This was the first boutique lunchbox amp to make it to the main stream. Built like a tank and sounds great. Very loud at 30 watts, can keep up with drums no problem. This is a big iron amp that sounds in the ball park of a Marshall plexi. Great shape, never had an issue. Ready for a test drive.

√ Class A 30 watt amp.
√ Takes one or two power tubes, using one tube makes it a 15 watt amp, easier to push the power tube.
√ Takes all types of tubes: 6L6, EL34, KT66, KT77, KT88, 6V6 and EL84 (with adapter).
√ Can swap power tubes without needing to bias amp.
√ Has built-in attenuator.
√ Line out is part of the attenuator, power tube is included in tone.
√ Low voltage switch for different tone; and at a lower volume.
