Thanks to the success of the Blackstar Series One 100 and 200 heads, Blackstar have refined their design in the S1-104EL34 model. As the name suggests this one is loaded with 4 EL34 tubes. It sits between the S1-100 and S1-200 in terms of price so if you want an S1-100 geared towards a more "British" power amp overdrive - the S1-104EL34 could be for you.
