Sometimes having the classic tubes really adds that professional warmth and brilliance to your song...unfortunately many of us don't have the money to actually afford a hardware tube EQ.
Good news! We have the ever so affordable virtual emulation of a tube EQ by G-Sonique. It's their Pultronic Tube EQ.
Now, when I first popped this baby open, I was a bit confused at what all exactly I was doing...mostly when it came to the ability to change what type of tube you are using. So, certainly the use of this plugin for anyone new to VST plugins you may find it a bit confusing, but most any one who has been doing music for quite awhile and knows their way around a regular EQ, you'll probably understand what you're doing right quick.
The Pultronic Tube EQ features 17 presets, I usually found at least one preset would also get me close to what I want, then it just took a little noodling around with the knobs till I got exactly what I wanted. If those presets don't do it (even after noodling with the knobs) you can also change what type of tube that is used for low frequencies and what tube you use for higher frequencies, and each can be changed independently, so there are bunches of combinations (I wouldn't necessarily say endless combinations though)
On the low frequencies you have the choice of: Class A Tube Warm Tube Vintage Tube Dirty Vintage Tube (my favorite, next to Warm Tube) and a 12AX7 Tube
On The Highs we have: all the same tubes plus Piano Tube Piano Tube II and Classic Tube
Using tubes in combinations can help add a mind blowing quality to your music.
Lastly, there are 3 knobs that I feel in love with: The Warmth knob, Saturation Drive knob, and Brilliance knob.
Each one does exactly what it sounds like: Use them to either boost or lower the warmth, or saturation, or brilliance.
Now, I personally didn't have to spend a dime on this plugin AND before you gasp and scream “Pirate!” let me explain real brief: This plugin came free with my DAW. Now that may raise the question about your idea of if it would be worth the dollars or not. And to tell you the truth, I would have spent the 45+ dollars on it (38 Euros) (I don't feel liek doing the conversion for the exact dollar amount). For the power it has, I think that is a fair price, especially for the amount of quality it adds.
Oh and the last thing I think I should mention: it's very stable, but every time I run it, it seems to take a few seconds longer than any other VST to load. To me it is no big deal. But, yeah it is a little bit intensive on the CPU, but not as much as some other plugins I have seen and used.
