All Bulldog amps are completly handwired. The components are mounted on 1,5mm fiberglass eyelet boards. Our wiring method promotes optimum circuit stability and features very short signal paths.Only high quality components, most of which are of USA manufacture, are used in our products. For example, Switchcraft jacks, Carling switches, and ceramic tube sockets. All the other chasses are made of steel for maximum stability. The transformers are US made as well, and they are designed and sized for the best tone possible. The material of the screws and self- fixing nuts we use is VA. So you get an amp that makes no trouble for a long time. Bulldog products are made for eternity! Every amp must be controlled and is runnigng for several hours after finishing. A short signal path and shielded wires are resulting in that dynamic tone you were looking for so long.
