This GA-5 Skylark is a great little amp, totally versatile, the tremolo sounds beautiful,  turning up the volume it gets a wonderful crunchy vintage tone, the new Weber speaker makes it strong and solid sounding, this amp is small but indeed a very effective weapon for any guitar player, at home as on small stages a well.

About the Tremolo -footswitch:

The 1961-era GA-5T Skylark has tremolo built into its circuitry – it was meant to be controlled from the amp’s own panel (speed/“tremolo” knob), it did not include a factory footswitch, that’s a later modification, an aftermarket addition.

Musical Character of the 1961 Gibson Skylark T:

The 1961 Skylark T is known for its intimate, expressive voice—a small tube amp that responds like an instrument of its own. With only a few watts of Class-A power, it breaks up early, giving guitarists a warm, Velcro-soft overdrive that blooms as you dig in. Clean tones sit in the mid-rich, vintage American zone: rounded highs, a gentle low-end roll-off, and a vocal, almost woody midrange that pairs beautifully with single-coils and P-90s.

The tremolo circuit adds a pulsing, organic shimmer, the kind of bias-wiggle throb that sways rather than chops, perfect for slow ballads, blues vamps, or atmospheric chord work. At edge-of-breakup settings, the amp reacts dynamically—touch-sensitive, shifting from mellow cleans to gritty bark with small changes in picking attack.

Cranked, the Skylark T delivers a raw, harmonically rich grind, more vintage garage-rock than high-gain, with a compressed, singing sustain shaped by its tube rectifier. It’s a studio favorite because it sits in the mix naturally and records beautifully at manageable volumes, offering the unmistakable character of early-’60s American tube tone: simple, soulful, and musically honest.
