Here's the test results from testing my ART TUBE MP STUDIO with my VJ head

WOW. It really does BOOST the VJ's volume and gain. By boosting the INPUT and OUTPUT levels it adds much more of both - you can overdrive the tube easily. It also has a +20db gain button (right below the green led) that slams it like a tubescreamer. The extra "noise" isn't that bad really with the VJ (noticed it more with my computer when using it as a DI in Logic)... It adds a true TUBE warmth that isn't bad at all - I'm probably going to order another one and keep this lil' baby hooked to the VJ.

It not only boosts the overall volume for clean & wide open "dirty" but it will make it louder and Dirtier too even dimed. I love it and for $30 it's a great addition to the family. I'm gonna take it apart tonight and try an EH 12AX7A I have in my drawer. Another bud of mine in another guitar forum says changing the tube really helps it "shine". I recommend this baby to anyone as a cheap "boost" and a great gain boost too at lower volumes. It works like a Tubescreamer! BUT A REAL TUBE Tubescreamer. I'm loving the differences I'm getting from it. It's a great "mod" and doesn't require soldering anything or drilling, etc. You'll love it
Now running an Eleven Rack with Pro Tools 10.3.3 - it's amazing and I'm having ball with it - worth every penny. PT 10 is tops IMO and the Eleven Rack is a work of art!

I think if you hook up your guitar to it thru the Input and Output jacks, and then either turn up the input/output levels or use the 20dB boost button, it should boost the signal and push the amp. right?

have you tried recording with it? If it's not a problem, can you record two riffs (one with and one without the preamp?)

it's a BOOST and also gives it a warmer "buttery" sound when playing it at lower volumes - it boosts the cleans and really LIGHTS UP the gain too - I LOVE IT! Will try to post clips but I gotta leave right now - I was using it as a simple DI on my computer - it gives any sim a tuber sound and works great but when it's used with a Valve Junior (or BH I'm sure) it really adds a PIZAZZ that requires no soldering, drilling, etc. GET ONE AND TRY IT FOR YOURSELF - you'll be pleased as punch! Works great with computer playing too. If you don't think it's a great $30 MOD I'LL EAT YER HAT!

I just got the VJcombo for my g/f and spent the day yesterday trying different things with it. Bottom line is the valve Jr loves pedals. I was sold 5 minutes after I hooked my POD up to it. Soon as my tax check gets here i'm ordering the head/cab for me.
