Premium 12AX7/ECC83 Gold Pin Preamp Tube - High-Quality Audio Vacuum Tube for Guitar Amps & Hi-Fi Systems - Perfect for Musicians & Audiophiles

Replaced the stock psvane tubes in my ART solo MPA and ART solo VLA (preamp and compressor) and all i can say is wow! I have not burned the tubes in yet, just tested for functionality so far, but instantly it made the sound, only what i could describe as, “cleaner” and more distinct, with a whole lot more warmth. Silky smooth comes to mind. Let me say though the Psvane stock tubes did not sound bad at all, they have a distinct punchiness to them that i could see being maybe better suited for guitar and drums, however for vocals which is mainly what i will be recording i would recommend the gold lions hands down for that smooth and creamy vintage warmth. Also reccomend the seller tonal tubes. They understood the nature of the product packaged it carefully and had it delivered two days ahead of the estimated time. Excellent seller excellent product!
