Tech 21 Club

I swear by Tech21 pedals, I use them all of the time but obviously not all at the same time...lol!

OK, I just finished dialing in my new to me, old BDDI to my liking, and did a little recording using one of the last bass-less tracks I had on hand.

VT Control

While the differences are fairly obvious, I was surprised by a few things - first off, it seems I liked the BDDI with a little less drive, at least in a way. Second, I was surprised by some of their similarities, but I guess given that I dialed the BDDI in by ear, my personal tastes, or at least what I'm used to came into play.

Just for fun after I was done, I hooked up each preamp for some frequency analysis, and this is what I found. Take this with a grain of salt, as it doesn't tell the whole story of course, but the curves are fairly similar, aside from that mid-notch that the BDDI is so famous for. :D

I wasn't expecting for the BDDI to have an earlier low-end roll off, but I think you can hear it in the clips above.

Two more recordings, in the mix this time. I'm done recording for the night, but I wonder if I should make a VT version with less drive to make it a bit more of an even playing field...

I do still like both, but perhaps the novelty of the BDDI is winning to my ears for this mix, even though the VT certainly is a bit more present in the mix, thanks at least in part to not having that mid notch of course.

The BDDI was a favorite of mine for literally decades! First got it back in the early 90's. The mid notch was usually a good thing, perhaps because I prefer mid-forward basses and amp rigs, but if it was too much then I would simply dial in dry signal via Blend. The Presence knob delivered a nice aggressive edge for rock.

I'm kind of sad that I no longer own a BDDI, but my other Tech 21 pedals stay in rotation: DP-3X, SH-1, Oxford, and Leeds. What can I say, my ears are fickle... can't stick with just one.

A better upgrade is the Para Driver with fully sweepable Mids. The Bass Driver is a great pedal, but to have the option of sweepable Mids makes the Para Driver a more useable pedal in my opinion.

I'm a big fan of the paradriver. I do like being able to sweep the mids. Ivd had mine for 3 years or so as my main preamp on my board and really like it.
 
I'm still using the BDDI v.1 as a preamp into the power amp of my combos. Sounds just fine to these tin ears. Although, I do have one problem with it. Since I run the Presence at zero, and have for years, I tried turning it up and the sound from the BDDI cuts off right about 12:00 I figured the pot got all gritchy inside, but moving it a bunch didn't seem to clear it up.

It's most likely the pot has gone bad. If you want to have us a repair it, please contact our support department.
 
Could someone please tell me about this steel plate on the back of my programmable BDDI. It say "quick release" in script and I'm wondering if it is stock or an aftermarket add on. I bought it used and the seller did not mention it.

it's from Temple Audio. They make pedal Boards and these are used to attach to the boards.

Hi folks, wondering if anyone has any insight on this... I've been a BDDI user for years and love it. I recently picked up a YYZ off craigslist out of curiosity. I got it home and no output except for static-y growling coming out of the amp. I used a cable tester through the YYZ and a known-good pedal and see the attached (same cables, die-five shape is good pedal, die-six shape is what we see from the YYZ). I've got an email in to SansAmp to see what they think, obviously not a warranty fix but maybe they can resurrect it if it isn't user-fixable. Also don't buy pedals off craigslist unless you see a test :)

It think it's solved... some jack vacuuming/DeoxIT D5, and giving it a beefier DC adapter looks to have resolved things. Sorry about the reversed in/out shown in the tester... it's a continuity test but for cleanliness should have done better :)
