For almost a century, musicians have been using amplifiers with their instruments. Tubes have been there since the beginning, and their unmatched sound quality and characteristics have kept tube-based amps at the top of the music scene right up to today. There are three different types of tubes that can be found in an amp, and of those, preamp tubes are easily the most crucial to your final sound. When you want to customize your tube amplifier's voice, the preamp is the place to start. Preamp tubes are also the most common, since they do the heavy lifting of tone generation. While rectifier and power tubes are often left out of hybrid models, any amp that's not entirely solid-state ought to have a preamp tube. The reason for this is that preamp tubes are effectively the voice of the amp, working as translators that convert an electric guitar signal into an audio tone. The impact of changing them could be compared to new guitar strings or drum skins, and just as in those cases, the choice is a personal one.

If you play rock or metal, you might prefer a smoother, bolder tube with distortion-friendly character, whereas a punk or alternative musician will probably choose a tighter and cleaner-sounding tube. Depending on your amp's design and power level, it can have one preamp tube or several. When there is more than one, it's worth taking a look at the amplifier's wiring diagram to see which one comes first in line after the input: that one will have the biggest impact when changed. The secondary preamp tube positions that come after it will then give you the opportunity to combine different tubes to further fine-tune the amp's tone. Whether you're changing tubes for customization or just doing a routine replacement with another of your favorite preamp tubes, you'll find plenty of options here to choose from. You may even like to swap in different tubes for individual songs and venues. With no two tubes sounding exactly alike, a little bit of experimentation should help you discover which ones create the perfect tone and gain for your own style.
