Double Bass Revolution SOLO Pickup Reviews

I describe all the details of installation to the email i sent to Eroy:

<<<< Dear Eroy,
I want to describe with details the procedure of installation that i did. I received the RS the first days of May, one afternoon, and the same night i had a gig to go and play. I was so impatient to try it and also been in a hurry, and i sanded, not all the horizontal surface of the wood, but i started sanding from the upper edge going to the center, in a way that finally only the half about pickup (till the "R") fitted to the E gap of the bridge.The other rest half pickup was not inserted into the gap. I tested the sound, it was excellent, and OK relative to the output level.
I played to several gigs (7-9) with this configuration, believing that it works good like that and intending to sand all the woody surface some day. I was always removing the pickup after the end of the gigs.
I have to mention here that i used to play at low volumes, almost acoustically, at a coffee-shop. At the last gig that i remember to have the normal output level, i played two or three pieces with a very noisy drummer and i increased my volume at a high level. I think that was it. From then i 'm experiencing an extremely low output level. I suspect that maybe the piezo element is been cracked. Later, i sanded all the surface and fitted it, but there was no change at the
output sign.
I beleive that i must send it to your service department, you will examine it and then decide if it needs a repair or reconditioning.
Waiting for your advice,
With best Regards, Panos.>>>>

...And i received his answer:

<<<<Gary and I have talked and we will agree to send you a replacement pickup at no charge after we receive the faulty pickup from you. I will ship the same day I receive.

I feel that your installation method may have caused stress on the element that it would not have normally incurred with the proper installation procedure. I urge you to carefully follow the installation instructions and
procedure with your replacement Revolution.....>>>>

I couldn't realise from the begining that my installation procedure was faulty, because the result was a very good sound, that's why i spoke about mystery. Now i feel that i didn't care as i should about the sensivity of the piezo element. I ought to thank Eroy and Gary Upton for their decision to replace it!

Conclusion:
To the wonderful sound of RS, you can add a great service!
 
actually, this is something we have been debating...but in the opposite manner you are thinking of. We would actually preffer to have people keep it in place and not remove at all, or at least not too often.

Honestly...after placing about 500 or so pickups this year, the ammount of "problems" we have encountered are extremely low, maybe less than 3% overall...but I think it is our anal-retentive perfectionist attitude that makes us want 100%. The problems we find with it though are from people pulling on the wires to remove the rca plug from the connector...sometimes this causes the solder joint to fail in the rca tip. As far as the actuall element being a problem though...that has not been an issue. We got that part pretty bullet proof...our tests show the wires snap before they can pull out of the wood! I think this issue with Panos was a fluke due to a rouge install. I will be curious to get his back and test and disect it.

The RCA to 1/4 connector is a) expensive and b) hard to find. We have been debating getting rid of it and just having a hard wired 1/4 connector (like almost every other pickup on the market). This would solve some supply issues while making it less convienent for bassists to remove the pickup. I was actually going to write to Paul and see if he (and the mods) thought it OK to post an opinion poll about this possible design change. If everyone loves it, and so few have problems because of it, we would hate to kill it because of so few.

This is the same unit that Fishman uses with the FC pickup, no? They have to because of the adjuster wheel aspect. Without that, I can't imagine why you'd want to take a pickup off all the time, especially if it adds wear and tear to the wires.

If Paul's cool with it, I'm on board.

I had been mentally debating this since I've had mine so when I saw the post with that question I thought OK, now is the time to get the scoop. Thanks for the official word...

By the way, thanks for providing such a great pickup... I have had mine for a few months and I can honestly tell you it has revitalized my playing. Gone are the worries about what my amplified tone will sound like tonight or whether I will have feedback beyond control without getting to the necessary sound levels. The RS has worked in every room it's been in and sounds great consistently. Now, I focus on how my hands affect tone and not on how the pickup does.

It might be that my previous set up was just that crappy, but this piece of gear has had a greater impact on my playing than anything other piece I've ever purchased. Thanks for that!

I can add here that i choosed to firm the 1/4 connector on the bass using the traditional way with velcro strip, because i considered that the RCA plugs loose their tightness after a long time of usage. It seemed in that way more easy and practical to me, or just a matter of preferance..

My semi-professional opinion: pull the trigger on it and kill that sucka! As you know, I am already on my second one, plus I hate adapters in general. They're always the first thing to go. I'm not crazy about the 1/4" jacks either, but at least there's only one connection that can go ka-flooey (sorry for the overly technical talk) instead of two. I'd replace it myself if I could solder worth a crap.
 
I stuck the whole rca/1/4inch jack assembly into a piece of black tubing that is about 3/4's of an inch longer than the width of the string afterlengths. Then I secure it with a HEAVYDUTY elastic(black). It works great and is totally removable. Added bonus-acts as a mute. I only have the pickup in the bridge when I need to amplify it.

PLEASE KEEP THE ADAPTER! It is one of the charms and classy aspects of the RS. It allows one to tightly affix the quarter-inch jack while still being able to easily remove and/or replace the RS.

I agree that the RS should not be removed frequently. There is no inherent problem with RCA plugs and jacks. The are among the most robust connectors in use for audio.

Paul

Have you tried it on the G string side yet?
No, but I will. I promised Eric and Gary i'd do that. I'm assuming you're talking about my Bohmann fiver?
When you get old, like me, you get paranoid about changing any thing...i've been so happy with my sound for so many years, i'm just afraid to touch anything.
 
Update! I received yesterday a new RS, as a replacement to my previous which had a low output signal problem.
I installed it this time very very carefully, following the installation instructions. Many thanks to Eroy for his service.

I had read in another thread that Andrian Cho is getting very good results from his Vector pickup with using the gigpro preamp. So, i decided to order and try one, it costed me $97 from shorelinemusic.com
..Well, it is a little magic box, with a pure class A circuitry, 10MOhm input, bass, treble, notch filter (!), polarity inversion etc..

I tested with the RS and i couldn't believe to my ears! (i use the Focus as an amplifier). It made a very big difference. Fat basses, sweet sound...The most important of all is that the piezo thonk effect at the mid range disappeared! In the past, i was cutting the mid range all the way down (8 or 9 o'clock) whatever was the pickup. Now i tried it at 3 o'clock maximum and the result was a very pleasent sound. It did well the trick for me.
Maybe it is the class A architecture that gives that result. I don't know, but if it is so, i wonder why many other manufacturers don't build the preamp section of amps like that.
 
Like panos did, I too recently tried my Revolution SOLO with the L.R. Baggs Gigpro preamp. I still really dig the SOLO, but my inital impressions of the Gigpro were positive in some ways, and not so hot in others.

I can definitely understand pano's comments about the Gigpro helping to reduce the piezo thonk effect. In my opinion, this effect isn't quite as pronounced with the RS as it is with some other pickups, but to a small degree it's still present. And the Gigpro did seem to curb or even eliminate it. I noticed this in particular when I ran it through an AI Series I Contra.

The Gigpro also pleasantly got rid of that somewhat subtle "boxiness" that I have always found present in the Contra (perhaps it comes mostly from their 5" driver?). Finally, I found something that gets rid of that slight styrofoam like flavor in the Contra's mids!

However, the Gigpro fattened up the sound so much that I found it unusable with the Contra. To my ears the Contra can get kinda blurry sometimes, especially in the upper register. The Gigpro just turned this blurriness into a dense fog, even with the high pass filter set to about 10:30 or 11:00. With the Contra in its traditional down-firing position, it was pretty muddy, and I much preferred the sound of the SOLO pickup straight into the Contra, without the Gigpro.

Then I tried using the SOLO and Gigpro through my EA Wizzy combo. Again, I was kinda underwhelmed. The Gigpro took away the natural sounding edge that the Wizzy has ... And I didn't care for that too much. I think that edge is one of the things that really allows the Wizzy to project in a dense live situation. And ever since my ears have become accustomed to it, I miss it when it's not there! Running the Gigpro into a DTAR Solstice and then into the Wizzy was also lackluster to my ears, for the same basic reasons.

The highlight of the SOLO + Gigpro experiment was when I flipped the Contra on its side (10" front facing, 5" pointing up at the ceiling). I don't know yet if it's usable in a live setting, but good gracious ... I was very surprised how deep and natural it sounded. With this setup, the Gigpro did exactly what I bought it for - namely, eliminate the super low end freqs with the high pass filter. This really opened up the sound without taking away any of the meat in the lows and low-mids (which is of course what many of you said would happen - Thanks!). I hope this will work for me in some settings w/ low to modest volumes ... we'll see.

FWIW ...
