This amp was purchased and put directly into storage until recently. It has barely been used and its condition reflects this. The Hiwatt SSP103 head is unique head in itself. Modeled off of a PA amplifier this Signature Series has 4 independent volume controls that work with each input on conjunction with a master volume. On top of that there is an active tone control circuit that gives you a variety of tones. For example if you cut the bass, the mids will be boosted in response. Very interactive  and sounds amazing. Very clear and clean that breaks up super nice through the 4 EL34's and 5 ECC83’s. The amp was made circa 2014 we believe, but we are awaiting confirmation from Hiwatt directly.
