Excellent tube! Considering 6L6 JJ's for the power amp tubes now! Review: tubes tubes tubes I wish i could give more information. - Hot rod deluxe 97 still had the factory fender marked tubes. It's clean sound and the overdrive was too Icepickky. I just didn't like the sound it was making anymore. Tried changing the knobs but it was not where I wanted to be sound wise. I bought this tube for the overdrive channel because some forum blogs said their over driven channel sounded much better to them with this tube in v2 . Also bought 2 other tube to try a selection of tubes some people gave positive comment on . I put JJ 12DW7 in v2 and put a 12AX7EH in V1 I wasn't that impressed. It was better. Still a little sharp on both channels little chimey. They didn't really help the clean channel that much. Tried a t-12AX7-S-JJ in V1 hmmm better..but the clean channel was blaa not a clean sound yet . overdrive sound bearable. Just for grins I put the dw7 in V1 and the 7EH in V2 and Wow my clean channel was super nice now!!!! overdrive ho hum . Put in the 12AX7 JJ tube in V2. Got a warmer sound and steady tone in the Overdrive. The clean sounded a little sweeter. Move tubes around a few more time in v1 v2 v3 . Best combination was JJ12DW7 in V1 JJ 12AX7 in V2 & V3 I left the stock tube in it as i felt the 12AX7EH electro harmex tube made a change in sound although negligible and maybe I was just imagining it but I put the stock tube back into A3 I will keep the 12ax7EH as a spare. It sounded a little chimey to me. Some people maybe able to make this sound into their own. I just wasn't in to it. I almost want to try another DW7 in v-2 . I am looking into finding what would be best in to the V3 socket. The loudness stayed the same. The volume setting sensitive stayed about the same or more touchy. But I'm happy now that the clean is sounding like an acoustic guitar instead of just too busy. Hard to explain maybe some overdrive in the clean. Maybe what they call microphonic. The overdrive is usable ,still undecided. maybe i think it need to sound by my effect processor and not the raw overdriven barky sound. But in a pinch I can make it work. I don,t like a lot of cords and electronic under my feet if I don't need it. The jj t-12ax7-s-jj is a great tube. Sounds better than the stock one and in some tube combination and amp it probably sounds fantastic ## Features - 12AX7 vacuum tube, - U.S. Product Code: 12AX7 - European product Code: ECC83 - For guitar and Hi-Fi amplifiers, - Can be used in any preamp or microphone application ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0002M728Y | | Amplifier Type | Tube | | Audio Output Mode | Stereo | | Best Sellers Rank | #3,457 in Musical Instruments ( See Top 100 in Musical Instruments ) #1 in Guitar Amplifier Tubes | | Brand | JJ Electronic | | Color | Original Version | | Compatible Devices | Guitar | | Connector Type | Solder | | Customer Reviews | 4.7 out of 5 stars 843 Reviews | | Enclosure Material | Metal | | Global Trade Identification Number | 00844632022081 | | Item Type Name | Amplifier Tube | | Manufacturer | JJ Electronics | | Material | Metal | | Mfr Part Number | T-12AX7-S-JJ | | Model Name | 12AX7 ECC83 | | Model Number | T-12AX7-S-JJ | | Number of Bands | 3 | | Output Channel Quantity | 1 | | Power Source | AC adapter | | Sound Profile | Balanced | | UPC | 844632022081 | | Unit Count | 1.0 Count | | Warranty Description | N/a. | ## Product Details - **Brand:** JJ Electronic - **Color:** Original Version - **Compatible Devices:** Guitar - **Material:** Metal - **Model Name:** 12AX7 ECC83 ## Images ![JJ Electronics T-12AX7-S-JJ Amplifier Tube - Image 1](https://m.media-amazon.com/images/I/61F+jDUTalL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect! *by L***T on January 28, 2026* Works exactly as it should!
