Double Bass Red Eye Preamp

Is the TRS Yamahiko? I found the impedance in general to be too low on the fire-eye to be useable with the Yamahiko. The gain pots don't work like a mix knob. It's the most expensive option but the Grace Designs Felix is amazing with the trs Yamahiko. I use the phase switch on the Felix. Without it, it sounds choked. I don't remember there being a phase switch on the Fire-Eye.

Interesting comment on the Fire-Eye impedance being too low for the Yamahiko. I added my name to the list for the trial, sounds like it might be worthwhile to wait my turn before spending any money on one.

I've got a Grace Felix and I really like it, but it's pretty big and I've got it mounted in my gig box. To be honest, I've probably got too much stuff. It's a problem, I admit it and accept that. Some people buy lots of basses, I buy preamps and cabs.

Some gigs I play are pretty tight and I want something small that I can pair with my MAS 16 powered cab. I haven't finished making my TRS Yamahiko cable yet. I've got the split cable made, but I'm waiting on the TRS female plug to arrive.

I'm about 90% in love with the Yamahiko with both a ToneDexter and the Felix as well. I'm thinking if I could adjust the phase I'd probably be 100% in love with it through the Felix. For comparison, I was about 65% in love with my Lifeline.

Thanks for the feedback!

With the TRS cable the Felix is pretty slick. The phase switch on the Felix does make a world of difference for me! I have the Felix on top of a GSS sumo power amp. It's not the smallest solution but it's pretty light and easy to move around. I'm looking forward to hearing your experience with the Fire-Eye; who knows it may be perfect for you and your bass. Only one way to tell...

no phase on the Redeye. I tried running both Yamahikos to the redeye but didn't find that it was better then the Y bridged. The Yamahikos TRS'd into the Grace is a great sound with lots of variation and super simple. I did a trio gig the other night with the Redeye into a tube pre and then the MAS16 and people in the audience thought it was the best bass sound they ever heard and that was with my Contrabassetto. Clear and rich and distinct. I found myself turning the treble knobs on the Redeye way up, which was interesting. I guess I also had a Fdeck in there....I always have the Fdeck on the 16, without it it is possible to bonk the speaker.
 
Red-Eye received safe and sound (thanks Fire-Eye and thanks @crd !) First use was at Denver's Dazzle jazz club, pic attached. Backline is a Henriksen combo (with a 12" I think) and signal chain: Realist Lifeline -> Red-Eye -> fdeck HPF v2 -> Henriksen, with the Red-Eye also feeding the house (so yes, pre-fdeck). I use LaBella 7710N strings as I find them to have a very precise and controlled low end when amplified and I like the complex mid/high texture in the mix.

First reaction... wow. I've played this room quite a few times for comparison. It's not a terrible room acoustically and the sound folks are quite capable. There's always a lot of variability in the resonance of different notes of course, and this is a loud big band so feedback can be an issue. It's also a big Upton Brescian so lots of lows to manage.

The moral of the story from the night was quite similar to some of the comments from other folks on this thread. The way much of the register "sat" in the mix was much improved from my last recollection - well defined, clean, articulate, but still very thick and round, with a lot of "shape" to the note rather than being 2-dimensional. That was less true down low on the E string but I'd attribute that to the single 12 on a stand fighting a loud band, as well as the hpf which I utilize (post-DI in this case) to remove the deep mud on stage. I used the treble control at 50% and used the A/B for a mute button, which was a nice feature.

The other thing that kept hitting me about the red-eye is that it seems to smooth out those piezo thumps in a very musical way, getting to more of an "acoustic attack" rather than an "artificial attack". I mean those times when you dig in a bit and if you were unamplified it would be fine, but with the pickup it's harsh. That's probably improvements I should make in my technique, but each note sounded increasingly musical and sweet to my ears.

I'm no @Chris Fitzgerald so there weren't any people coming up to me after the show telling me I sounded good.... although a woman in leather pants did come up and say, "I know you're married but I'm crushing on you and your bass on stage", (so I really can't complain)... but I thought it was the best bass tone I've achieved in that venue. More importantly, the band seemed to respond differently, as if the pulse had more authority and clarity.

That's really all so far as I haven't been able to use it in a more intimate setting. Will do that in rehearsal tomorrow. Since I'm the basstaster(TM) I'm planning on doing some recordings to share, in various configurations (with Noble, fdeck, EA Doubler), mainly to prove to myself that the difference is not psychoacoustic and then exactly what the difference is. Feel free to ask questions in the meantime and I'll be back with more observations soon. Thanks for reading!

I’m no @vanselus, so the people coming up to tell me the bass sounded great are not often women in leather pants. Make of that what you will. :D

But please do tell me more about that Henriksen combo with the 12. I’ve always wondered about those, but never encountered one in the wild. I have a virtuoso guitar colleague who plays Henriksen guitar amps, and they sound ridiculously good. But then he’s also ridiculously good, so it’s hard to tell what’s what.
 
Interesting! My guitar colleague has long used Polytone amps, and it seems like the Henriksen amps are upgrades on those old classics. Back when I played guitar, I always got a great thick clean sound through an old Mini-Brute 12. I still have that amp, but it has more coloration for bass than like.
 
Polytone, my my, well let's just not talk about their pickups.:roflmao: Yikes. The amps were fine, unfortunately
for some reason it's very difficult to repair them now, from what I can gather. A clarinet friend of mine
has a Henriksen. It sounds pretty nice.
I got the schematics and repair and adjusting info for the Polytone MiniBrutes. I have a MiniBrute 2 which is the 12” with the spiral reverb. The MiniBrute one is the 12” without the reverb and the 3 and 4 are the 15”, the 4 with reverb.
Unfortunately there is an IC inside that is no longer available and can be damaged when a potentiometer is set wrong (or looses contact due to corrosion).
My one has an unpleasant buzz that might be a result of age if components or a badly adjusted pot. But in the last ten years I didn’t find the time to adjust/repair it, since I’m anxious to damage it beyond repair. Doing things well and controlled needs a lot of time to avoid a total damage.

Here... we... go... thoughts tomorrow, audio now. The 28 tracks are in Soundcloud and if you click through, there's a more elaborate description of the signal path for each including knob setting details and the like. Enjoy! Also, here's the link right to the playlist: Basstasters: Red-Eye Tests


Wow the Noble sounds really great especially with HPF!
 
I played a gig last night using the Ehrlund into the original RedEye. The difference was even more obvious than with the other pickups I have tried. I played more arco than I have on gigs like this for a while and I didn't have to make any adjustments to have a sound I liked for both arco and pizz- one less thing to have to mess with, which is something I really appreciate.

I seem to have derailed my quest for simplicity somewhat, but the RedEye is still involved. For louder gigs with drums and louder guitars,etc. I've decided on an old Clevinger pickup(seriously) through the RedEye straight into a TC electronics amp and old Acme cab. For quieter stuff the Ehrlund into the RedEye into a Fishman pre(the EAP needs a boost) into a WW into an Upshot does the job pretty well with a minimum of extras. My takeaway from all of this experimentation with gear, which I really don't like doing if I don't have to, is that the RedEye is really a functional and adaptable piece of equipment for me. It makes some really old gear have new life.
