Guitarists have known it for decades: there's just no substitute for an amazing tube amplifier. With their rich tones, loads of gain and sweet, resonating distortion, vacuum tubes produce sound that has kept them at the forefront of guitar amp engineering even as alternative technologies have cropped up all around them. The only catch is that tubes need to be replaced from time to time, but where some see a drawback, others see an opportunity - the chance to customize your sound with a set of the renowned preamp tubes produced by Groove Tubes. The gold standard in the preamp tube market is the well-respected 12AX7, and Groove Tubes brings not one, two or even three varieties to the table, but four. If you like the vintage, bluesy tone of a Chinese tube, take a gander at the GT-12AX7-C. Otherwise, check out the three models made in the hotbed of tube manufacturing, Russia. First up is the GT-12AX7-R, which delivers powerful tone with a little bit of bite, bright character and measured gain that makes it ideal for Fender amps. Next is the GT-12AX7-R2, with upscaled plates and a spiral filament to boost bass response and cut back on hum. You'll like this tube in a phase inverter position, especially if you prefer long plates. The third variation on the Russian tube is the GT-12AX7-R3, balancing things out with mid-sized plates and a solid midrange.
Of course, Groove Tubes has plenty more to offer than just the 12AX7. Another classic is the GT-ECC83-S, a European-style tube with well-behaved frequency response, great clarity and strong gain. There's a lot to be said for doing your homework when it comes to tubes, but maybe you'd prefer that Groove Tubes do it for you? If so, have a look through the selection of changing kits. These ready-made tube collections are transformations in a box for your amp, with options like high-gain Marshall and soft touch or high-gain Fender to get a ready-made combination for your favorite classic amp tone.
When you're looking to replace or upgrade your preamp tubes, you're in good hands with Groove Tubes. This is the label of choice for guitarists as high-profile as Slash, Bruno Mars and Scott Ian for a reason - they're simply incredible tubes that can turn your unassuming amp into a real powerhouse.
