Package of 5. The JJ Electronic 12AX7 / ECC83 has quickly become a modern classic in preamp tubes. Its rugged design and rich harmonics make this tube an obvious choice for musicians who need a reliable and high quality tube at a reasonable price. The balanced tone of the JJ 12AX7 works well in any amp. This versatile tube sounds excellent in clean amps offering an amazing dynamic response while also proving itself in high gain amps with its low noise and noticeably less microphonic issues than other tubes. The warm highs and transparent lows make it a great choice for any position in a tube amp. The JJ 12AX7 is the go-to tube of many amp builders and touring musicians.

I have a Marshall DSL40C tube combo I bought used and it needed a power tube. I figured I would just replace ALL the tubes since I didn't know the amps history and I would then have a baseline. Instant to e improvement! They biased easily and Ive had them in there, regularly using the amp every weekend for hours with no issues. I'll definitely "buy again" when these need replacement.

These JJs do the job so I’m happy with them, however I purchased 8 of them and found 2 were bad already, my amplifiers would sound good for a minute then after warmup the sound turned brassy and saturated. Since you can’t return tubes it’s a gamble.

Great sound from the JJ tubes. For the money they are hard to beat.

Great price for products. The Peavey 6505 I was retubing has 6 preamp tubes, so a 5-pack was only bought because of the price.
