Review: These tubes dont get enough love!!! - I was a little bit apprehensive at first when trying these tubes because of the price, but it was totally worth it. I play a Vox AC4HW and it totally brought this amp to life. I was actually considering selling the amp before I put these tubes in. Previously I had a newer set of JJ 12AX7's in there, which I thought sounded good, and they were by no means bad, just not there. These ECC803S's just added a fidelity, clarity, more chime and robustness to my notes that scratched my itch. I'm no longer selling this amp. Both overdrive and cleans sound great, I play an Epiphone casino with Gibson p90's and a standard telecaster. Both sound phenomenal through this amp. All in all, I'm super happy, these tubes don't​ get enough love and praise. A lot of guys have reported using this tube in the V1 position, which I did try, but personally preferred both tubes in my V1 and V2 positions. Enjoy these tubes, they are worth the price. Review: It’s a modern production tube ..🤷 - It’s a modern ecc83/12ax7. This one is fine, but of course it’s always hit or miss with modern production tubes. ## Features - The jj ECC803 is a long-plate version of the standard 12AX7, - The longer plates give the tube higher gain - It has a rich and full tone with creamy distortion that does well in any 12AX7 application.

This one is fine, but of course it’s always hit or miss with modern production tubes. ### ⭐⭐⭐⭐⭐ super fat, and super loud *by C***N on November 26, 2014* I've been a fan of JJ preamp tubes for a while now; it was them that fully weaned me off the idea that NOS is always better. In particular, JJ's spiral filaments lead to an occasionally miraculous reduction in noise. That feature is somewhat obviated by the brutally high gain on this tube, but if you've got a properly shielded guitar with properly wired humbuckers and you're not standing 2 inches away from your speakers, it still sounds pretty surprisingly quiet. Even the best vintage tubes I have still get parasitic oscillation at extreme levels, and this one is completely clear even when it's pushed far past levels I'd actually use. The gain is extreme. My clean channel has gone from sparkling to crunchy, and my OD channel has grown a new set of teeth. I can still dial the guitar volume back to get clean, warm, and rich. Compared to the ordinary JJ ECC83 the sound is much more thick and saturated, but it is noisier. For my style of music, that's acceptable. I haven't yet tried to put it into my V2 slot so it only affects the drive and not the clean, but it has my clean sound like what I want it to sound like. I don't think I'm going back to regular 12AX7s. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.om/products/3687307-jj-electronics-t-ecc803-s-jj-amplifier-tube](https://www.desertcart.com.om/products/3687307-jj-electronics-t-ecc803-s-jj-amplifier-tube) --- *Product available on Desertcart Oman* *Store origin: OM* *Last updated: 2026-06-22*
