If you read this blog with regularity, you know that I love NOS tubes. Who knows? Maybe I’m being a cork-sniffer, but the significant impact NOS tubes have had on my amps has led me to preferring them over new production tubes. Unfortunately, NOS tubes are getting scarcer and scarcer, so I suppose that eventually I’ll have to get new production tubes.
Now a company that I’ve tended to steer away from is Groove Tubes, mainly because they’re just re-labeler of various OEM tubes. They just measure voltage, match ‘em up, relabel them and sell them as their brand. Nothing wrong with that, but I haven’t met a Groove Tubes tube that I’ve liked, until I discovered the Groove Tubes GT-6L6GE Re-issues.
Before I go on, I should clarify that I’m not talking about the current production 6L6GE’s, which are assembled overseas. The tubes I’m talking about were made in the USA up until about 2003, as far as I can tell.
What makes these tubes special is that they’re constructed of NOS materials (except the glass), and to the same specs as the original GE 6L6′s of old. Plus they were constructed in Southern California, so the quality is incredible. These tubes rock! To be honest, I’m not sure of all the details of their production, but I got the information from Brent Jesse @ audiotubes.com who recommended them to me.
I bought two sets so I could have a spare set, and have been in tonal heaven with my Hot Rod Deluxe! The cleans are lush and deep, and the overdrive is creamy smooth. I have other GE power tubes, and I’ve gotten used to their smooth distortion. These GT-6L6GE’s are no exception! In addition to their smooth breakup, they also don’t compress much, which is another thing I just dig. I prefer a more open distortion.
I compared these to both JJ’s and regular Groove Tube 6L6GT’s, and these just blow them away. The JJ’s and GT’s have nice, clear cleans, but forget about their tone when cranked up. The tone is harsh and gritty, even if I bias them a little hotter than spec; whereas the 6L6GE’s remind me of the breakup I get from my Plexi clone – without hot biasing! Amazing!
As these are no longer in production (don’t confuse these with the new 6L6GE’s), they’re a bit more expensive than the new production 6L6GE’s; $80 per pair as opposed to $55-$58 a pair. And because they have the same labeling as the new ones, it’s hard to tell them apart. So I recommend that if you want to get a pair, get them from a source you trust. As I mentioned, I get them from Brent Jesse Recording and Audio, and having purchased several tubes from him, I trust him implicitly.
All that said, I will be getting a set of the new production tubes to make a comparison, as they are also made with NOS materials, though assembled overseas. Who knows? They may just sound killer as well!
