Bare Basics Design Suits Any Gig

Unlike most amps from ENGL, the Thunder series were designed with everything stripped back to the basics, ensuring any player can deliver a high-quality performance at any gig. Its 3-channel setup provides a versatile range of tones, with controls for the 3-band EQ, volumes, and gain offering everything you need to dial in the perfect sound for any playing style. At only 50 watts, the Thunder 50 E325 can still pack a heavy punch, with its EC83 and 5881 tubes offering beautiful tones many players will love.

Excellent Connectivity

The amp features a range of ins/outs for players to expand their performance, allowing the connection of a footswitch to control the amp’s channel select and provide quick changes during playing. The amp’s FX loop allows the connection of external stompboxes to expand its tonal possibilities, with a balancer to adjust how much the amp is affected by the effect. Four poweramp outputs provide players with the choice of connecting the amp to 8 Ohm and 16 Ohm speaker cabinets.
