Well, it is not an all valve amp. In fact, it is a 100% Solid State amp, which explain the price.
However, don´t be too dissapointed by that. The amp sounds gorgeous and behave like a tube amp.
I´ve tried it and I assumed it was all valve until I was told it´s not. Unlike previous EBS amps, this one got a dual mid control which is ridiculous useful to shape the sound for a more rock oriented vintage sound. My opinion is it has more of a sound in itself than the other EBS amps and it´s a bit stripped down on features which makes it extremely easy to dial-in but still it has enough controls to shape the sound in just about any direction, so keep an eye of this one! And its on the EBS website now!
