‘The Rave’

If you’re looking at this then you have undoubtedly heard of the legendary amp engineer ‘Howard Alexander Dumble’ and his unique amazing treasured designs owned by great guitar players like John Mayer, Robben Ford, John Bonamassa, Stevie Ray Vaughan, Eric Clapton and Eric Johnson.

This amp is no exception in that it is custom hand made using high quality components and based on Dumble’s Circuit design ODS 3rd Generation Schematic which incorporates all the best features.

Indeed this is a ‘Rare’ Unique Dumble 50W RMS Combo Guitar Amplifier Clone.

Included is a 3 year, return to base, warranty on parts and labour exclusive of Valves and Speaker.

This is a quality professional build. I am a qualified, experienced Engineer.

Purchase with confidence!

My amps are built problem free! to last 20plus years!!

Compare that, with current major brand production line amplifiers, which give 12Mths warranty and classically fail soon out of warranty period! Good luck Trying to get them to be responsible!!

Comes with a Custom ‘Orange’ Brand 16 Ohm 60W speaker. 

It has Hammond 1650PA 60W output transformer, which gives plenty of headroom, with 4, 8 & 16 Ohm load tappings. This gives various options for the external parallel speaker output jack so load tapping can be selected based on overall speaker impedance if internal 16ohm speaker connected i.e. two 16ohm speakers in parallel use 8ohm tapping for full output power.

The power Transformer is a Hammond 290D2EX with a 10H choke for the High Volt power supply.

High Voltage Capacitors are F

&T brand made in Germany & IC made in USA.

Tone Capacitors are Orange Drop and Resistors Carbon Film for tonal clarity & stability.

The build is hand built on a custom, gold plated contacts PCB, using 3% silver solder and silicon coated HV wire for chassis to board wiring. Shielded cable is used from control pots and input output jacks to PCB.

The output is a Push Pull Class AB configuration with two EL34 II matched JJ Tesla tubes.

The output tubes have external access fine bias adjust for matching with external monitor meter sockets.

Pre-amp tubes are ECC83 (12AX7) Tung Sol and JJ Tesla.

It has an  ‘Active Tube’ Effects loop with variable send and return controls and Active Spring Reverb driver circuit with Depth and Dwell controls, on rear panel, into a 3 Spring Medium Delay Acutronics Reverb Tank.

These are custom EXTRA’s as normal Dumble amps don’t include ‘Active’ Effects Loop and only 12 where ever made with Reverb circuits!!

It has Footswitchable pre-amp boost and fully adjustable foot switchable overdrive channel. Footswitch and XLR cable included.

Input is selectable between FET buffered Pre-amp input jack or Normal direct Valve pre-amp input jack.

This amp sounds amazing with rich harmonic tonal clarity, breaks up controllably, for even harmonic overdrive & sustain, and is a loud! 50Watts RMS! To cut through the mix or live band performaces.

Amp cabinet has ball bearing casters which will be removed packaged and stored inside cabinet as with the output tubes and Footswitch if couriered. 

Cabinet also has rubber buffer feet if preferred.

Due to size and weight pick-up is preferred but can arrange courier at buyers expense. 

P.S. Insurance is not included in courier price but can be provided as optional extra.
