Some interesting facts about the Progression Tube Preamp
Posted in Amplification, Uncategorized on October 21st, 2008 by Dieter / 3 Comments »The introduction of the Progression naturally created a big buzz among the acoustic guitar players, especially the ones who are searching for very best sound.
Today I would like to post some additional info based upon discussions with players by phone and email.
First, what’s written about it on our website and in the Progression’s manual is really true and not just marketing blurb!
Let me go into detail here:
This tube preamp was specifically designed to compliment the Pure pickups.
I have always felt that the Pure pickups sound very true and natural, but if their sound is missing something compared to a really great mic, I think it is that their high-end response could be boosted.
To achieve this, we took advantage of one of the tubes’ biggest strengths, their natural and beautiful treble response (compared to solid state technology which tends to sound somewhat synthetic when trebles are boosted). Tubes can add that steel string “shimmer” and “silver” in an extremely elegant fashion. But please understand that this comes with a small trade-off: a slightly higher noise floor.
That’s actually why solid state technology overtook tube technology already decades ago. Plus in today’s digital world, players get more and more aware of every little amount of noise.
It is of course true, that in a recording situation noise is a concern. But in a live setting, in my opinion, a small amount of noise is usually not a factor.
Our Progression is built with plain and true tube technology. When designing it, we were EXACTLY after the above described elegant high-end response! We purposely went the old-fashioned way of hand wiring and adding no transistors at all in Progression’s tube stage .
Please keep in mind that ANY other studio-mic-tube-preamp on the market today is a hybrid circuit, where the tube is used for the lower frequencies only, but the high-end is processed by solid state components in order to satisfy today’s noise conscious customers. This technique, of course, does NOT provide the tube’s refined treble response!
In short, if you want to naturally enhance the high-end of your Pure pickup (similar to a condenser mic) and do not mind minimally increased noise, compared to a solid state preamp, the Progression is for you.
If you are not sure, you can always take advantage of our return policy and test the Progression at your home. I think this is an absolutely great unit, like the “icing on the cake” type of addition to the Pure pickups.
