01/29/14  A 2014 NAMM Review! NAMM 2014  


1/06/14   A BIG sneak peek at JJ Electronics' new 300B powered guitar amp! Check it out here!


11/19/13    A first look at another new tube from JJ! Over the last few months we have been testing yet another new tube from the good people at JJ Electronic. The JJ ECC83 MG is a “Mid Gain” 12AX7 type tube. It utilizes a medium length ribbed plate design that is much like the old Amperex and Brimar European designs. It retains all of the definition and detail that the ECC83S short plate and the ECC803S long plate tubes have but it has slightly less gain than the ECC83S but a bit more gain than the ECC803S.

Sonically it’s nice and thick sounding with a good edge that’s not brittle. It has plenty of definition even when used in an amp with lots of gain and the microphonics are very low. The ECC83 MG is a little more polite than the ECC83S which is pretty aggressive. The ECC83 MG has a fair amount of harmonic density but remains very open sounding whether played clean or overdriven. All in all it’s a really nice sounding tube and we will have the first production run in late December!

Hello all Eurotube members of the Tube Hall of Fame.

I purchased a Blues Jammer amp from a fellow who purchased it from one of my customers. When the amp came in I put the amp on the Oscope and I've never seen such a terrible wave form. The amp had been violated with a weird assortment of tubes namely 2-GE 12AX7's, Jan Phillips 12AT7WC, Sovtek 12AX7LPS, 2- Tung-Sol 5881, JJ 5AR4.

I First replaced all the preamp tubes. Much better but still had a weird wave form. Replaced the 5881's with JJ 6L6GC's – Yea, perfect. Improved performance and output swing. The only tube kept was the JJ 5AR4.

JJ all the way, baby!

Older NAMM reviews are part of the old What's new page below.

You can find the old "What's New" page which was a historical timeline here.

Facebook removed the “Discussions” feature where we had put up a lot of reviews and information, so we decided to use our “What’s New” page for write ups about what we do here at ET. Each link will take you to a review page with photos and the newest reviews are on top descending to the oldest.
