REDDI Tube DI Mega-thread-III

Preparing for studio work. Passive jazz into reddi and rbass enhancement. Really warm and big sound.

Forgot to comment on the JM3001. Yeah, it's pro grade in every way. Basically, the bottom end is HUGE. Not in a bloated way but, that it actually seems to extend all the way down to hell without sounding muddy. It sounds subsonic without destroying your cab. It is super fast and clean but not in a clinical, dry way. My big test is when I tap a plucking finger down the length of a string to see how many harmonics come out. They all come out with this preamp. The mids and highs are "natrual". Not hyped or degraded in anyway but, just how they really are. The eq is powerful and effective and the low and hi pass filters are very useful. The unit is rather heavy for a preamp which, is what I've noticed from other uber quality gear. Im actually going to sell the unit because it is in 100% mint condition and Im too squeemish to bring it out to a live gig. I did the same thing with an Amek 9098 that I loved but, it was nearly drowned by a sticky pink drink one night so, I sold it too.

So you don't worry about your gear on gigs, maybe you should replace it with a Behringer ;)
 
Even in this cesspit of incorrigible gear whores constantly buying and selling I'm still always kinda surprised when I see a REDDI up for sale.

I've always thought that Talkbass could use a tagline that describes what it is about to the uninitiated.

"A cesspit of incorrigible gear whores." is the finest, most perfect description of this wonderful site that I've ever read.
 
Thank God that ive been busy this summer. But I forgot all about this KGB unit.. Did a small demo for local radio thing today in my home studio and decided to try this.. WOW.. sounds great.. it s a High Gain DI. Preamp... Im taking it to a session next week and let the Guitar player try it out since they always cut him a mic on an amp and a DI signal too for later processing see how this goes.

Here's another "guess the REDDI" post. I think the REDDI is a terrific DI. There are other excellent DIs, too, and each can have its place depending on recording production goals, output by particular instruments, strings, pickups, etc. I've designed this to be a "blind" test with a REDDI all-tube active DI, [Invalid or Expired Link Removed] class-A active direct box, and a [Invalid or Expired Link Removed] passive direct box. I will post what's what in a few weeks after you get a chance to audit the results. Best way to audit is to download each group of three randomly labeled files and drop them into a DAW, allowing you to switch back and forth for instant DI comparisons of the identical test. You can also play the files directly below. WAV files are hosted in my Dropbox account.

DIs & SIGNAL CHAIN

The bass was plugged directly into a REDDI ---> REDDI out jack into a Radial JDV ---> JDV out jack into a Radial JDI. This configuration enabled a simultaneous 3-channel recording through all 3 DIs.

XLRs from the 3 DIs went into a Zoom H6 solid state recorder @ 48Kbps/16 bit WAV. The recording inputs were set to -6dB for all 3 channels. Output from Presonus Studio One into 44Kbps/16 bit WAV format with no EQ or compression applied. Photo of the testbed:

THE EXERCISE

I played finger-style chordal scales (modes) starting at the bottom of the neck to the top using the open A string as base, then shifted to the E string and proceeded back to the bottom of the neck / open E string. Going up, I played legatto notes at different tempos. Going down, I played stacatto notes in quarter, triplet and eight-notes. The result provides different note envelope patterns at all points of the fretboard. The exercise took about 20 minutes. I repeated it twice: once for each instrument.

INSTRUMENTS

FrankenFender P-Bass -- 20-frets on a MIA neck, strung with brand new groundwounds (loosened up with two hours of play prior to the test), passive Lindy Fralin pickups & Babicz bridge & Hipshot Ultralight tuners on a MIM body, volume and tone knobs on full. Played with fingers over the pickups. WAV files for the three randomly labeled DIs are:

Rob Allen Deep 4 fretless -- 22-frets, black nylon tapewounds, active piezo pickup, EQ settings flat. Didn't quite make it all the way to the top of the neck as the two extra fret regions make the fretboard wider (and harder to play with my short reach). Played with fingers about an inch or so beyond end of fretboard. WAV files for the three randomly labeled DIs are:
