  • Crate - Reborn and Beautiful

    As reviewed by gordon pierce on 5/3/2014

    I have these tubes in my Peavey and really like them. On a whim, I decided to retube my 13 year old Crate Blue Voodoo BV120H (The same Blue Voodoo that has been flamed for more than a decade as unreliable and lacking character but has never broken and is still in use). So, with a new quad of JJ 12ax7's in the preamp and a quartet of these Ruby's for the power, the Crate has new life. The JJ"s went in first, which took the ice pick highs out of this bright amp. Then the Ruby's went in. After a warm up and rebias, I found that the Ruby's accentuated the mids. Nice, warm, clear, articulate cleans. I'm not going to even try to compare them to the Groove Tube rebranded Sovteks that came out because they were old and tired, but the tones in this Crate are better than I remember. These Chinese relabeled tubes gave my tired old Crate a lot of punch, sweet clarity and character. If your amp is lacking that certain something that you originally fell in love with and your thinking of new tubes, I'd give these Ruby's a shot.

  • Great bang for the buck!!!

    As reviewed by JChain on 11/25/2009

    For the price, these babies are awesome. I've only had them for a week, so who knows how long they will last. But I slapped them in my old peavey and they sound great. If they last long, I'd buy another set next time I need 'em.

  • Great Sounding Tubes

    As reviewed by Starriddin on 3/16/2009

    I put these tubes in my B52 AT-100 head and was absolutely blown away. Warm, smooth, articulate, sweet breakup, are a few words that come to mind. Don't be scared that these are Chinese tubes. They are sweeeet and priced right if you get them 2 or 4 at a time. Make sure you re-bias your amp to the new tubes' rating. Bottom Line is these tubes sound great!!!
