Hiwatt SSD103 David Gilmour Signature 100 Watt Custom Head

Like the 100w Custom, this amp has normal and bright channels, but this has an extra input where the gain from each of these channels can be combined, each gain channel set as desired. The rest of the controls on the facia are the same, and the tubes at the pre-amp stage are all ECC83s. Now for the clever bit. Using a resistor matrix on the inputs for the mixing of the normal and bright channels, different component values are used than on a standard dr103, therefore there is no need for normal or low sensitivity inputs as the mixed output is the sum of the gain on both channels at the pre-amp stage.
