Powered by a 12AU7 vacuum tube, this gives an amazing warm sound ranging from clean (ish) and jangly, right up to dimed Marshall stack territory. This can be used as an amp "head" with any guitar cabinet ranging from 4 ohms up to 16 ohms. It comes with a 4 speaker cabinet built into a vintage Acid cigar box. That's what you hear in the demo.

2025年1月9日 · The 12AU7 (European: ECC82) (P/N 154-041, 154-0041-00, 154-0287-00) is a dual medium-μ triode vacuum tube with a center-tapped filament for use in either 6.3 V / 300 mA or 12.6 V / 150 mA heater circuits. It is likely the first tube manufactured with a B9A (Noval) miniature 9-pin base (from 1946).

The 12AU7 and its variants are miniature nine-pin (B9A base) medium-gain dual- triode vacuum tubes. It belongs to a large family of dual-triode vacuum tubes which share the same pinout (RETMA 9A). 12AU7 is also known in Europe under its Mullard–Philips tube designation ECC82. [1]
