI does have a Jensen output transformer, which is pretty cool but nothing like a big 4 lb. hunk of iron what's in the REDDI. But while I have no plans to do any more DI shopping unless it's a backup REDDI at some point, the Khan/SVT-DI does seem to be one of the better DI executions out there. The tube actually does something ;)

    Jeff, as far as a push, I do remember seeing a couple BP ads, I think. But while their pres and this DI were generally very well-liked, they just didn't sell in high enough numbers to keep making, so whatever push it had ended after sales figures came back.

    Now I have to buy DI's that cost more than amp heads to get the sound that I want out of an amp head/cab? REDDI at $700+? I thought it was all in the fingers!
