Classic bass/guitar sounds, blackface-style equalization, amp head with professional specs due to its active DI together with a Lundahl PRO output transformer. All hand-made with high quality components. Output stage based on a pair of 6550 tubes working in push-pull with PRESENCE and MASTER controls. Tube-controlled DI with Lundahl Pro output transformer. Excellent signal-to-noise ratio.

*In the Pre-EQ position (that is, before the preamp section) the DI output signal stays unaffected by any of the amp’s own controls –a flat tone that best suits your sound board in live situations.

**In the Post-EQ position the DI signal draws from the second stage’s preamp output. So now the amplifier controls (Gain, Bass, Middle, and Treble) are also part of the DI. This is perfect for professional recording studio situations when you want to get the actual tone of a tube amplifier without putting a mic in front of the speaker.
