If you’re running an all tube bass amp, a hybrid amp (tube preamp/solid state power amp), or a tube D.I. you owe it to yourself, (and your bass ;) to try out some different preamp tubes. Preamp tubes can have a large positive impact on your tone. I only sell preamp tubes that I feel compliment bass guitar by adding detail and texture to the notes, with nice vacuum tube overtones and harmonics, and a 3 dimensional sound stage.

Choice preamps tubes are the easiest, quickest and most economical way to transform the front end of your amp, giving you that rich tube tone. My favorites are Tung-Sol 12AX7, Electro-Harmonics 12AX7, Mullard 12AX7, and JJECC83/12AX7, in that order. All 4 are great and will sound different depending on your amp/cab and bass combination, and your playing style. We can help find whats right for your specific combination, but generally speaking any one of these tubes will most likely be better than what you currently have, or a nice alternative to your current favorite, if you already have experience rolling tubes.

Premium high gain Twin Triode featuring ultra-low microphonics, and a big, warm and very musical soundstage. Performance surpassing NOS original in all areas.

• Improved reissue of the Vintage NOS Tung-Sol 12AX7
• Superb linearity with a dynamic 3-D sound
• Preferred by guitar technicians for re-tubing and upgrading, but equally well suited for HiFi applications
• 7025/ECC83 equivalent
