Often imitated, but never truly replicated, there's nothing quite like the rich, warm sound produced by tube amps. Similar to how swapping the strings on your six-string will impact its tone, switching out the tubes in your amp gives you the chance to experiment with and really customize your sound. There are dozens of tubes for instrument amps from all your favorite brands available in this section, so whether you're here to further refine your sound or you simply want to stock up on a few more of the tubes you already know and love, you're definitely in the right spot.

The tubes for instrument amps you'll find on these product pages fall into three main categories: preamp tubes, power tubes and rectifier tubes. Preamp tubes are the first ones in the signal path and are generally considered to be the more crucial tubes in your amp because they handle all the raw sound shaped by your instrument and pedals. If you want to discover all the different sound capabilities of your amp, a great place to start is with its preamp tubes.

Next up are power tubes. Just like their name suggests, power tubes pump out all the wattage needed for a wicked and wild performance. They take the tone created in the preamp tube(s) and drive it to your cabinet's speakers. Power tubes can have a huge impact on your sound, which is why it's important to choose yours wisely.

Last, but certainly not least, there's rectifier tubes. Although the rectifier tube doesn't handle the audio signal directly, it still plays a huge part in sound production - its primary function is to convert the AC voltage coming in from the wall and turn it into the DC current the amp's preamp and power tubes need to blast your signature sound.

Not sure where to being your search? Filtering by category and brand are both fantastic ways to browse this catalog. Checking out the best sellers and top-rated tubes for instrument amps is another great way to see what's available. When it comes to selecting the tubes for your amp, there are no right and wrong choices, there are only the tubes for instrument amps that work best for you.
