Hand-wired, classic tube sound from across the pond - or is it the dark side of the moon?

Based on the Custom 100 head, but with special modifications as commissioned by Dave Gilmour of Pink Floyd himself, the DG-103 adds a bit of modern sophistication to the classic performance amplifier. In addition to the Bass, Treble, Presence and Master Volume controls, the DG-103 uses a specially linked input system, where the gain of each channel can be altered to suit different musical styles. Built using Partridge transformers, 4 - ECC-83 tubes in the preamp section, 4 - EL-34 tubes in the power stage, and is rated at 100 watts output, with switchable 4-, 8-, and 16-ohm impedance.

A look inside the amplifier will reveal point-to-point hand wiring, turret tag boards (no printed circuits), and hand laced wiring harnesses. The power and output transformers are manufactured by Partridge, the original 1970s supplier to the original design sheets. The components and wires are the modern equivalents of the vintage components, 1-watt carbon resistors, and wound polyester capacitors being used throughout.

  • Power: 4 x EL-34 tubes
  • Preamp: 4 x ECC-83 tubes
  • 100 watts
  • Dual channel: normal and bright
  • Adjustable 4, 8 & 16 ohm output impedance
  • Linked input system
  • Individual channel volume
  • 3-band EQ
  • Hand-laced wiring harnesses

The cleanest sounding amp I've ever heard! Terrific tone. No hiss, humm or distortian. Sounds just like my favorite guitarists, DG (as it should).

This classic gem is soooooo great. From the rich ,ringing superior bell like tones to the absolute dependability,no other can top HIWATT !!, I have used the old and these new ones in studio and on world tours, and every guitar and amp technician says the same thing....HIWATT is spend the dough on any of these and you will be thanking yourself later on....period !
