What they're made of

• 14 Watts class A push-pull vacuum tube power using two 6BM8 pentode/triode tubes that are unique to Edward Amplification products. With these tubes, we can accomplish with five tubes what another amp would require at least seven to achieve. With less tubes, you get the same amount of versatility in a smaller package with fewer parts and less waste of power. The 6BM8 tube was chosen because when cranked up, these tubes have a pleasing sonic signature that complements the instrument you are using. These tubes are also very reliable and this is the reason why we can offer a 9 month warranty on them. 6BM8 tubes are still in production in Europe and replacements are available from Edward Amplification. Matched pairs are not necessary and no bias adjustments are required on The ED or The HED amp.

Vacuum tube information


• No feedback, non-standard circuitry is employed to create a distinctive voice as compared to many of the vacuum tube amplifiers of today. Removing feedback reduces linearity and creates more 'touch' or 'feel' from the amplifier. The preamp circuitry is arranged in a very simple way; even at the highest gain setting, the guitar signal passes through no more than two preamp tube sections and remains very quiet.



• Standby/Operate switch incorporated to help extend tube life and reduce power consumption during breaks.



• Celestion 12 inch "Greenback" 25 Watt speaker as standard on The ED combo amp. This speaker has been used on countless recordings and is the heart of just about every great guitar sound. Efficient and rugged, many amplifier companies have come to rely on this transducer for its response. It is, without a doubt, a big part of The ED's sound.



• Custom designed transformers for the power supply and output section made in Canada by Hammond Manufacturing. Hammond has a 70 year history in transformer design and building. Since these parts are not shelf items, they were tailor made for The ED and HED amplifiers.



• Two button, metal cased foot switch with indicator LEDs. Extends control of the amplifier for live situations. Foot switch included with every ED and HED amp.



• Hi-gain switching and separate gain Boost that is foot switchable. The Hi-gain stage boosts the signal enough to send the power amp section into saturation. The Boost switch provides another 8dB of boost, perfect for giving you that extra push on solos. This amp has been put together from a performance standpoint making it an excellent choice for players who know how to get the most from tube amps.



• Foot switchable reverb using a full size 17" tank that is directly tube driven and returned. The full size reverb has great depth and fullness compared to the otherwise narrow and thin reverb found on many smaller amps.



• A foot switchable tremolo circuit with unusually fast and slow oscillation rates that makes use of a triangular wave shape, not the usual sine wave shape. Unlike most other tremolo effects, there is little signal loss even at the highest intensity setting.



• Foot switch configuration as defined by the user to switch the Gain, Boost, Reverb and/or Tremolo functions. This is something never seen in an amp this size, or any other size for that matter. This actually gives the user a choice of what functions the foot switch will command. See more about this in Options.



• High quality ceramic tube sockets that will not deteriorate with age. All the tubes have mounting clips on them as well. Ceramic sockets are not prone to breakdown from heat and arching as the more commonly used phenolic sockets.



• Metal film resistors are used throughout the audio stages. Metal film resistors are quieter and more reliable than carbon composition type resistors.



• Plastic type capacitors are used where possible due to their heat and reliability characteristics. Reliability is extremely important for the gigging musician, we understand this and build it into our product.



• Tube buffered Line Out that is taken after the EQ section. This allows you the ability to use The ED or HED amp as a master with another amp or going directly into a mixing board or an effects pedal. Since it is buffered, plugging in will not affect the rest of the amp as is the case with many other line out designs.



• 1/4" Line In for an effects return or to patch into the output section, bypassing the preamp section. This can be useful for patching a multi effect processors directly to the output stage to give the processor real tube amp character.



• 8/4 ohm switch for connecting other speakers and cabinets. The 4 ohms setting can also be used on an 8 ohm speaker or vice-a-versa. Speaker Out and Parallel Out jacks allow you to connect more speaker cabinets for an even larger sound.



• 115/230VAC switch so you don't need voltage conversion if you take your amp overseas. This is a seemingly small feature that has great value to the touring musician who does not have an amp tech around.



• 200 Watt convenience AC outlet with plenty of room for a wall wart type supply or adapter. Another small but useful feature since many players use some kind of effects device.



• Overbuilt quality. The chassis, leather handle, speaker and feet are all fastened with #10 bolts - #8's would have done the job. The chassis is 16 gauge steel with a black epoxy powder finish that is meant to last. Both the ED and HED amp have a distinctive 'look' all in a small, well made package. Various colours and options available at no extra charge. Extensive warranty assures you of a wise purchase.
