The Fender Pro Junior IV (Lacquered Tweed) is the fourth generation of Fender's Pro Junior single-ended tube combo, a 15-watt EL84-powered amp, finished in a period-styled lacquered tweed covering rather than the standard black tolex. It carries the same simple, dynamic tube circuit the Pro Junior line is known for, dressed in a vintage-inspired aesthetic.
The Supro Thunderbolt is a compact tube amplifier delivering punchy, responsive tone with warm character. Its simple control set and portable size make it suitable for practice and small venues. The Thunderbolt appeals to players seeking vintage Supro tone in a lightweight package.
